Suffered with this problem for over 4 years. Finally solved it. It's Samsungs crappy wireless network card - either the hardware or firmware- doesn't matter. Just go buy a wireless repeater for about $20, plug it in to an AC outlet behind the TV. Then directly connect your TV to that repeater with an RJ45 cable. It's been working flawlessly for 3 months now. Shame on Samsung for letting us suffer so long!
I've been doing that for my ancient network printer and scanner. However, aren't TP-Links suppose to be able to work in sets, or are the AC1200 before the mesh models? As I understand, any TP-Link model can join an existing network, even if the models are different. Why go with a simple repeater?
