Hi, just bought 65A7400F....

Suppose it can receive both 2.4G/5G Wifi right?

Currently manage to connect with 2.4....while it cant detect 5ghz (as compare with my phone connected only with 5ghz wifi)

Yeah, in normal condition that wouldnt be big issue unless i try online stream higher resolution movie...sometime it may lag

So, would it be problem with my wifi or my tv?

How to setup?
