I just bought a nook tablet and am not able to connect to my wifi. I know wifi is working because my other nook can connect. I type in the password (which is the correct one) and it says "obtaining IP address" but nothing happens. I click "help" and it says "error 106." It suggest I change my WEP security to WPA or WPA2 setting. HUH?

Could someone please help?! Danka!
