Hello!
I want to buy a wi-fi adapter for my PC, which one will be the best in case if I need good ping for games, and speed is also important.
PC will be staying through the one wall between the router. Wall is like drywall but a bit rougher. 

I'm looking at TP-LINK Archer T2U Plus and TP-LINK Archer T2U Nano.
But both of them have not good reviews like they are "hot" and drop connection sometimes.

Would it be better to buy a USB or PCI-E adapter? Or maybe M2?

Hi, Archer TX3000E will be a good choice for you. It is powerful enough to play games.

Have a nice day.
