#Chromecast wont connect to wifi even with correct password update
I have had problems in the past when my primary DNS went down, all Google devices stopped working even though my Secondary DNS was working. 1: Check your Wi-Fi network Wondering why Chromecast can't connect to your Wi-Fi You may have recently changed your router password and forgot to update your Chromecast or added a second Wi-Fi network to your home and now your mobile devices and Chromecast are connected to different networks. I have figured out they will accept a third DNS server via DHCP but not a second. At the top left, tap Add Set up device New device. Follow the steps below to try to fix the issue: Open the Google Home app. I wonder if the new firmware just borked the wifi portion of the device?Įdit: I know all Google devices have hard coded their two DNS servers - 8.8.8.8 and 8.8.4.4. If youve lost your Wi-Fi connection or recently changed your Wi-Fi name, Wi-Fi password or service provider, you may need to set up your Chromecast device again. It still makes DNS request through my DNS server and Google is still blocked. After you manually connect to it and return to your Google Home mobile app, youll be asked to go through the setup process again. It should say the name that you gave your Chromecast device. Once I did that, the DNS storm by the Ultra ceased and I could cast again. If youre unable to complete the steps above, try looking for your Chromecast devices WiFi beacon on your WiFI list. However, for me - putting the Chromecast Ultra on a wired network solved my problem. I do DNS filtering to help protect the kiddos online, so I block all other DNS servers - including Google. Alternatively, switch to a different connection and try again. Then connect to a different network, such as a mobile hotspot. From the sign-in screen, go to the Status area, and turn off Wi-Fi. It's frustrating when a Wi-Fi connection doesn't work, and a lot of things can. If the problem persists, disconnect all the devices connected to your Wi-Fi network, except your Chromebook.

Try Updating Your Wi-Fi Adapter's Driver. Consider Distance and Interference Change Channel. I could see it would make DNS request through my DNS server and receive an answer, but it was making over 100,000 such request in a six hour period. Make Sure Wi-Fi Settings are Compatible With Your Device. 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). I could see it was connected to wifi with a strong signal. Once this was done, the chromecast connected to the WiFi without any issues and we were able to stream it without any issues. Those are the first 2 immediate questions that spring to mind - AFAIK the Chromecast will connect to the network even if it cannot connect to Google - the fact it is not connecting suggests either it is not getting an IP address or it is not authenticating with the network.

I had the same exact problem after the firmware update.
