[ubuntu netbook remix] UNE won't pick up my Belkin router

http://ubuntuforums.org – I'm a first time Linux user and have just dual-booted my Advent Milano netbook. I am running XP SP3 as well as Ubuntu Netbook Edition. After much troubleshooting and enquiring I managed to get the wireless up and running on it. However I can only connect to a nearby unsecured network. Ubuntu simply does not acknowledge my Belkin router. The wireless light is not even on. Yet it works perfectly in XP. My router is a Belkin Wireless G (F5D7634xx4A-H). Is there any way I can make it work in Ubuntu? I downloaded the .pdf of the manual but it doesn't mention anything about (HowTos)
