I know my wifi works just fine in my house as my laptop and desktop are both connected to its just fine. Even my Nexus says it's got a fair signal strength but I know it's not transferring data because the icon in the top right is gray. For the first time I connected I had to turn my phone off then on to get it to connect but now I can't get it no matter what. I'm not rooted. Just got the phone last night. Does rooting fix this?
