I'm trying to connect my chrome cast to my wireless AP. I get the error message "We weren't able to discover your Chromecast on the network"
I've read that AP isolation is the problem, but I'm pretty sure that isn't enabled. And if it is, I have no way of disabling it.
I have a dlink DGL-4500 and a DAP-1360 running in parallel. Same ssid, same password, same channel. It's a seamless transition from one to the other when I walk from one to the other. I can even stream video with no problems.
Chromecast won't connect to my AP. I don't have wlan partition enabled. I don't have igmp snooping enabled.
I do have wmm enabled.

Have you tried turning one of them off to verify? Also are you running on 2.4, 5 ghz or dualband? I'm using cisco/linksys setup with a repeater (regular router on ddwrt) but they all have different ssids(3 total) and I know it works between them except obviously the chromecast won't connect to the 5ghz one.

I only use 2.4GHz. the DGL-4500 is either/or.
I've turned off the wireless on the AP, but the range of the router is too far away to connect.
I tried it directly on the DGL-4500 and it worked the first time. Then half-way through a movie, my phone refused to find the chromecast device again. I had to do a hard reset.
I can find no setting for AP isolation on the DGL-4500. Does anyone else have this router and having it working with an AP?

Make sure WLAN partition is off.
My settings finally were 20MHz single channel, WPA2 PSK, Mixed BGN.
My network is hybrid. I've got the DGL-4500 as the main router. I've got another Linksys WRT120Nish as an AP (which the chromecast is actually connected to at the moment and I've got the DAP-1360 setup in repeater mode in the middle.
I got a Chromecast yesterday. Still not able to connect. I am running setup on my Nook HD+ running CM10.1. I can't run setup on my laptop because it's wired and wifi is dead. Setup sees my Chromecast and I get "Now let's connect Chromecast2460 to your wireless network". I press setup and it searches. The 4 character code appears on the TV, then I get the error "Could not connect to your Chromecast".
Here are my router settings based on suggestions I've read.

Mine only started working once I'd turned AP Isolation off on my Netgear router. Then the install worked, network set up wise.
I do have a problem with my Toshiba 37X3030D TV - whatever I try to cast, I get a static blue screen. But that's another story!

After trying many things and wasting much time, I tried my Linux laptop and it WORKED! The Chromium page suggested I use a different device and I had to change wifi access manually to and from the Chromecast device. I'm sure my Windows laptop would have worked, Damn Toshiba. I dread sending it in so they can replace the wifi card under warranty.

I took delivery if a Chromecast today and the setup is a breeze. As I'm in Europe I have changed some settings in order to access the American version of Netflix because if the extended selection of films and series. It runs fine on my Galaxy Note 8, iMac, and Xperia Z1. But it can't run on my TV. Every time I try to cast a film on it I get this error: "Whoops, something went wrong...Device Messaging Error. There was an unrecoverable error on your computer. Please reload the page to resume controlling your device."
I have done some searches and found various possible solutions, but none worked. This is what I've tried:
- Signed out of all devices in Netflix.
- Reset the Chromecast.
- Disabled WWM on the router.
I doubt it's an issue with Netflix as it works fine on all devices except on the TV. Sometimes I do see there is an error on my iMac saying that Microsoft Silverlight has crashed but that doesn't seem to affect anything. Is there anything else I could do to troubleshoot?

Please tell us...
What make/model router do you have?
Can you describe how you "changed some settings" to access US Netflix?
Do YouTube and other services work?
If you use your normal DNS settings and access your local Netflix, does it work okay?
Chromecast is its own device and does its own DNS lookups and Internet requests after receiving the "go play this video" request, so if you're redirecting DNS on specific IPs/devices (rather than everything on your network), then you need to be sure the Chromecast IP/device is being redirected.
Otherwise your phone/tablet/computer is in Mens and Chromecast is in the Ladies and...
Phone/tablet/computer: "Excuse me, could you get my phone next to the urinal?"
Chromecast: "What's a urinal??"

Thanks for your reply.
The router is a Cisco EPC3925.
I used the instructions from the Unblock-us website. Changed the DNS settings to 208.122.23.23 and 208.122.23.22 as instructed. But I also changed the DNS settings to that on the Cisco router - otherwise the US material would not show on my tablet and phone (only on the iMac).
YouTube and Plex work just fine when casting material to the TV.
When using the normal DNS settings from the local Netflix it works fine.

Thanks for the info.
Seems like your core problem is that by default Chromecast uses the Google DNS servers regardless of what DHCP provides, so even though you've set your router so all its DHCP clients are being told to use the Unblock-us DNS, Chromecast still isn't. So all your devices are in the Mens, with the exception of Chromecast, which still goes to the Ladies, even though you tell it go to the Mens, thus it responds with "What's a urinal??" when you reference things in the Mens (US stuff).
Chromecast will fall back to using the DHCP-supplied DNS server(s) only if it doesn't get a response from Google's DNS.
Normally the ways around this would be to:
Route Google DNS requests to a bogus/non-existent gateway
Block Google DNS requests entirely
so Chromecast does not get a response from Google's DNS. Which one works depends on how your router handles the blocking/forwarding. You want a timeout or destination unreachable, rather than an outright refusal.
But... I looked in the manual for your router (seems to be a VoIP+modem+router combo) and unfortunately I couldn't find any way to add a static route, nor did I find a way to block or forward requests specifically for Google DNS.
So unless the ability to add static routes or the ability to block port requests for specific WAN destinations has been added, you may be a bit stuck. Definitely check through your router's config to see though, often times the manual lags far behind the current feature set.
However, if you don't have the necessary options in your router, that leaves you with these possibilities:
Add a router that can provide blocking or redirection via one of
static routes
IP-specific port-blocking
iptables rules
to provide network to Chromecast and devices controlling Chromecast (they need to be on the same subnet).
VPN - which is beyond my area of expertise for this usage.
Get a rooted Chromecast so you can use Eureka-ROM to enable use of DHCP-supplied DNS rather than Google DNS
If you go with option (a), you will have double-NAT, which can be problematic.
You would connect the new (filtering) router's WAN side to your existing router's LAN site. You cannot connect the two routers LAN-LAN as the new router will only filter/redirect traffic when it does the IP translation from LAN to WAN.
If your existing router has a Bridge option for its LAN connection, that would avoid double-NAT (bridge will connect the WAN side to LAN side transparently and disable all router NAT and filtering), but it's more likely that you would get a Static Route option before you get a bridge option.
Anyway, contemplate a bit, first check if there's Static Routes in your router's config. Sorry this has been such a verbose post.

I don't know much about modems/routers so would be a bit wary of setting up a new router. I checked in the setting on the modem/router provided by my ISP and there is an option to add static ip. Would that be a way to block Google's DNS?

Unfortunately not - and don't change that - you'll lose Internet connection.
While you're there, though, can tell me what options you have in the Working Mode dropdown where it currently says Router Mode?
DON'T change it though - that's likely to break your Internet connection too.

Cool. If you decide to get another router, you should be able to switch that dropdown to Bridge Only and connect your existing router's LAN port to the new router's WAN/Internet port, and it should avoid double-NAT-ing.
Essentially your existing router would only be used as a modem (and VoIP, if you're using VoIP), and you'd disable old router's WiFi and do all your DHCP, WiFi, etc on your new router.
As a rule I try (best I can) to avoid Dual Purpose networking devices as I have found they do neither task very good....
Unfortunately ISPs are moving towards these all in one boxes (Modem/Router/WiFi) and it Wreaks havoc on those who have their own networking gear....
Whats worse is they are locking the configs of these devices so that you can't change them easily to get it to do what you want.

You can also try this simple test without the router to see if it works....
Connect your computer directly to the Modem/Router...
Set the Router to Bridge Only mode and if your PC gets an outside (Public) IP Address then you know it will work with an external Router.
The only issue you might face is sometimes if the ISP provided the Modem they program it not to accept that change without it coming from their side.
I connected a new router (ASUS RT-N56U) to the existing router/modem. The existing was set to Bridge Mode with DHCP off and it can connect to the internet but not cast any show (local or US) to the TV. Not sure what details are needed for you to help me getting it to work. I can cast local Netflix onto my phone and tablet. YouTube videos can cast to TV.

Not totally up on the settings screens for your new router but check to see what IP Address it has under the Internet settings.
Every Router has two IP Addresses, one local (192.168.x.x) and one Public (should be provided by the Modem in bridge mode),
If both are local IPs then your double NATing which will easily break Netflix. If one is a Public IP then check other settings in the new router most notably UPnP and Multicast.
Also ( sorry dumb question follows) but you did make sure to set up the CCast to connect to the NEW router not the old one?

There are two IP addresses: 192.168.1.2, 192.168.1.254, first one local and the other public. I can't locate UPnP and Multicast in the router.
I made sure to set the Chromecast to the new network. The old one shows but it's not connected to the internet. It's in bridge mode.

As I suspected...Your Double NATing is the problem....Your new Router is not actually breaching the Modem to the Internet.
This modem also has WiFi built in I bet....
The DHCP you shut off probably doesn't apply to anything directly plugged into the Modem. Just the WiFi.
You need to look for a setting that gives you the option of passing a local/internal (192.168.x.x) IP or Outside IP and set it to pass an Outside IP. (this is on the Modem BTW)
If the Router reports any IP that starts off 192.168 for Public then you are not set up correctly.
If you see the option to change from local IP to Outside IP but it is greyed out then your ISP locked it out and they must make the changes on their end.
Call and tell them your Modem is in Bridge mode but doing double NAT translation and you can't breach the Modem with your router.

As @Asphyx said, there's double-NAT going on. This may be a problem, but the core problem at the moment is that new router's WAN and LAN are using the same subnet.
I recommend...
Turn off the WiFi on your old router, if you can.
Look for the stuff Asphyx mentioned.
If you get stuck, call your ISP
Ask them to enable Bridge mode and explain that you're looking for more robust routing and firewall features
Ask if there's a firmware update for your existing modem/router combo to provide this, if there is a different ISP-provided modem/router you can use that has better features, or if they can provide/recommend a modem-only device (if they don't/can't enable Bridge mode)
Ideally, you want to see is your new router getting a WAN address that is not 192.168.x.x
If you reach that point, you're done.
If not, you at least want your new router getting a WAN address that is in a different subnet from its local network.
On your new router, change the Local address to 192.168.2.2
That will switch things on the new router to the 192.168.2.x subnet. Now the new router and old router will be on different subnets.
Make sure any client devices (wired or wireless) that have static IPs set are changed to use IP 192.168.2.something and gateway 192.168.2.2
My network is double-NAT and I have not had issues with Chromecast, streaming, VPN, or anything else, but you definitely should avoid double-NAT whenever possible.
Please help me to set up chormecast in dlink 2750 u router
i can connect to router but it show not connect to internet
thanks in advance
What are the first 4 digits of your serial number? Just curious what firmware build you might be on. If you're on 12072 you might want to get root while you still can!
Looks like your router is D-Link 2750U?
Page 36 lists a Wireless Multicast Forwarding (WMF) option - you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 58 lists a LAN to LAN (Intra LAN) Multicast Enable option - again, you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 63 - Enable IGMP Snooping - you may need to toggle this setting.
Other than those, I dont' really see anything that would specifically block Internet access from Chromecast... Make sure you can ping 8.8.8.8 and 8.8.4.4 from the 2.4 GHz wireless network using another device if you can.
Sorry for the late reply
it work automatically
i just have o brought a wifi extender as my router far away from my tv
I had 2 Chromecast working just fine for a long time,one in the main network and the other in the second network in a room that is too far from the main router.
Then one day i disabled UPNP for security concerns and soon after I realized chromecast needed it and enabled it again, however i was never able to set up it again
I tried using many phones like Galaxy S4, RAZR D3, iPhone 6, Windows 7 PC, I tried resetting the Chromecast to factory defaults many times without success, then I tried the other Chromecast and reset it to factory defaults and could not set up it either, so the problem is on my network.
My wi-fi settings right now:
11n only, it's 2.4GHz only
Channel Width automatic,
Channel is set to 11,
IGMP proxy disabled,

My password length is 13 with ! and () and numbers
WPS disabled
Mac filtering disabled,
Transmit power high,WMM enabled,
Short GI enabled,
AP isolation disabled,
beacon interval is 50,
RTS threshold is 2304,
fragmentation threshold 2346,
using a DHCP server,
UPNP enabled(again),
SPI firewall is enabled ALG all enabled but SIP ALG,
Forbid ping packet from LAN,
Ignore ping from WAN(tried without this too, so i don't think it is this),
Parental control is disabled,
My router uses google dns by default.
I don't use any VPN
My router is a TP-LINK TL-WR941ND my firmware is up to date(3.15.9 for V5 hardware) it is connected to another modem that just run as a bridge and nat disabled if i remember right i don't think it is a problem it with it and the only options related to IGMP on it is IGMP proxy and chromecast support says it need IGMP enabled + IGMP proxy disabled so how i check out this?
I also tried moving the chromecast to a TV that is right next to my router, still get 'can't see the chromecast on your network',
I also tried to give the chromecast a permanent static ip, and port forward it(virtual servers on my router) 2-65535 UDP and 2-65535 TCP but still setup won't complete, i don't know what more i can do other than just trash this stupid chromecast and back to see all my series on laptop.
Sometimes i'm able to cast my tab from a little time after a failed setup but then soon it will say 'no chromecast found', my pc runs comodo firewall however it was not giving me any problem and i tried to setup it with it disabled.
For the god sake i just want to be able to watch my series again, anyone please help me! If you need any more info just ask it, i can run wireshark and send some prints if this can help too.
- edit
Tried today with an Ipad and has able to do the setup and got the screen ready to cast, however i see no ports open in UPNP, and the chromecast app on ipad said it was configured but was not possible to dectect it on my network, and also from time to time the screen would go back to 'connecting to your wi-fi' then go back to 'ready to cast' i was able to cast this table as i write this,will see if it will stay stable and come back.
On my Galaxy S4 GT-i9500 on my chromecast still says no chromecast found for some reason, but i'm able to cast from it, however i seems to get black tabs now when streaming to my chromecast which i don't like, verified the same for my Galaxy S5 , for my Ipad and for my Iphone 6, why????????? I can ping the chromecast too however i had 1% loss of packet on 200 pings in the same room as my router.

The main network is the network of the house and the second network is the network of the backyard, but i'm trying to run the chromecast in the main network, and the second is currently off.
The main network is the tp-link router as access point to a TG862 ARRIS in brigde mode, with firewall and nat disabled.
I think my wi-fi settings are all ok right? So why the chromecast can't setup???
I'd try changing wifi channel to 1 or 6. I'm not a network expert but I'd try that.
