I am using an n800 with os 2008. I have a Dlink wireless router, which works fine with two different laptops. The router is set up with WPA security with pre-shared key. Yet when I try to use the NIT, "select connection" can find the signal, good signal strength, but when I enter the pre-shared key, all it does is ask for the key again, and again, and again, never getting in. This same key works fine with the laptops we have. Any ideas?
