From the factory for most Linksys:
1. Surf to 192.168.1.1.
2. admin is user, password is "admin".
From the factory for most D-Link:
1. Surf to 192.168.0.1
2. admin is user, password is blank.
Once into the management screens browse around until you find where you can set the WEP or WPA key. Once set you'll have to provide the key when you computer connects to your router.
