Has anyone else had a terrible experience thus far?

I bought my chromecast the day it came out. Since I have gotten it I have had nothing but problems with it.
First, getting it to connect to my WiFi was a complete pain in the ass. It took me 2+ hours and my final solution was to disable NAT, connect the chromecast, then re-enable NAT. So, fine. I got it to connect and it kind of worked.
~20% of the time it works flawlessly.
Now, the other 80% of the time it will say ready to connect and say it is connected to my home WiFi but the chromecast app either says there are no devices or there is a device that needs to be setup. Also, if I manage to get it to work and start playing a movie on netflix, I often lose the control over it during the course of the movie and the only way to stop it from playing is to unplug the dongle.
Has anyone else had this awful of an experience? What would be the cause? I am contemplating going and buying a new router (mine is a modem/wireless router for centurylink MN: C1000a).

Calls to mind the Anchorman quote: "60% of the time, it works every time."
My first thought is that your AP restricts client-to-client communication, resulting in difficulty communicating between your phone and the Chromecast. However, that doesn't explain the NAT issue you had.

I had some of the same issues with losing controls and not being able to pause or stop a movie/video but the Remote Cast app from the market helped with the loosing controls part. As far as the chromecast losing the network connection unfortunately I ended up hooking up a cheap belkin router in addition to my good router and it works with the belkin just fine without loosing connection.

Having similar issues. Using Samsung LED TV. Setup seemed ok, but 'casting' anything from my phone is slow and tediously painful, it even seems to make the apps on the phone slower to respond than if they are *not* casting, i.e. Netflix loads quickly and transitions normally, but when I attempt to "cast" the phone app seems to act slow and the TV seems to take almost a full minute to catch up to what I selected from the phone, if at all.
I have a brand new router; My samsung TV is wifi enabled, I just don't use it much. The thought occurs to me that perhaps there is wifi RF interference so I may attempt to disable the samsung's wifi feature tomorrow and see if the Chromecast behaves more responsively.

I had troubles connecting to my Verizon FIOS Actiontec router. But I learned years ago not to fool with that router as it makes other things worse. So, I've had a separate Wifi hotspot for years (just another router with the router stuff turned off) and my Chromecasts (I have 4 of them) work just fine with that. If I were you I'd go to Fry's, or equivalent, and buy a cheap router and set it next to your existing one. Routers go for as cheap as $14.99. The one I use cost about $25. Your life will be much easier.

My experience has been flawless using the Chromecast in two different locations. Both locations have routers and wireless AP's that run either DD-WRT or Tomato however. There doesn't appear to be anything inherently wrong with the Chromecast hardware overall (but you might have a dud unit), but the reliability of it obviously depends on your wireless AP and router equipment.
What equipment are you using for your wireless AP and router?

Haven't had any issues with mine or my friend's. Two different routers, but both setup and run perfectly. Might be a router specific issue.

Mine has been flawless. It set up in seconds and works perfectly.
I have been casting a bunch of YouTube and netflix with no issue.

I've got about the same experience. Turns out as soon as I start casting my Wifi network performance is reduced to rubble and the Netflix & Youtube apps on my phone freeze up. Without casting pings to the (Asus RT-N66U) router is around 5ms. After casting the pings are all over the place (200ms - 1sec) with lots of dropped packets.
I have 3 out of 4 signal bars on the Chromecast, but the problem appears to be reduced if I bring it closer to the router. Almost seems like a HW problem.
I'm using Shibby's Tomato rev 124 on the router btw.

Google has it on their router page but sounds like you're not running the stock firmware, so could be any number of things.
First thing I'd check is UPnP and multicast. If either are blocked/disabled it will cause trouble.

I run a slightly older netgear router with tomato firmware and everything plays fine... I keep UPnP off because (at least on my router's model) I was told it can cause problems.

Try turning UPnP off on your router page, as well as turning off Wireless Isolation

Yeah UPnP really depends. If it works, leave it. If it doesn't, it's worth toggling to see if it makes a difference.

Mine works flawlessly as long as the wireless signal is good. Setup was an snap (have an ATT Uverse/2-Wire router). All I had to do was put in the password and it connected on 1st try.
Used it the other night in the kitchen and I kept losing controls and it kept dropping out before I remembered that the kitchen TV is in a bad spot for wireless. Moved it to another TV and it was rock solid again.

Just bought mine today, setup and use work great. The only thing is no fullscreen casting (the experimental one) and some frame dropping not using it as it was intended (casting a remote desktop tab for fullscreen games).
It may solve some router issues to include an extender or additional bridged router that has it's own SSID. Just in case it's a compatibility issue. It might help to have a clean slate to troubleshoot with.

I had a number of issues originally when first using it, the setup was very hit or miss (kept failing) and I had huge reception issues.
Later Google OTA updates appear to have resolved the setup issues I had on earlier builds and I ended up solving my reception issues by purchasing an HDMI extension cable and migrating my chromecast out of my home theatre cabinet where it was getting impaired wifi signal.

Yes, contrary to what Google might imply, Chromecast does not have to be on the same wireless network as your other wireless devices. As long as they're bridged, it works fine. That's how Chromecast can be on 2.4 GHz WiFi while my phone is on 5 GHz WiFi, and my computer is wired.
The only hard requirement is that for setup, you need a supported device with 2.4 GHz 802.11b, 802.11g, or 802.11n wireless because it needs to connect to the Chromecast's internal access point that is available during setup.

I have the same router just running merlin instead of tomato. No issues with latency.
I did try it at a friends house and they had some netgear router and latency went through the roof for everyone. Unsure exactly what happened but made the entire wifi network lag horribly.

Chromecast network issues

Does anyone elses Chromecast wreak havoc on their network? My other devices slow down, and my router seems to occasionally go in and out. What might solve this? It's not a speed issue, as this doesn't happen when streaming on the computer or wii.

standing by this thread. My tablet phone and laptop all have expirienced this slow down. speed test is still showing a 25ms ping and 30mbps down, but youtube and play store are timing out on both my phone and tablet, and when trying to cast from any device, the entire thing lags out. then i lose the cast button...
haven't found a solution yet

When I set up the Chromecast for the first time, my router totally locked up. I rebooted it and haven't had any problems since. I am running an ASUS RT-AC66U w/ Merlin-ASUSWRT firmware.

I have a similar problem. I use my Chromecast and then my router chokes up till I reboot it.

My dlink router was from 2007 and chromecast would lock it up completely. Bit the bullet and bought a new router and haven't had any issues since.

Chromecast slowing my internet connection
Experiencing an issue kind of similar to the OP's. Basically while my Chromecast is plugged into the TV, even when not in use, it slows my internet connection. I normally get between 25mbps and 35 mbps down on a speed test and gaming as well as file downloads work great. As soon as I plug Chromecast in, my download speeds on a speed test drop to about 1.5mbps to 6mbps. All of a sudden online gaming is basically impossible due to ping spiking and downloading files becomes extremely slow. If I unplug the Chromecast my internet speeds return to normal. I don't know what Chromecast is doing, but something is taking it's toll on my network.
Rebooting the router (Linksys E1000 I believe) has down nothing to resolve the issue. Does anyone know what could be causing this? Is there a way to make Chromecast hibernate or something when it's not in use? Any information about what could be causing the issue or things to try would be helpful. Thank you

Corrected the issue
I was able to fix the issue. Turns out my Cable Modem has a built in router that my computer was plugged into. I also have a linksys (wireless) router that is connected here. The chromecast is connected to the linksys router. I unplugged my computer from the cable modem (router) and plugged them into the same router as the Chromecast (Linksys). This appears to have fixed the issue. Someone that is better with this stuff could probably explain why, but I just wanted to follow up.

Totally!
I had this problem too. I have a Chromecast, AppleTV, GoogleTV and Ouya all right next to each other, with the Chromecast in an "always on" state. Ever since plugging in the Chromecast, network performance on the AppleTV and GoogleTV has been unusably slow. Even VNCing into my desktop PC, which is hard-wired into my cable modem, was slowed down.
I unplugged the power on the Chromecast last night, rebooted the AppleTV and GoogleTV and voila they work wonderfully. Network performance on other connected devices seems to be much better as well.
Would having several wifi devices in close physical proximity be the cause, or is it more likely Chromecast's need to be "discoverable"?
FWIW my wireless router is an Xfinity modem.

Can you describe what happens in a little more detail?
Does your network get slow, does your Internet get slow, do your devices suddenly say there is no wireless network? Something else??
"Unusable" can mean a lot of things.

My internet access on other devices becomes very slow to the point of being unusable if the Chromecast is plugged in.

It's slow - but it still works?
Hmm, Google says your RTN56U is compatible but to contact ASUS for assistance which I'm guessing means ASUS might have an beta or pre-release firmware that fixes the issue.

I'm having this same issue. I'm using an Asus rtn16 with tomato firmware by shibby. Quite frankly it's ridiculous that this is a problem for chromecast. My router is a newer model and it should be supported. My roku 3 is able to stream just fine off my WIFI. All I've been able to deduce thus far is that when casting, the wireless interface of my router seems to get ddosed in some way because when pinging the router wirelessly from other devices, the pings skyrocket up to 1000ms and it causes some packet loss. Ends up making the chromecast stream really badly and of course my other devices slow down. When pinging the router through a wired connection during this time, the pings are sub 1ms. So it seems that the chromecast wreaks havoc on the wireless interface for whatever reason. As I said before, no other devices in my home cause the same symptoms. I may try to see what I can gleam from sniffing the network with my alfa usb WIFI adapter which is able to capture everything going across the air in promiscuous mode. I'm not sure if a lower level wireless spectrum analyzer would be necessary but let's hope not. Or let's just hope Google gets this sorted! I realize that some have fixed this by switch routers, but I don't see that as an acceptable solution since no other devices have issues with my router.

Roku and Chromecast work in very different ways and therefore use the network in much different ways. Chromecast has a discovery protocol that Chromecast-enabled applications use to find Chromecasts on the network. This involves multicast packets, and while most routers handle and allow multicast just fine, some either are stupid/flawed or are shipped with "secured" default settings that block multicast traffic.
After discovery
What applications and content are you casting from?

Tried youtube, tab casting, and plex.
Youtube barely gets through a video. Tab casting works for a couple seconds, then chokes and loses the connection. Plex buffers every 5 seconds. I actually do notice ping rises to around 500ms when using plex on my galaxy note 8, when the client fetches chunks of video every 10 seconds or so from the server. i noticed that this happens over tcp, whereas tab casting sends a udp flood. but I'm not really sure what is 'normal' as far as the ping going up when the wifi is being used to capacity. I can imagine that saturating the network would do that. I know that plex will pull data in chunks as fast as it can. So that saturates the wifi for about a second or two for every chunk. But I guess for whatever reason, chromecast saturates it even more. Not sure if its because its udp or what, and I don't really know why that would make any difference.
So, streaming with anything else is ok, on both G & N modes, causing ping to go to around 500ms.
When streaming to CC, on both modes, ping can hit 3000ms at times and total packet loss.
I'll see if playing with any of the advanced wifi settings in the router can fix it.

Not sure this is relevant but I have seen a bunch of issues being reported by people using custom Router Firmware....
Not just here but on other sites as well...
Maybe it's just coincidence...

Your network bandwidth seems "bursty" - not a big deal for general data transfer, but definitely an issue for streaming where sustained throughput is important.
What's your signal strength on your Galaxy Note?
Can you increase the signal power on your router?
Also, check your router's orientation. Often times the internal antennae are designed to operate in specific orientations, so putting a router designed to stand upright on its side can drop the signal dramatically as the devices are no longer within the transmission cone/donut.

Chromecast can't connect to my router TL-WDR4300

Hi all,
I have a TP-Link TL-WDR4300 at home. My Chromecast is having issue connecting to this router. When i run through Chromecast setup, it goes fine up to the point where it asks me for password of my router. After I enter my password and click next, my TV would just say 'connecting...' and it will stuck forever. And the Chromecast setup app will say "Something went wrong. We weren't able to find your Chromecast on the network." Apparently because it wasn't able to connect to my network.
I'm pretty sure I have my password entered correctly. I tried to changed my router settings but it won't help at all.
One interesting thing is that my Chromecast used to be able to connect to my router before it was updated(which happened automatically when I connected Chromecast to my router for the last time). Although I had similar connection issues in the past, I was able to fix it by a combination of resetting Chromecast, rebooting router and changing router settings. Now, it just won't connect no matter what I do.
Any help is greatly appreciated!

I would reset everything and then try the setup program again if you haven't tried that already.

When you say "changing router settings", does this include channel width? Is it set to auto? Have you tried setting it to something manually, preferably 20MHz? Also what is your Network Mode set to?

Have you tried using the HDMI extender? That can help a lot in some circumstances. It's amazing how much a TV and other electronics will interfere with WiFi signals.

I never had problems with my old router. So I'm pretty sure it to be a compatibility issue.

I have the same exact router (TL-WDR4300 but running dd-wrt) and have zero issues connecting my 2 chromecasts to it.
One chromecast is running PwnedCast and the other is vanilla on the most current update. The router is running both 2.4 and 5 ghz and both chromecasts are connected to the 2.4 bandwidth.
I am using the extender on both.

Well does the Chromecast Light blink or is it solid?
If it is solid then it is connected to the router and you have some security setting or firewall either on the router or the PC isolating it from other devices.
Typical issue is when you have mis-selected Public for your network type in Windows instead of HOME,
Public isolates the Windows machine where HOME allows Device to Device communication.
Check the firewall settings on your router and try shutting it off and see if that works. If so then turn it back on and look for other settings like Multicast filtering or IGMP and uncheck.
If the light on the CCast is Blinking then it is not connected and you need to re-run the setup.
You say other devices are seeing it so thats probably not the case.

Update: It turns out this is not the root cause of this issue(refer to my post below), i will try dd-wrt next!
Thanks for the suggestions!
By following your advise and checking my security settings again. I was able to solve this issue by turning off VPN firewalls. I don't use any VPN thing so i thought the VPN firewalls wouldn't matter. Anyways, thank you very much and now I can enjoy Chromecast again!
However, there is one annoying thing. When casting from Chrome tabs, it won't go into full screen. There are black bars on top and bottom which isn't there if I cast from Youtube. I tried changing all the Chromecast extension options and Tv aspect ratio setting, but had no success. It would be awesome if you can offer some advice.
Thanks again!:good:

Go into Options of the Googlecast ext on your Browser
Select Full screen zoom and make sure it is enabled.
But there will always be some content that doesn't format the screen properly and will give you black bars...

Well, after all, it was too early to call it a success.
So earlier today, I wasn't able to discover Chromecast from my PC(It says something like "device missing" in Chromecast extension). However, my TV shows Chromecast is connected to my network, and the light on Chromecast is stable white. Then, I tried to reboot my router, and that fixed it. This is basically similar to the issues i had in the past where i could just fix Chromecast connection by randomly rebooting router and resetting Chromecast.
I was skeptical and decided to revert my changes on VPN firewalls. After a router reboot, Chromecast still worked!!
At this point, I don't think it's the VPN firewall settings that is causing this issue. This issue looks so random. I would try to go dd-wrt next and hopefully it will fix this issue properly.

Well, after all, it was too early to call it a success.
So earlier today, I wasn't able to discover Chromecast from my PC(It says something like "device missing" in Chromecast extension). However, my TV shows Chromecast is connected to my network, and the light on Chromecast is stable white. Then, I tried to reboot my router, and that fixed it.

You mention DD-Wrt are you using that?
Cause I notice most people having these issues seem to be using DD-WRT or Tomato and I'm starting to wonder if perhaps there is some issues with those Custom Firmwares being used.
I do know in the past before I Upgraded my router that I had problems with devices getting booted off the WiFi because I had too many devices connecting and it would seem that when a new device would connect, one would stop getting data despite the fact it said it was connected.
Now this shouldn't ever be the case with WiFi if it has an IP it should not have a limit but I am wondering if your experiencing what I was experiencing before I Upgraded....
Not suggesting you need to upgrade mind you just that what your going through sounds similar to what I went through.
When I bought the new router (LinkSys N900) the Box had this chart of Router Groups and which router was best for X number of devices.
Low end for less than 3, High end for 7+ with the last group being for 7+ and HD.
This chart went against what I believed I knew about WiFi limitations which I thought was only IP and DHCP based...
I wrote it off as pure Marketing with the intention of getting you to buy the most expensive router they had...(which I was going to do anyway LOL)
I'm starting to wonder if maybe there is something to that....Sure would explain my problems with the router that made me upgrade in the first place.

I'm having the same issues with my chromecast and a tp-link wdr4300 router on dd-wrt (latest build from 2014-02).
After either chromecast or router (wi-fi) restart I'm able to cast and chromecast is also shown in chromecast app.
But after some idling (without casting) chromecast is still connected to my wi-fi (ping responses) but I'm not able to cast anything (music, allcast etc..) anymore.
I have already tried enabling/disabling UPNP, changing wi-fi channels, etc
Doesn't look like just a wi-fi issue only, as chromecast is still connected to my wi-fi.
but still could this be related to the Atheros chipset used in the wdr4300 maybe?
Any other routers with atheros chipset running without problems?

Try installing Bonjour Browser or another mDNS browser and monitor what happens in local._googlecast._tcp
Also check router security and firewall logs to see if things are being blocked corresponding to when the mDNS broadcasts fall off.
Sent from a device with no keyboard. Please forgive typos, they may not be my own.

Seems to be good now for my setup.
I had installed a bonjour browser but couldn't see anything special.
local._googlecast._tcp was present all the time even though I couldn't cast.
I have changed the router firmware from dd-wrt (02-19-2014-r23598) to a self compiled OpenWrt (Barrier Breaker r39770).
I have been able to cast now stable for 4 days. Never had that before on dd-wrt.

Thanks for the update. Good to know that OpenWRT is working for you.

I have the same router. Don't recall having any issues on stock firmware. I'm on ddwrt now.
Did that as I plan on converting to extender when I move to the AC router soon.
I can only imagine the Chromecast didn't like something in your settings.

"Something went wrong. We weren't able to find your chromecast on the network"
[ this trick worked for me ] .. I had the same issue.. I was trying to connect my lcd remote monitor to my windows 7 pc. In the chromecast setup, I was able to go till the page that asked for the wifi network id and pw.., and later i got the error "Something went wrong. We weren't able to find your chromecast on the network" Many tries and all failed. Later i downloaded the chromecast app in my Android 5.0 smart phone and did the settings and voila! .. it got installed in the first try. Later without factory resetting the chromecast, i reinstalled the chromecast setup in my windows 7 and it got installed without any error. Later i opened up the chrome browser installed the chromecast plugin extension and it worked well. I was able to view my page on my remote monitor. Hope it works for u too..

Chromecast not seen on network since 16664 update

Since my Chromecast updated to 16664 (official) last week, I have had a bear of a time having any device see the Chromecast. Prior to the upgrade, I didn't have any issues with connectivity. Now the only way I can get the device to work is to do a reset to defaults and go through the setup procedure. The CC will generally work until the next power-up, then the same thing.
When this happens, the ChromeCast's home screen indicates it's connected to my WiFi network, however no Chromecast enabled program, including the Chromecast app on my phone, sees the device.
There have been no changes to my wireless network settings since it worked last. Given that I've not seen anyone else post about this, I must be the only one seeing the problem. Anyone?

I've seen some similar reports over at Plex but not here...
I myself am on 16664 and have no issues seeing my device.
try a Factory reset and see if reconnecting helps at all.

I've had a similar experience. My Galaxy SII and Galaxy tab 3 can see my Chromecast, but when I run the Chromecast app from my Kindle Fire HD, I get the message "No Chromecasts found on <network>". If I do a factory reset on the Chromecast, then the KFHD will find it, but once it's setup, I won't find it again. For me, the solution was to unplug my TiVo Premiere and TiVo Roamio from my network. Then the KFHD can find and cast to the Chromecast. But if either TiVo is connected to my network, the KFHD can't find the Chromecast. It's weird that this only affects the KFHD and not my other android devices.

TiVos use mDNS advertising for their services.
Recent Chromecast firmware also seems to be using mDNS as well.
Try running Bonjour Browser and see if Chromecast is visible before/after reset or reboot.

Not sure if related but it may help.
My router has 2 channels, 2.4ghz and 5ghz, the chromecast is connected to the 2.4ghz of course, the issue is when another device is also using the 2.4ghz it wont see the chromecast for some strange reason, the second I connect that device to the 5ghz network it will see it and everything will work flawlessly.

If your router has a WMM option, try toggling it - on some routers WMM implementation is broken and makes things worse when it tries to kick in and make your media streaming better.
Also, if you're streaming local content from another wireless device you may be exceeding the available bandwidth on the band - see WiFi Bandwidth and Router Considerations for diagrams on how the bandwidth usage can multiply depending on how content is being accessed.

Streaming is fine (using plex with pc as dlna) it's just a weird issue that used to happen, haven't noticed it in a while because our phones always connects to the 5ghz network. WMM is on so if it happens again I'll try playing it.
Also I doubt I'm even getting close to the wireless bandwidth cap.
Thanks for your reply tho!

Weird... Might also be a more general network thing like a rogue device with a static IP causing a collision that Chromecast doesn't gracefully recover from, or a multi-interfaced device causing some kind of loop
But yeah, since you have 5 GHz, best to use that and keep your 2.4 GHz usage to a minimum to maximize available bandwidth for Chromecast..

Let me try a few of the suggestions here. I've not had any luck using 2.4 or 5GHz bands on my network...behavior is the same. Also, my router is an ASUS router with Merlin firmware. There is a new thread I've only glanced over, but I'll try some of the things there as well:
http://forum.xda-developers.com/showthread.php?t=2599515
I had to do the factory reset trick again last night so we could watch video on the Chromecast...it obviously hasn't gotten annoying to the point where I'm stopping all other activity until I get it fixed, though. Strange this only started happening after the Chromecast update, but I can no longer remember the sequence of events that go me here (chromecast update, router update, wireless AP added for better wireless coverage, etc).

I've seen similar behavior when there are just too many devices connected to the WiFi at once.
My router maxes out at around 9-10 devices...
Doesn't matter which band they are on either.
But to be sure it isn't an IP conflict I suggest setting DHCP reservations for all your regularly connecting devices to ensure they never get a different IP (especially important to do for servers like Plex) and remove that possibility from the equation.
Just to Add I believe the new 802.11AC Standards solve this problem, But you will need to buy a new router to get it.

Using a bonjour browser, I can see the entry for the Chromecast :
_googlecast._tcp.local.
Bedroom.local.:8009
/192.168.254.193
st = 0
ve = 02
md = Chromecast
ic = /setup/icon.png

I'm running the browser that sees that from a Samsung tablet, which is also running the Chromecast setup app that says it can't find the Chromecast.
EDIT: I've tried the factory default recovery method a number of times now. I see the bonjour record go away, then come back after the setup app says I'm ready to cast. All apps can see the Chromecast at that time, then after 3 to 5 minutes, they no longer see the Chromecast. I don't see any difference in the bonjour record when it working from when it's not working.

Just a longshot....But do you have any security software that could be blocking some Apps from communicating with the Network?
It sounds an awful lot like what happens when an AntiVirus Application Monitor has denied access.

Hmm, No, I don't think so.
But I found something interesting. My laptop CAN see the Chromecast, and I can cast Chrome tabs just fine. So far it's only the Android devices that can't see the Chromecast (and at the same time the laptop can). I'm looking for my iPad (I don't use it enough to keep track of it as close as I should) to see if it sees the Chromecast or not.

That's really odd. Your network has only the ASUS router for wireless, no repeaters or extenders?

I do have an extender (not a wireless repeater) in place, but it didn't make any difference before the latest Chromecast update. My next step is to try removing the extender, but I don't know if the Chromecast will see the signal coming from the other side of the house (the reason the extender was put in to begin with).

It's quite possible that the update changed something about the WiFi connection that your network simply does not like. People have noted similar "introduced issues" with HDMI before. Definitely submit a report with them if you haven't already, and request that updates NOT be forced to avoid issues like this. Being able to dismiss, postpone or even roll back an update would prevent this type of thing.
If it's not the build, I'm not sure what else it might be, unless your router has somehow quarantined your other Android devices on another band or SSID somehow.

Looks like I switched off TKIP and just went AES on that network at some time. I went back and turned on AES+TKIP and now the Chromecast shows up on my mobile devices again. I'll keep an eye out in case that theory doesn't hold out.

Unable to cast netflix

I used to use the netflix on daily basis until about three weeks ago I started to get the following message after a long time displaying the netflix splash screen on my TV: "Humm... It seems we're unable to connect". And then the netflix closes after 10 seconds. Every other chromecast official app works good, but Netflix. I also noted that if I restore the chromecast and launch netflix, everything will work. But if I cast other app, as YouTube for instance, and then return to netflix, I'll get the problem again, requiring another restore.
My chromecast software version is 16664.
Is anyone experiencing the something like that?

Just to confirm, you're not using any DNS relocation/redirection (Unlocator, Unotelly, etc), right?
I just used Netflix the other day, and I'm still on 16664.
It's weird that everything else works except for Netflix, and also weird that factory reset makes it work. Could be a bug or perhaps something with WiFi connectivity. You don't have a WiFi repeater or multiple APs using the same SSID do you?

I use regular DNS. I also tried different WiFi routers and I always got this issue. Rarely Netflix works without need factory reset.
I was wondering if it could be a problem with the chromecast cache. Do you know a way to clear the cache without factory reseting?

Not that I know of... however, since the Netflix app is stored on Chromecast, there's a small possibility that it's a RAM or NAND issue on your Chromecast itself. If it's not rooted or special in any way, you might want to consider getting it replaced.
Or see if you can borrow another Chromecast to see if the problem is localized to your specific device.

This is new for me. I thought Netflix was loaded online. I'll ask a friend that has chromecast to test mine in his home and and borrow his chromecast.
I'll let you know the results tomorrow.
Thanks

I borrowed a chromecast and first time it worked. After casting YouTube videos and then return to netflix, same thing happened. My friend got everything working great using my chromecast.
The only thing that never changed is my cable modem, but I never change anything on it. Moreover, why this is happening only with netflix and why it works if I factory reset are still a mystery.

Perhaps you are seeing the first case of Net Neutrality biting you in the ISP?
See if you can reach Netflix via the browser...

I don't think so. I can access netflix anywhere else: tablet, phone, ps3 and computer. Besides, my friend use the same isp.
The only other place I having trouble in access netflix is my old Asus cube that I had retired since I got the chromecast last year.

Quite the puzzle...
Since your Chromecast works on your friend's network, and your friend's Chromecast shows the same behavior as yours on your network, the breakage factor definitely seems to be something about your network.
I really can't think of your cable modem being an issue unless isn't going bad (if it has an interface, look for excessive errors and/or poor signal quality - for example, Motorola SurfBoards usually have an interface at http://192.168.100.1/).
As your friend is using the same ISP, I would compare your router settings with his - ISP login type, routing and DNS in particular.
Of course if you have different routers then the router itself is still a variable.

I'll try to share my mobile Internet connection as soon I get back home to see if it will do the same.
Also I'll try to look the router log to see something.

I tested chromecast connecting to my phone in tethering mode. Netflix worked everytime. But when I got back to my regular connection, the problem appeared again.
So the problem seems to be located in my cable modem that also is a router.

Ok first question...do you have another router connected to the Modem Router? Are you using the Modem's built in WiFi or this other router's?
If you have another router then chances are likely you have a double NAT situation which is messing you up.
Check your other router and see what IP address is has listed under Internet connection...If it is a 192.168.xxx.xxx then it's a double Nat and you need to call your Cable company and have them put the Modem into Bridge mode.
If you do not have another router and use only the Modem router then you need to call the cable company and have them change the settings on the router to allow multicast and UPnP...Maybe a few other settings as well. Tell them what you are trying to do they have probably gotten lots of calls from others with the same issue.
Me personally I prefer to use my own router and have them put the Modem into Bridge mode so I have full control over the network and don't need to call them whenever I have a problem or want to change settings.

My cable modem a public IP provided by my ISP, and a private IP that is 192.168.0.1. My router has a WAN IP provided by my cable modem (192.168.0.xxx) and a LAN IP 192.168.1.1. My chromecast used to be connected in my router LAN, but I changed it to connect directly to the cable modem router. I'll try to put the cable modem in bridge mode to see what happens as I have full access to its configuration.
Thanks again

Yep that setup causes a double Nat situation Which doesn't work well for most networking applications....
Especially since you are also dealing with Two different Wireless networks.
Best setup is to have the modem just be a modem and send public IPs to whatever connects to it.
Then you won't have any Nat translation issues PLUS you get the ability (if your Modem has multiple ports like most Modem/Router Hybrids do, You can get a public IP for any device directly connected to the Modem which is good for running servers and for testing router issues.

Problem solved!
I turned off the wifi on the cable modem and put it on bridge mode, letting my router deal with my network. Netflix is now working good on both chromecast and Google tv.
However I believe the problem was related to a still unknown setting in the cable modem as I left it operating alone and netflix was still not able to load.
Thank you very much for the help. I really appreciate it.

it may very well have been a Router issue with the Modem...But now that it is only a Bridge the other router's settings will handle all the communication needed for the CCast and it should work...
As long as the settings on the second router were not the issue in the first place.
