Under Contents, click the Airport Card. If you have the plain Airport (802.11b) then make sure your Belkin router is set up to allow "b" or "b/g" speeds. If it is set for just "g" then your Mac won't be able to connect. If you have the Airport Extreme, then choose "g" unless your PCs cannot run at that speed. > Have never had wireless. Installed the Belken internet connection > to make the Mac the network hub. Go to the Network screen in System Preferences and click "Assist me" to run the wizard to set up a new wireless connection.
