TV keeps disconnecting from WiFi

[Ryanww28]

Hi, my Samsung smart TV (UE49NU8000 49, purchased 11 months ago brand new) keeps disconnecting from my WiFi. I have spoke to Samsung and they have even gone to the measure of sending a third party company out to replace the part that connects to wireless networks. However, its still doing it. 

The only way I can get it to reconnect is by turning the TV off and on again, it will not reconnect if I try and do it through the network settings, I have to turn the TV off and on again. 

I have spoken to my Internet provider, and all is fine on their side, and no other wirless connection (phones, Xbox etc) ever disconnect. 

I have done multiple factory resets, most of which were done whilst on the phone with Samsung, and all updates are done too. 

I am at a total loss, can anyone help? 

Thanks.

I hope this helps anyone with this problem. I had been dealing with it for quite some time on my newer 65”, and like many others was at a loss.  Tonight, on a whim, I tried changing my IP from obtain automatically to manually.  I simply took the IP, DNS, GATEWAY, etc that was given to me in automatic mode, and switched my network settings to manual IP and entered those numbers.  For the first time in close to a year, I was able to watch an entire movie without interruption. After all I tried, this worked. Wow
