Cant find my wep key

goto start- run- type cmd & press enter.in the dos window type ipconfig press enter. whatever the default gateway is copy it. open internet explorer type that default gateway in address bar press enter.it will ask for user name and password.most of the time user name and password is located on the back of the router on the sticker.when you are in goto wireless settings.if you can read the security key then you can use it if not then you have to change the wireless key and connect all wireless computers again. hope that helps.
