Quick suggestion GetBack - do not use wep, use wpa-psk (it lets you choose a password/key yourself). For your key, use numbers in some places to enhance the security of it ie b1ngb0ng etc - and enable mac filtering on your wireless endpoint (you'll have to input the mac addresses of any laptops/desktops wireless cards - which can be found by typing run, cmd, ipconfig /all, look for the wireless card, use that mac address and you should be golden)
HTH,
