Already tried to version 2009 and other

Don't have LAN cable in that room. Isn't that strange that all of them broke down just after warranty?
Anybody else?

Already tried. No result :/
Changed also firmware backword to 2009. No efect :/
Anybody knows how to check WiFi is hardware failure or is it some kind of software fu*kup by updates?

TV is searching for WiFi and after almost minute closes rotating circle without any info :/
Then you can only repeat or cancel network settings :/
Problem was on firmware 2017 so i updated to 2018 but problem not resolved :/
