Galaxy wifi fix
My phone was able to connect to the wifi but I couldn't access the internet using wifi. I have the Push to Talk app on my phone. I contacted my provider and they didn't help. I called Samsung and they wanted me to send the phone in for repairs. I then contacted a different person at my provider and they helped. Go to settings, wireless and network, mobile networks, access point names, then click on browser, go to 'proxy' and make sure it is blank. * before you blank it, write down the info that is in there incase this doesn't work for you * turn your phone off then back on and presto it works!
