Chromecast not showing up on PC?

So I purchased a Chromecast yesterday and set up was perfect. I set it up using my Macbook Pro though, which of course was connected through WiFi.. I can stream to it fine from that macbook pro, my iPhones, iPads, etc, but I can not stream to it from my desktop PC which is plugged directly into my N600 Router? I have installed the Chromecast Extension and everything but when I click on it, it says No Cast Devices Found...
Anyone know why? I haven't really messed with the router settings but could it be something wrong there?

I have a similar problem. Would like to find a solution.

We really need a FAQ, 'cause this is about 15% of the posts here.
You need to, on your router, disable the block between devices seeing eachother, or between wireless seeing the wired side, etc.
It might be "isolation", or require toggling the IGMP setting, or whatever else it is or isn't your router doing, but that is where to look. Check it's settings, review it's help files, there you'll find the answer for your brand/model/version router.

I'd like to agree that this is the problem those 15% of posts have... but that isn't the case. I have a chromebook pixel that see's the chromecast just fine with the chrome extension, but a windows laptop that does not(tried both Windows 7 and Windows 8). Any other ideas?

Well, I talked to Netgear about the issue and they said they didn't even know what a Chromecast was.. I finally got them to understand what it was and what it does and we looked over all the settings on my N600 which were all correct.. We even reset the router to factory just to see and nothing..
After getting off the phone with them, I decided to try reinstalling the drivers for my built in Nvidia Network card. I went to device manager, deleted my network card, rebooted windows, it reinstalled the default drivers for it and waalaa that fixed it.
So as to the 15%, it may not be your router, it could also be your built in nic card or even your firewall/antivirus

You can NOT use the desktop application on a wired connection. The browser plug-in should work without a problem, allowing you to use the device normally.
The desktop app is only really used for initial setup/maintenance. It requires you to be on wireless because initial setup relies on a temporary ad-hoc connection being established.

Glad you got it to work.. I am little bit concerned that it is perhaps an incompatibility with certain WiFi adapters since in my case I am using two different windows installations on the same computer(thus different drivers, antivirus etc..). That said the computer worked fine for the initial chromecast setup, just not with the extension.

Its not the desktop app I am using. It is the chrome extension

I had this problem yesterday, i just unplugged the power from the CC and plugged it back in and that cleared it up.

Now this seems like it makes sense. I can ping between all devices but just because pinging can make it doesn't necessarily mean that the ports necessary for Casting can make it.
I have Verizon FiOS. Here's a screenshot of the only IGMP settings on the entire thing. I'm sure what's supposed to be on or off or whatever. If anyone has any insight - please do share.

I struggled for hours trying to figure this out. I even nuked my Chrome installation.
Disabling IGMP in that exact settings box worked.

PERFECT.
Thanks Omega for the direction here.
To clarify, those of you who have Chromecast working properly on other devices but cannot connect through a WIRED/ETHERNET pc, you should look in your router settings for anything relating to IGMP and DISABLE it.
After disabling, I rebooted my router. Once Chromecast reconnected my Chrome browser saw the Chromecast device and could cast perfectly.
Hope this helps! Good luck!

No problem, thank you for pointing it out. I was almost positive it wasn't the router because I found sources where it said that the Verizon Actiontech routers didn't have AP Isolation or didn't support it or whatever. I was so fixated on my Chrome installation after that because I've been having Remote Desktop issues which I thought might have been running off a similar service that Chromecast did or something weird like that.
Works like a charm now.

Making Rooted safer than Stock

Dear Team Eureka there is one thing you may do with security of Chromecast that Google did not.
You may add the missing security feature:
"if there is no connection to preset network" - "do not enable unprotected wifi ap mode" unless user will press reset button for short time (something like enable/disable wifi feature with openwrt)
There is plenty of things you ma use button for in future
(you may use different functions within different interval)
press
1-5 seconds
6- 15... and so on

I like this feature!

I agree that the way it is currently working is not as secure as it could be...
But I think the better way to do all of this is the following:
1 - Never have the CCast automatically connect to an Open Wireless unless specifically told to via Setup (not sure if it does this now or not)
2 - (and this would be the alternative to your suggestion) CCast doesn't leave any unprotected network sans AP connection for setup. It's default setup mode is a protected WiFi either WEP or WPA
CCast should instead set a random pin/pass and WPA/WEP connection for use in setup when it can't find an authorized AP.
Since you should have access to the screen it is plugged into and hackers would not, you would make the connection to the CCast in protected mode using the PIN that is displayed on the screen to make the connection to the protected network. Once connected you set up the device normally.
Much better than walking over to the TV and device to press a button and much more secure because the only way to set up or take over the unit requires access to the TV it is plugged into.
As far as the Button is concerned I would really like to see it used to switch modes and add a DLNA device mode to the custom rom. Unless the ROM could add this feature while still in CCast mode.

AFAIK Chromecast never does #1 - it won't auto-connect to any AP unless it's already set up.
Agree on #2 though. Actually, both yours and mathorv's suggestion could be used in conjunction - Chromecast should use WEP security* on its setup AP and turning on the setup AP could be set to require human interaction.
*mainly for compatibility with clients/routers that don't support WPA or better - yes, they still exist - crackable, yes, but still better than completely open as it is now.
Since the serial number is easily accessible on the unit itself and its box, that could be an easy-to-get password, and the 4-character alphanumeric ID shown on the TV could be a secondary confirmation for Setup, not just a convenient way to make sure you're connected to the correct Chromecast (does Google really think/hope there will be that many Chromecasts out there being set up at the same time?).

Also if http will be protected with https also passwords it may be better to config Chromecast wireless options via https/ssh.
Is there any way to implement power save for example trigger via ssh/https?

Thats why I think whenever it can't find an AP to connect to it shouldn't take anything for it to generate a random password (changes everytime) that can be used until setup is complete...
As for HTTP access i it is not connected to an AP there really is no HTTP available until you have connected to it in some way.
I would be happy if Google allowed us some config tools but I don't think they are all that interested in us having control over the unit for DRM purposes.
The devs at Plex have even said that Google will not allow them to implement sending to CCast as part of their Local PlexWeb (Plex.TV is fine though)
This suggests they really do not want anything they can't approve or any usage that could expose how the device is talked to being left open to the public.
I guess they figure that if we can see how linkage and communication is done we will reverse engineer it to play and do things they don't want us doing or bypassing DRM schemes as they currently work.

WEP is broken for over 10 years now! No sane human being is using it. Cracking WEP is extremely fast and easy. WEP is a false protection, illlusion of security. Using WEP is BLASHEMY.

Obviously you feel strongly about WEP.
I'm not going to argue that, because you are right that WEP is easily broken. WPA can be broken too, but with more effort.
That said, WEP is an illusion of security only if you expect it to be unbreakable, just like passwords and everything else.
Seat belts won't save you in every accident, but if you don't expect them to, they are still helpful in the event of an accident.
Now if you're driving recklessly because you think seat belts and air bags will save you, then yes it is a false sense of security and you're foolish to take extra risks.
But for the Chromecast setup AP that is temporary by nature, are you suggesting that it is better to not use any security at all, just as it is right now?

You know what I always say.....
"Just because you are Diagnosed Paranoid doesn't mean people aren't out to get you!"
LOL
This is the second conversation regarding CCast vulnerability and so far all we have identified as a REAL security concern is that someone could set up the CCast to connect to some WiFi other than yours which would lead to the grand total tragedy that they could send content to your TV.
The other conversation was in regards to the Rooted ROM having SSH and Telnet installed that could be used to hack your Router Password provided you had already hacked the router password to make the connection to the CCast in the first place to use those tools to get what you already have!
Here is something folks should take into account....NOTHING IS SECURE EVER!
Even the Servers in Iran's Nuke Plant that had no connection to the outside world whatsoever were compromised, Hacked and attacked by Stuxnet!
There is no security ever the only thing you can ever really do is make the hack hard enough and as time consuming as possible that they will move onto someone else's system to pry into their Word Docs and that private folder you keep your IFriends profile pictures in instead. LOL
Yes WEP can be hacked. Imagine how much fun someone will have after they set up your CCast to use their network and try to send content to a TV never knowing if you actually noticed it or not because they can't see your TV.
It's still a damn site better than leaving an Open WiFi AP on the CCast until setup which takes no hacking skill at all to crack.
The way I look at it if the person is smart enough to hack they are also smart enough to know there is no point in hacking a CCast...Not when there is a WiFi router that gets them a hell of a lot more personal info and much more access than just displaying content to your TV.

While this would be a great dorm prank, at least with the current functionality of Chromecast, that's all they get to do... turn on the TV and send whatever video to the TV they want, which would be quite scary/annoying. Think of the beginning of Back to the Future Part II where all the screens in the house turn on with Marty's boss telling him he's fired.

Actually I think the scenario @mathorv described is a little different and easy to exploit.
Chromecast is in setup mode and broadcasting an open AP
Attacker connects to the open AP
Attacker connects to Web Panel and enables ADB/Telnet/SSH (because web panel currently does not require authentication, Team Eureka said authentication is coming)
Attacker connects to Chromecast via ADB, Telnet, or SSH and gets access to the root filesystem, where they can see the cleartext password and SSID of the AP that Chromecast normally connects to (because password is stored in supplicant config file which is accessible)
So the attacker does not need anything more than to see the Chromecastnnnn AP.
Sadly, the WPA authentication seems to be stored the same way on phones/tablets as well. The only thing that shields phones/tablets from the same type of attack is not all of them have root and they usually aren't accessible from the network. Hence, with root comes extra responsibility, which is why root often is made difficult.

Yup. What we commonly call "security" is really just a deterrent. It increases the effort and the hope is that the attacker will pick an easier target. It's why we put locks on doors when it's often relatively simple to bypass them.

Except for the fact that if it is not connected to the router then that means the router is unavailable, and or the Password saved in cleartext isn't working. If it was it would be connected and not in Setup mode.
Thats the point I was trying to get across there....
Sure you could find passwords to APs the CCast was connected to...
But if it isn't connected at the time of the hack then those APs are not available if they were you would not be able to connect to the CCast.
And if they are available then anything saved in the CCast is worthless since the CCast couldn't use it to connect either.
And I told him how to plug that hole far better than via the ROM....
Turn on Mac Filtering so not only do you need the password but need to clone a MAC address as well.
And all of this to get at what?
Your last will and testament and some compromising Pictures?
If you make it difficult enough that the payoff isn't worth the effort they will move on....

Ahh, I see your point now.
At least for me, sometimes Chromecast will "miss" the connection shortly after boot, so the setup AP is available for a few minutes after a reboot. To exploit that, someone would need to be sitting and listening for it to pop up - not a "juicy" target, but still possible. People do strange things "just because they can" - at least that's what YouTube teaches me.
As you say, MAC filtering provides an additional deterrent level. Unfortunately the target customer is probably not sophisticated enough to do that. I'm not sure all ISP-provided devices (I avoid integrated hardware that I can't configure) allows setting MAC restrictions though.

Well, in theory, you could connect to the CCast when it is in unprotected AP mode, enable ssh, and write a shell script which gets started every boot and sends out the saved wifi password somewhere to the internet. Then, when the CCast owner sets up is wifi, and sometimes later reboots, the wifi passwords will be sent out.
But... since there are probably only a few thousand rooted Chromecasts, and the time window in which to push the script to the Chromecast is so narrow, I doubt anyone would spend any time to try this.

I'm sure thats true but if your not sophisticated enough to control your own Network or let an ISP do it all for you the least of your issues are what might happen in the odd chance CCast is disconnected or in the 30 seconds before it connects to an AP during Bootup. Locking up the holes in a CCast sure isn't going to help you much LOL

What is the PAYOFF in the end?
I could understand it if your living next to Bill Gates and wanted to steal banking info....
The Average Joe doesn't have anything worth seeing that would make someone go through all of that especially when they could get it much easier by just sniffing WiFi packets and finding the same data and decrypting it.
They could sit there all day and hack the Router but they have such a small window to work with on an unconnected CCast either because they have to catch it rebooting or catch it in a location that it isn't setup for and unless you have written a program to do all of that without Human Intervention you still got a snowballs chance in hell of getting any worthwhile information...
Security only happens when there are multiple layers of protection that make it so difficult to breach that they won't bother unless the payoff is worth it.
Someone really has to hate you in order to go through all that so some of the best security practices you can implement is don't be an AZZ and no one will have it out for you enough to want to get something on you via a Hack! LOL

Actually I think what I was trying to say is that no matter how much you care and try to be secure...
If they want you they WILL get you and they don't need nor would they do it through your CCast when there are far better tried and true methods to attack a wireless router directly that doesn't require LUCK of a device not connecting or the timing of catching it while it is booting up in order to catch the weakness.
Any security hole that results from the CCast will likely never amount to anything more than the Prankish "Look what dirtyPorn I put on your screen"
If they want dirt they will go to the router which is always up and doesn't require some act of god or electronics to happen.
You secure your router the best you can and if that isn't enough then you need to keep your wireless off until you need it to be TRULY secure....
And even then there is nothing to stop them from tapping into the pole where your Internet connection comes in and getting you that way!
Security is nothing more than an illusion and a deterrent...Truth is your never secure no matter how much you worry which says to me...Worrying is pointless. Unless you have enemies that really want to get you...and if thats the case all the security in the world won't stop them!

MAC access list = joke, blacklist is also a illusion changing MAC address(spoofing MAC) is extremely easy on any platform.
In case of whitelist Attacker will look into it just a bit for a longer, to know list of allowed devices.
At home you will have to whitelist every new device...
In corporate environment it will take you more time also WPA2-PSK is not suitable for serous corporate use.
About absolute security.
Security is relative term. Its just like healthy life style, it will not make you immune to diseases, it will make you generally healthier, less likely to get ill.

Dropped connection

This is sort-of OT from Chromecast talk but DLNA is mentioned lots.
At a relative's home which is on Comacst Xfinity. Two weeks ago while there, I'm on Android tab while another are on a Chromebook and both are losing internet connection. I'm using Chrome and I get a page reload error. WiFi shows still connected but turning it off/on fixes it. So there is me, Chromebook and a iPod running in the home.
Yesterday, same thing happens again! Later I'm casting a video from my tab using BubbleUPnP to a DLNA TV. The Chromebook is on and I'm using Chrome. I get the reload page and a bit later the video stops. Get it running again, it runs for 45 minutes, Chromebook is off, my tab is in sleep mode but minutes after the Chromebook is powered up the video stops. We gave up after that.
One might think it's a WiFi bandwidth issue, correct? The catch is at home on U-verse, my tab alone and I get the same reload page error while using Chrome. Wondering if this is a Google problem with WiFi since a Chromebook is nothing but Google Chrome like I'm using on my tab?? My tab has been on the same ROM version since last October.

I don't think the ISP is involved here at all, it's more likely that you have too many wireless devices connected at the same time for one Router to handle...
While Technically and theoretically it should handle up to 250 devices, real world experience says anything more than 7 or 8 wireless devices and you start having issues with connecting to the router and Internet access.
Thats probably not true for all routers but very true for the cheaper ones.

I would agree if it weren't for the fact at home it does the same thing. Hmmm, I was going to say just one device connected but at home but the TV has a Chromecast and a WiFi adapter as well so it's three devices.

Well at home your TV is probably interfering with your CCast. If possible try wiring the TV.
Also make sure to use the extension cable that came with the CCast.
Your TV has WiFi which suggests to me it is a smart tv...
Try looking to see if there are apps for it that can do what the CCast does like make it a DLNA target or has a companion app (like Plex) to do your streaming with.

No, the problem I have at home similar to what I had at the relatives home is not while casting, it's just a loss of internet connection. Turning WiFi off/on brings the connection back.
During casting via DLNA at the relative's home, it "appears" the additional use of the Chromebook caused the video to stop and the TV goes back to normal TV programming.

Check the router for WMM settings - sometimes the WMM implementation is broken.
It can also be a buggy router... I once had a Netgear that was fine for regular use, but if I tried to do a large file transfer or otherwise put load on it, it would crash and require a reboot. It didn't last in my setup for long.

No such settings in my Gateway(router).
This is the same problem in two different home, one Comcast and the other U-verse.
I'm on U-verse just watching a normal broadcast TV channel while on my tab using Chrome and it stops working. I've cast a whole movie to the Chromecast without a single stoppage, of course I'm not using Chrome at that time.

Sounds like your Chrome has become malicious somehow. Try starting it in Safe mode without extensions and see if it still causes problems.

This is Chrome for Android and not the latest Beta version. I'm not 100% sure but I don't think I had this issue using Dolphin before switching. I had to force myself to use Chrome but I'm used to it now.

Try Clear Data on it? Not much else, unless some page that's syncing over is doing some massive network test or something.

Remember that the Chromebook was having a connection issue at the same time and this is in a different home, different system and different router.
Whatever turning WiFi off/on does makes it reconnect on the first try.
I think the Chrome page that come up with two options: more and reload. I turn WiFi off/on, go back, tap on reload and it loads the page.

But it's the same Google login on Chrome, right? I'm thinking that the "have your tabs on any device" might somehow be involved.
Seems Chrome is the only common thing, so it's either related to the login, or Chrome itself is busted.
If it's the latter, I'd try installing the beta (it can live alongside regular Chrome) and see ... maybe it'll play better.

There was a Chromecast there but wasn't powered as it's on another TV. Unless it was changed, it was always powered up but kids turned the TV and crack the plastic. I understand that it works loose.
I've pulled the power on my Chromecast and pulled the WiFi adapter to see if I still lose internet connection.

Only thing I can think of is, at least on my phone, in the Advanced WiFi settings there is an option to check for Internet connectivity. When that setting is enabled, the device tries to detect Internet via some method, and if it doesn't think there's connectivity it'll disconnect from the AP and switch to another if available or drop back to mobile network if available.
Perhaps the streaming (or something else) is interrupting the Internet detection long enough for it to think it's not connected, so it disconnects from the AP and tries to connect to something else - or just gives up.

There's no option like that on my tab. I'll have to ask my Bro-in-Law if his Chromebook has the same issue when he is home also but I'm not sure if it's used a lot. I'm going to go back to Dolphin tonight to see if it does the same thing too.

Hmm, just checked my JB 4.3 phone and the option seems to have disappeared.
I swear there was an option in the Advanced menu of Wi-Fi settings in 4.2 or 4.1.2
I'll have to check my wife's phone that's still on 4.1.2
Okay, I'm not crazy. The setting was in Advanced options of Wi-Fi settings and was called "Check for Internet service"
It might be a Samsung thing, but regardless it is gone in 4.3, but existed prior in Galaxy S3 and S4 at least...

I installed the Chrome Beta for Android last night but it did pass the bookmarks but password info didn't/doesn't transfer with them. I got annoyed and uninstalled it!
I found a app called WiFi Fixer which describes the problem exactly(WiFi stays connected but data isn't transferred) so I installed it and will give it a try tonight.

Could not setup Chromecast after factory reset

Hello,
I decided to reset my Chromecast because none of my devices recognised my Chromecast.
So I did an factory reset, but when I set my Chromecast up again it can't communicate with my Chromecast for some reason.
It looks like the last step to connect with my WiFi router is the problem, but I don't know.
How to fix this?

What are the exact messages you're getting?

"Could not communicate with your Chromecast"

This is from the Chromecast setup app, yes?
What does the TV screen show?
The Chromecast setup app has never been 100% reliable for me... The last time I factory reset I had to run through setup 2 or 3 times before it applied properly.
You may want to try the manual setup instead.

+1 also try setup from a different device if you have one. (Laptop, tablet , PC)

One other thing to try is to disconnect from your AP before you try and connect to the CCast.
It is possible on some devices and versions of Android that being connected to an AP interferes with finding and connecting to the CCast AP.

Go into the app settings and clear the data. I had problems during a setup as well and that fixed the problem.

I managed to set it up with an iPad. But it's still not recognisable.

You don't have your 5 GHz and 2.4 GHz bands using the same SSID, do you?

Sorry I didn't answered your question, I was on holiday for a week.
I think our router has only 2.4GHz band.
I made some screenshots, maybe it can help, don't know.

What's shown on the bottom right of the Chromecast desktop screen?

It used to show the SSID of the AP it's connected to, but I can't remember offhand if it still does in the newer (build 14xxx onward) desktop display.

Yes thank you. Something seems wrong though... It's like the device is in a "half" set up state... It doesn't think it needs to be set up, yet isn't connected to wireless.
I would factory reset it again using the button. Maybe the first reset didn't completely reset somehow.

Thanks a lot! I manually reset the Chromecast manually with the button as you said and set it up again. It works now.

A little late here but I can confirm that My Ccast IS connected and yet does not show the SSID or indicate it is connected in anyway on the default screen.
It does indicate when it is in the process of connecting and for some time after it connects but after awhile that indication goes away.
I suspect it has to do with how many pics have changed.
What it does do though is indicate when it does NOT have a connection.
Which wouldn't help you if it managed to connect to the wrong router.

Problems are back again... Today I switched my Chromecast in another TV (Philips), again he saw no network, not recognisable. So resetted my Chromecast again but I can't get trough the setup process now, so I keep trying right now.
Edit:
Do you think to buy a new Chromecast to solve the problem?

Chromecast WiFi Range

I happened to look at the Chromecast app since it updated yesterday and there was another CC showing but needed setup. Considering problems some have had with WiFi reception including myself, I find this odd that I'm seeing one of my neighbor's CC.

Not odd at all...
It might appear as if it needs setting up but that is really only indicating that it is not on your local WiFi but could be connected to another.
Doesn't mean you couldn't hijack it if you wanted to however.

Well, I see a bunch of routers but they are known to be a bit more robust in WiFi signal strength compared to a CC.

Yeah but as long as there is nothing to interfere with the radio signal you can see lots of things...Connecting to them may be problematical but seeing them is almost always possible even as far away as a Quarter mile in an area that doesn't have a lot of RF signals floating around.

We are talking about the range of a CC not a router here. I talked to both of my closet neighbors and one does have a CC but I can't see his. Subdivision of single family brick ranchs at around 1100-1200 sq/ft on stacked 60ft x 100ft lots.

Check if it's your CC by unplugging it and scanning again. One of mine once booted up in a mode where it was simultaneously connected to my network and broadcasting its setup AP. It was the weirdest thing and hasn't happen since, but my Chromecasts pretty much never reboot unless I tell them to.

The rogue showed up while both of mine were off in the late afternoon yesterday and is showing up right now "Ready to Setup". Persistent little bugger, I had to kill the app as it keeps popping up to set it up! It has a off color name very close to a female sexual play toy.

What makes you think it shouldn't be able to? If it is ready for setup then you should be able to....
What may be happening is the router to which that belongs to is off or they are using a mobile hotspot for their internet in which case when the router leaves the CCast goes into setup.

I'm assuming that it just shows ready to setup because it's not setup on my network.
Presently it's showing up again so I tried to set it up and got "Could not connect to your Chromecast. Make sure your Chromecast is nearby".

Wait a minute! Yesterday, I think, I tried and got the "Do you see this number", have to try a few more times.

Actually I'm not entirely sure on this (Have not tested it)
But I'm pretty certain that it says "ready to set up" even when connected to an AP when it is not connected to the same AP as you!
And it makes sense that it does just in case the Ccast somehow connects to the wrong AP or an Open one that isn't yours.
So the App sees the CCast and can set it up. You may not be able to connect to it via the WiFi in AP mode, but you probably can still send it a setup command if it is in range via the App.
Not much different than telling it to load an App really.

No, you can't see a Chromecast that is connected to a different AP from what you're connected to, at least not when everything is working as it should...
Not configured, Not connected
Chromecast goes into setup mode as an open wireless access point named Chromecast#### (some 4-digit number)
Not configured, Connected
This should not be possible. Really.
Configured, Not connected
Chromecast goes into setup mode as an open wireless access point named Chromecast#### (some 4-digit number)
Configured, Connected
Chromecast is in normal mode as a wireless client
However, as I noted, I did have one instance where Chromecast was configured, and was connected, but still broadcasted its setup AP. I really should have investigated more, but I was freaked out and rebooted it - and things were normal after that.

I tried a few more times and once I had a popup stating that I was trying to connect to another router not mine. I know by the default name that it's another AT&T Uverse RG as the name is always 2WIRExxxx. I even tried going back to the previous version of the Chromecast app version but nothing changed. I'm using WiFi Fixer app and tried disabling it as well thinking that it may interfere some how.
One try locked my tablet up.
