Chrome-cast hookup with new password


Active Member
So I have been using an older chromecast. This morning Shaw came in and upgraded my internet. Unfortunately I did not do a factory reset on the chromecast beforehand.
Now the tv says can’t connect to wifi.
When I open google home it says disconnected device. “Check the disconnected device is online and ur phone or tablet is connected to the same wifi network. (So I need to get the chromecast onto the new wifi)
When I press settings it says “I am unable to access device settings”
I’ve unplugged the device and plugged back in with the same message.
Suggestions? I like streaming from my phone to the tv. Thanks
