You can directly connect your computer to the router thorugh the routers "internet" port and then re-run setup. OR you can type the IP address of the router into your address bar (the default is tipically 192.168.1.1 or 192.168.0.1) and then enter the router username and password (I believe the Belkin default is username:"Admin" password:"Password") in the admin control planel look for a "wireless security" tab. You can then define your wirelss security settings there. Just remember to configre the same settings on all devices that will connect to the router.

Go to the router's web interface (192.168.1.1), in the wireless section go to Wireless Security. Enable WEP, you will create a WEP key for your wireless network, then that key will be asked to any wireless device that tries to use your wireless network.
