Re: Nexus 7 Wifi bars are white
I think the OP is on KitKat but used to JB so not realizing that it is always white on KK and that you have to go to the notifications pull down to see the orange color or the little arrows to know if you are actually connected to the Internet.
As for accessing the Internet, turn airplane mode on then off and you'll be okay. For permanent fix, you have to set your Wifi SSID mode from like DCHP to static WHILE IT IS CONNECTED TO THE INTERNET.
