I just gave my wife my thunderbolt - and "upgraded" to a nexus yesterday (2-6-12)
I use data up quickly - with all music and movie streaming I do. So I try to use wireless AS MUCH AS POSSIBLE. Anywhere I'm at most of the time has a wireless network (home, work, gym, etc) so this isn't a problem. The only time I use Data is between those places.
HOWEVER, the ONLY spot out of those locations above that the GN will pick up wireless reliably is at home. It can physically "see" the network at my gym and work - but once it connects to them it cannot stay connected and it's a really weak signal. So I have to just turn it off and revert to 3G/4G performance. Contrary to what people have experienced with this phone, my 3G/4G isn't that bad (at least as good as my Tbolt), and it switches radios just fine.
However, this wireless issue is really a deal breaker for me because I can use up my 2g dataplan in 1 week if I'm always on 3g/4g.
Thinking of going and switching it to a Razr Maxx or Rezound and seeing how those are - but I REALLY like the phone's screen, OS, features, etc. Sh*tty wireless is just not an option for me though.
Anyone have any ideas/fixes? Do I have a bad phone or is this normal?
