The problem is that g3212 is unable to detect 5ghz wifi network, while d3202 connect to that network successfully. Is 5ghz supported by G3212?
which build number does your phone has?
settings > about phone
also, take a look at this
It's 42.0.A.1.90
Hmm, I have dropped and recreated 5ghz network, and now phone detects it just fine... So, the problem is resolved, thanks.
