[ubuntu-in] My Laptop Wireless is not getting detected

[consoleart]

Hi all,

I installed Ubuntu - Hardy Heron on my Compaq (Celeron) 
Laptop,(alongside Windows XP). My office uses wireless to connect to the 
network and internet.

But in Ubuntu I am not able connect to the network, then i checked my 
network connection, it displays Wirenetwork and ppo, but my wireless 
network is not getting listed at all. Please help me.

Thanks
Jag
