Are you using encryption ??? If so read on ....
I'm not familar with your distro or belkin, but I had a similar problem with PCLOS 2007 using Linksys Wireless_G Access Point.
I resolved it by changing the access point settings from WPA to WEP and also substituted hex for ascii in both the key & ssid fields.
Hopefully this may may help.

You may be able to find driver info
