I just purchased a Galaxy Tab 2 7.0 and am unable to connect to my wireless router. I can see it on the Tab when I go into the wi-fi area, and I can see the Tab on the router when I look at it online. When I am in the router, it sees the Tab, but says that it's disconnected. I can connect at work and I can connect to an unsecured wireless network somewhere in my neighborhood, but I cannot connect to my own wireless. Any thoughts?
