I have a Samsung Galaxy 10.1 tablet. It been great for the past year, but all of a sudden I can't get any internet access on it from home. I reset the network and have it connected, it just doesn't do anything. I took it to work and it connects and gets access just fine. I upgraded my router's firmware and still no luck. Even tried a hard reset of the tablet...nothing. Any ideas why I can't get my tablet to access the internet, even though it's connected to my wireless network?
