Hi, I purchased a 2013 lte nexus 7 about 3 weeks ago. When I first got it everything was fine. Then It started having wifi problems. It would connect but I wouldnt get any throughput. I have two different routers and had the same issue with both. I have a 2012 nexus 7 and a phone and they both connect fine with no issues. I have reset the phone four time. Each time things will be fine for a day or two but I get the same problem eventually. I exchanged it yesterday at best buy. While I was there the girl at the counter connected to a router in the store. She said she didnt do anything special. But I went ahead and got a new one. It wont even go through set up. It sees both my routers and connects but when it tries to go to the next screen it says web page not available. I have an tmobile sim card and I really dont want to return it but I dont know what else to do. I have searched and cant find the answer. Before I returned the first one I tried everything suggested and nothing worked. Thanks for your time.
