My wife just got a refurb Streak 7 WiFi only. It worked fine for the first 8 hours or so and then it lost network connection on all the Amazon app store apps and facebook. The browser still worked.
I did a factory reset and everything was working again. Installed Amazon appstore and apps again and it lasted less than an hour before doing the same thing again.
Have any of you had a similar issue? I tried doing a search but couldn't find anything.
I am going to give it one more try and if I still have issues I think it is going back.
