Hi. I'm having the same problem, again. The first time I solved it changing from 5ghz wifi to 2,4. I really didn't understood it but...it seemed it was solved. Same problem now, few days later, I've tried everythings of this site and nothing is working. The problem is happening with the wifi adapter, I'm almost sure. I presume it is auto shutting down when the TV doesn't use it for a while...today I fell asleep with it going ON,I shuted it down while working time and 6 hours later I've arrived home and it is not working... ... I'm just finishing writing this ticket and I just solved it again: - TV without electricity about 5minutes. - Turn it on. - Come back from 2,4ghz wifi to 5ghz. - Works. - Looking for updates: nothing. - Smart Hub autodiag: nothing wrong. ... It clearly smells like a poor wlan adapter set. ... Model UE55MU6105. V. Soft: T-KTMDEUC-1210,8 BT-S ... Excuse my poor english.
