Smart tv not connecting to wifi

[Frankie26]

This started a few weeks ago, being tempermental when turned out and starting up. 

I’ve had to turn it off and leave it for 30 secs then turn it back on but that’s stopped working now. 

What could be the issue and any advice on a fix? 

I only bought it in December 2018 so it’s incredibly annoying. 

Its a Samsung UE50NU7020

I think a new firmware for the majority of models seems to be causing chaos see my thread here - https://eu.community.samsung.com/t5/TV/QE49Q7FAM-latest-firmware-has-made-wifi-unstable/m-p/1178203

Yes. You can rename your 2.4ghz name or 5ghz in your home router. Your Samsung has problem reading or switching between them both. Or you disable 2.4ghz and problem is solved to.
