Bought the Nexus 7 the other day and I?m having problems getting on the Web with it. Whenever I turn on the Nexus, I don?t get any kind of log on request, but rather a gray arrow that takes me to the home page and no Wifi. I sometimes get on the Web as ?guest? and I?ve successfully downloaded some apps with the thing plugged into the pc usb , but today when I downloaded an app that was ?installed? ? it was not installed with the Nexus 7 with its usb connection. To make a long story short, why can I only get on the Nexus as ?guest?? Where?d the Internet go? Does this sound like it?s a router problem (N600 DB Belkin)? This is exasperating to say the least and I?ve scoured the Web looking for some info on log on problems with Nexus, but I can?t find any. So here I am.
