Ok so what your saying is that when you go on to networksettings on the dashboard it wont give you any wirless scan option?
(New dashboard)
*When first starting up your xbox on the dshboard go up one to "My Xbox"
*Once on "My Xbox" go alll the way to the right and go on "System Settings"
*Once in "system settings" go on "Network settings"
*Once on "network settings go on "Configure Network"
(And this is where people often forget to press A once again)
*So you should now have alll the technicle stuff; IP Settings,IP Adress....Press A once on this screen and it should give you 2 choies, one of them being "Scan for wirless" or something like that.
Hope this works
