I have a TV Q70T 4K (2020) working for 2 years, but a couple of weeks ago the wifi stopped working and it does not recognize any wireless network. I already reset it to factory several times but the problem is not fixed, I also reset the router and nothing. I can only connect to the internet wired. The TV is updated to the latest version available (2200). Can anybody help me?
Sometimes it is necessary to change the DNS Settings,Go to Network-Network Settings-DNS Settings. Change from Automatic to to 22.214.171.124 or 126.96.36.199 (Google servers) An alternative is Open DNS 188.8.131.52 or 184.108.40.206
In some cases it can be the wifi module though.
