I used to use my work wifi without any issues but since i upgraded the Android version to lollipop 5.0.2,since then it's not getting connected, though I'm able to connect to the phone data, but not able to connect to wifi, the status says connected but doesn't work at all. It's asking to login/register to wifi again and again. The wifi sign on top right also has a small exclamation sign on it. Don't know what to do to fix it, have already tried multiple times. Was happy to get the upgrade. If this doesn't work how can i go back to the previous android version kitkat ? Please help ? Last but not the least under wifi settings I see the Mac address but the ip address below has nothing, should there be anything ?
