When I first set up my Smart TV it connected to wifi straight away. The next time I turned it on it still recognised the wifi but couldn't connect to internet. I tried it with a wired connection which worked first time but again, the next time I turned on the TV it can't connect to the internet. I am with BT using their Smarthub. I've tried changing DNS to 18.104.22.168 and 22.214.171.124 but no change. Please help.
I have got something weird to add into mix. My tv was bought in Jan this year everthing fine. Then around June it stopped finding the wifi. Power off at the wall and you powered back up it would find it. Soft reset it would find it. Full reset it would find it. But always after 15 - 20 mins wifi would drop. Called Samsung and eventually called out an engineer whi ordered a network card, a main board! and the plastic back shells in case they broke. Still waiting for the call back on that one...
But in the meantime I have changed my broadband provider from BT to Sky and i thought "What the hell!" So i did a reset and changed the wifi. Not only did it work, but IT HAS STAYED CONNECTED!!! EH? Checked every day for over a week. No issues. And it says it's the same firmware. Any guesses coz I am confused.
Same problem for me Model UE65MU6470 - Works most mornings then losses internet connection although all other devices seem ok. Software is stated as being up to date. Have tried various DNS changes and turning off the TV at the power source as well. Any ideas on how to take this one forward?
