Google Chromecast 3 Connectivity Issue: Can't Connect TV, Setup Error & Network Troubleshooting

Hello, I can not connect tv with chromecast 3, I do everything as in the manual and finally the message pops up - chromecast has been configured but you can not find it, make sure that tel and chromecast are connected to the same network. I tried on another tv and other phone but the same. I went to the router's address and the device is visible as connected, even though after disconnecting it from the network and reconnecting, only the WiFi network name is visible for a while. Chromecast displays some pictures on tv and does not react to anything

I understand that models of devices are covered by the secret?

Tv Samsung ue46f5000aw, tel. Huawei mate 10lite, router tenda n300

The problem is with the router, I set the hotspot on one phone. I connected a second phone and chromecast with it and it worked. Problem with my WiFi network, I talked to the internet provider and claims that the devices are from one pool and must be seen and I do not see wireless isolation on the router or something like that

Hey,
Did you manage to solve the problem?
I have a similar problem. Everything was working for me for a long time and now I have the same as you.

I have a similar problem. I wanted to connect the chromcast to the home network. Chromecast initially gives a link message. Later, however, a message pops up that something went wrong. I have a TP LinkTD W8961ND router. Somewhere, I read that you need to turn off the AP isolation, however when I did it, the whole Wifi internet network disappeared was only on the direct connection with the cable to the router. Does anyone know what I can do with this problem. greetings

It works !
I read the net and did it according to the instructions from this site.

Namely:
1. I turned off, unpinned the chromcast
2. I turned off all mobile devices in the home that I used to use for chromcast
3. Turned off the router
4. I left everything turned off for over a minute
5. I turned on the router
6. After turning on the router and waiting for a few minutes, I turned on the chromcast
7. I turned on mobile devices.

I have re-configured the chromcast from scratch and surprisingly at the beginning nothing has changed. Again a message appeared at the very end
"chromecast has been configured but can not be found, make sure that tel and chromecast are connected to the same network." After a few minutes of thinking about what else to try, I noticed that the chromcast connected to the network and everything works. Check it out and this will work for you

The phone is connected to WiFI and at the same time disconnected from the Internet from the mobile network operator?

For me, the same problem. The problem started as I wanted to configure the device for a new router. Failed to. Return to the old to no avail.

Hello, with me, as I said, there was a problem with the router, I typed the router software version in Google and on the English-language forum was given a link to upgrade the router software, I found even newer and updated, the configuration of the router after the upgrade has not changed. The Chromecast immediately worked and flashes. In the old version of the software, there was no option to isolate the access point, after the upgrade, yes.

Half problem solved. Router Tenda F3 turns out that it has problems with Chromecast and there is some unofficial firmware that solves it.
I made a reset of the devices as above and I managed to configure it using an old tablet with the TP-LINK 1043ND hitherto operating. From our discussion and other forums, it appears that the reason is mainly routers.

Hello
I'll get under the topic if I can. Namely, I have a problem connecting to the chromcast from a laptop. The tablet goes without any problems but unfortunately the laptop in chrome does not find chromecast. Can you get it somehow?

I have such a problem, there is a picture on the old tv, not on the new tv, I also connected via a new receiver and it is not there. There is a video signal at startup, while after a while it turns off as if it was changing to a different frequency or resolution. Is it hdcp 2.2 or another HDMI cable? Chromecast 2

Hello
I solved my problem - it turned out that the culprit was Nod32

Hello forum users, I'm hooking on the subject. I have chromecast audio and in my case chromecast is not visible at all, in Google Home it adds a new device and nothing like it was not there. Everything is connected and connected, the router is dir300 from Netia. I am begging you, honorable, because I will crumble this box a little bit, I will add that this is the first start-up of the device, I followed your instructions from the post and nothing.

I had a similar problem at a friend's house and the instructions worked for me; the router was not the same though, sorry!

Hi, has the same problem. Ie. configuration message at the end. Chromecast 3, the router is Raisecom ht803g-w-03. I don't see the router's configuration options to enable access point isolation. I've already tried re-enabling, resetting, new configuration, but the same every time. Anyone have any idea and could help?

Search the router for Advanced WLAN settings and change the channel from automatic to 2 or 3 and wi-fi bandwidth to 20MHz.

Thanks for the reply, unfortunately I do not see such settings at home. In general, I have some options inactive.

I would like to ask for some cheap router model that will work with chromecast. Well, I don't really get there. It has to have an optical input (for optical fiber) and at least one LAN. Can be used.

This is how it looks with me and no matter which Wi-Fi option I choose, I can't choose the channel and frequency anyway. However, I can't find the software for this router anywhere.


I guess it remains to replace the router? I checked the image sharing on the chromecast on the other phone and then it works, so obviously there is a problem with the router.

I have the same problem but it only happened after changing the router from tp-link to arris tg2492, unable to connect to the new wifi network, anyone knows some effective way?

I probably managed to solve this problem, disconnect the chromcast with hdmi from the tv (do not disconnect from the power source) there is a small button on the chromcast, press it and hold it for about 20 sec, then connect again to hdmi and connect again from the google home application .

I have a similar problem. I have an Asus GL504VD laptop and Canal plus box connected via hdmi to a Samsung TV.
Everything worked fine until the update and now I can only upload the image using Chrome. Previously, I could do it through windows without any problems. I can't find this device at all. But he already finds two other miracasts without any problem. Could something change after the update and is it going to unscrew it?
