I've bought this tv (Philips 43PUS7303/12) 3 weeks ago and everything worked perfectly until today.
After I came home from work I tried watching some Netflix and it showed I was disconnected from the internet. I connected it again but the same thing happened.
I even completely reinstalled the television but the same thing occurs. There were no software updates between the time it worked and when it stopped working.
Did someone experience a similar issue? I'm quite worried that something is broken and I need to return it.
Edit: thanks everyone for your replies but nothing seemed to work. Oddly, changing the wifi password has fixed the whole issue.
I had a similar issue with the 50PUS7303 bought last week, but I think it was just a matter of poor WiFi signal. My TV is two floors above my router so I couldn't catch the 5 Ghz, and 2.4 Ghz kept disconnecting indeed. I plugged a CPL closer and it seems to be working now...
