I've been trying to set up my xbox 360 with a wireless adapter, and thought that the reason it wasn't working may be something to do with my router I went into the settings page of my router - something like http://162.198.1.1 and stupidly changed it from WEP to WPA, and now my wireless connection isn't working and I can't get back to that page to change it back!!! Any ideas as to what to do?
