I recently changed my router password from WEP to WPA because I was assuming someone in my apartment building was stealing my wifi. Ever since I have been unable to connect to XBL. I manually put in the name and password, but it shows NO bars on the available networks screen. What do I do? I tried restarting the router, unplugging the adapter, etc. I do use an original XBox wireless adapter from last gen if that makes a difference.
