Chromecast Unable to Connect to Network

Hey all. New poster long time lurker. I just wanna thank everyone in advance for all the help I've gotten over the years.
Anyway. I own a chromecast and am attempting to connect it to my home wifi network. I'm using a mi424wr-gen3i router with the latest firmware. I disabled IGMP and UPNP is enabled. I turned on IPv6 like some other posters mentioned. My phone (Bionic) gets to the set up page, sees the chromecast but fails at one of two points. Either it says it cannot communicate with the device or it gets to the point of connecting the chromecast to the network and fails. My network is using a WPA2 security key. As far as I can tell my router is not a dual band and only transmits at 2.4ghz. The chrome support mentions something about Access Point/ Client Isolation, but I have no idea what that is or how to configure it. I called both Verizon and Google. Google said check upnp and 2.4 ghz. Verizon said its not their problem.
I was following this thread which seemed to be point on, on my issue. However where other people seemed to make it work, mine still fails.

Have you tried rebooting your router, disable MAC address filtering if it is enabled, and/or reset the router's settings back to default

Yeah. I rebooted to the factory reset. Unfortunately its a verizon issued modem/router combo and its to their specs. MAC filtering is disabled and its been rebooted.

Get the latest router from Verizon & turn off IGMP. Swapping out the router should be free.

I was having a similar problem but I realized that Chromecast only needs the network name and it's password to work. After the step were you put in the password and it fails, I should work..Also, if you are getting stuck renaming chromecast, leave it the way it is for now. Before you start over, check to see if you can see chromecast on you network using Fing or a similar program.

I have had same issue and fixed it by doing a MANUAL entry of all wireless connection to your router... type in SSID, pick WPA2, and enter passcode.

Well after several hours of talking with Google and Verizon again. Verizon hung up on me and Google solved the problem. Apparantly my phone (Droid Bionic) is not communicating with the device properly. Off all things i was able to set it up with my buddies IPAD. Ironic right? Now I just need to figure out what the heck is wrong with my phone. I read somewhere that the razrs were having problems. The Bionic and Razr are one in the same so i guess ill head that way. Anyway thanks guys.

It's always a good idea to try different devices when possible. Adding the Google Cast extension on Chrome for the PC may be the easiest to work with since you're using a full keyboard.

I had to manuilly allow my chromecasts Mac address... Then it worked no problem.

My wife's razr had the same issue. You could have also used your PC to set it up.
Here is the thread on the Razr / Bionic issue: groups.google.com/d/msgid/chromebook-central/1280fb6a-d063-4d77-993d-dbec4fc6cdb6%40googlegroups.com (sorry, you have to copy/paste it, I have less than 10 posts so I can't post links yet).
Play Music and Play Movies/TV probably won't work for you either.

Just hit Try Again and it will work. It fails the first time, and hitting Try Again did the trick.
Not sure if it was luck or what not.

Chromecast will not connect to my TELUS ROUTER

Chromecast wont connect to my telus router (Actiontec V1000H). I can't see any option to enable/disable AP Isolation. Is there any solution for this?

Good advice.
Remember that the WiFi bands (channels) are not exactly the same between countries. So if you're in a non-US country and your router happens to choose a channel that is not available in the US, Chromecast may not detect your wireless AP.

But Telus is Canadian, and Canada has the same WiFi channels as the U.S. (Canada and the U.S. necessarily share identical radio spectrum allocation).

Didn't know that. Thanks! Still applies to other countries though. I think Channel 13 is one of the channels that applies to Europe but not US. I should put it in the FAQ...
EDIT: Seems there's far less exclusion than I thought... but added a note in the FAQ just in case.

So I can get through the setup phase up until the Chromecast tries to connect to my wifi network. I get a message saying it couldn't connect, and when I click the link in the message it brings me to a page that mentions AP filtering, UPNP enabling and .NET 3.5. I checked and UPNP is enabled, and I can't find an option for AP filtering (I have the Actiontech V1000h). I am using a Macbook pro.

In some cases you have to go through a couple of times. I just reset my Chromecast to test a few things and had to go through the setup twice before it connected to my WiFi.

Chromecast in Canada, on Telus
A friend lent me his chromecast. He uses an iphone and Shaw cable. I use a Nexus 4, and have Telus as my internet provider.
It was a bear trying to get chromecast to work. Tried 5 separate days. Got it to work and i could watch netflix/youtube on it about 3 times and played with it for a couple of hours each. That's the success.
The fail is that I had to trouble shoot more then 4+ hours to get it to work those 3 times. Reboot the chromecast. Reboot the router. Reboot my Nexus 4. Try my wife's Nexus 4. Try the Nexus 7 tablet. It was a horrible experience. I got the AP recommendation like the earlier post in this thread. I tried that. Tried calling telus and signed into my router to check that those settings were correct. As far as I understand it's a gateway 11n wireless router.
So my conclusion is change my internet provider to Shaw unless someone has a smart solution to this problem. The router says it's a 50ghz signal? So it isn't the 2.4vs 5.0 ghz signal problem that I've googled and read about.
Please provide some brains to my situation. I've used all of mine up.

Still not fixed.
So I took the plunge and bought one. Maybe it'd be different than my friends. Looks like this is a me problem. The chromecast still doesn't work. I thought it might be the tv that it's plugged into? Maybe shielding the chromecast from the wifi? I don't know. Will trouble shoot with a different tv or a long hdmi cable that will get the chromecast out from behind the tv. Maybe that'll help.

TVs are great at blocking/scrambling radio signals.
Use the included HDMI extender. If that doesn't help (enough), get an HDMI extension and move Chromecast away from the TV. One of mine is on a 10-foot HDMI extension. The other is connected upstream of a another device that connects to my TV, so both of my Chromecasts are at least a foot away from its associated TV.

It could be a few things not related to the router directly but related in how the Router connects to your ISP.
So a couple of questions...
What kind of service is your ISP? (DSL, CABLE, OTHER)
What Public IP does your router report? (Usually found on the status page that shows connection data) If it starts off 192.168 then your Modem is doing a double nat translation and you need to call your ISP and tell them you want the Modem to be put into gateway mode and just pass a public IP to your router.
Does the CCast actually connect to the Router but not work or will it not connect at all period? If it doesn't connect at all it is possible you need to change the Security method used to WPA or WEP. To test shut off security alltogether and try to connect the CCast. If there is currently NO security try putting WPA on and trying again (but it should work on an open AP)

Service is Telus DSL.
Solution: I changed the security settings. It still tries to stop the CCast from talking to my phone once in a while, but I just log into my router and log into the firewall settings. The firewall settings are "high, medium, low, NAT". It started working once I started turning it off of NAT and onto Medium or High.
I don't know why this is the solution, but it is a solution. I suspect that either Telus will fix the prolbem for everyone else or this thread will become popular. Now CCast is coming to Canada. So either Telus fixes it or there'll be a lot of searching leading to this post.
As a reminder, a friend of mine on telus never toughed his firewall settings and never had a problem with using his CCast. Go figure.

Well if the Telus was set to NAT perhaps Double Nat Translation was the issue.
DO you have another router connected to your modem or is this one of those all in one Hybrids supplied by the ISP?

I have a friend that is struggling with this as well. While setting up the WiFi connection between the chromecast and the router (the Actiontec V1000H - which is a modem/router combo if that helps). The chromecast will see the WiFi, but it seems to time out while trying to connect to the router.
I did find a comment on a blog somewhere (sorry, I forget where) that suggests unchecking the "IGMP snooping enabled" option in the router (Advanced Settings>IGMP Setting). Once this was done, the chromecast connected to the WiFi without any issues and we were able to stream it without any issues.
However after going out for dinner we had major issues trying to connect to the WiFi on our phones and his laptop (laptop would try to connect to the WiFi but continually fail). It seems like this is a temporary fix at best.
The only permanent solution I can think of at the moment is to go buy a new router that is listed as having no issues on the chromecast compatibility list... Which kind of defeats the whole purpose of having the chromecast as an economic way to stream content to your big screen.

Buy a better router

I don't see why IGMP should have any affect on being able to login and connect.
I Can see it being a problem with streaming but not connection.
IS this an ISP provided Modem/Router? How many devices are connecting wirelessly?
Check settings for IGMP Proxy, Try changing that setting whatever it is but it should probably be disabled (Still don't think this would affect connection but it's worth checking)
Check if UPnP Is enabled (again not really connection related but it does need to be enabled for CCast)
I personally prefer to use a two device setup with separate Modem (in Bridge Mode) and Router....This way the Modem protects the router from the outside world and even if the Modem goes bad the Network still functions properly.
And I pretty much stay away from anything that isn't a Linksys or Netgear product as far as Routers are concerned.
There are a bunch of Actiontec models that are listed as incompatible with CCast on the google site so it's obvious that something about their firmware is not CCast friendly.
So the the previous poster may actually have made a good suggestion in the long run! LOL

I'm using the telus actiontech router with chromcast with no issues....
its a pretty crappy router though and it seems telus disabled the ability for bridge mode in the latest firmware... has anyone found a solution to this so i can buy a better router?

As long as double NAT doesn't cause you problems, you can
Assign the new router's WAN port to an address in the ISP router's LAN range
Set the new router's gateway to the ISP router's LAN address
Connect the two routers LAN port to LAN port
Have all your wired and wireless clients connect to the new router.

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.

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.

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..

Issues with new TWC modem/router

Hi all, while thinking that faster internet would be a good thing, it seems that I have managed to break chromecast compatibility with my network. Previously I had a Netgear router that worked perfectly, but when we got an upgrade to TWC's new "Extreme Internet" they installed a new WiFi router/modem hybrid that I cannot seem to connect to. I get the message that it is connected to the network but not the internet. Ap isolation. Is disabled, but I cannot find the plug and play feature anywhere in the network settings. Has anyone found a work around?

If you can give us the exact make and model we might be able to help more.
BTW, TWC changed their policy a few years back and now allow approved customer-owned modems which will save you the modem rental. They used to not charge for the modem rental but also not let you use your own. Installed a Motorola SB6141 for my relative and it's been working great with the Netgear WNDR3700 I put there.
No Chromecast yet because I haven't been by to visit...

You could always use your own modem with twc, just that most people did not know that. Like previously mentioned, more details are needed in order to further assist you. Make and model(tg862g, ddw3611, dvw32011b???). More than likely you just need to call and talk with level 3 tech support. I personally used my own router behind the modem because I do a bit more than normal with my router.

I went through Hell on Christmas Eve with Time Warner....
They have a new Modem/Router they are using....When connected to a personal Router it does a double Nat translation which really doesn't work at all.
Your lucky if you even get Internet access on a Computer with it.
Check your router and see what IP address it has under internet connection. It should not be 192.168.0.x
If it is not an outside IP you need to call support and tell them you need your Router to breach the Modem and have them shut off all ROUTER capability on their Device so that all it does is pass a public IP to whatever is connected to it.
If you get your phone service from Time Warner as well better call on a Cell Phone because they will drop the phone call the second they mess with their Modem/Router and you will suffer through Groundhog day explaining it to the next guy from scratch!

Well guys I solved my own problem in a way. I disabled the wireless broadcast from the TWC Arris router and just connected my old NetGear ( old as in 2 months old) and it seems to work perfectly now. And the installer said, " You won't need to use your old one because this box is like commercial grade bro."

Glad to hear. The wireless modem you have is indeed a great modem and you could use that alone but it is easier to just use your own. The installer more than likely wasn't on the up and up about the more technical aspects of the modem. You can't knock him for that part as the techs are not trained on a lot of the extra features of the modem. I only know this because I may or may not work for the company(need to keep work out of forums).

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
id = [a very long number]
fn = Bedroom
ca = 5

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.
