Trouble with wireless setup

[mischa falkenburg]

Hi, I am writing this via my Xubuntu (9.04) installation, but I've also 
installed Studio (8.04) on this box so I'll have my choice in Grub.
OK, the install went alright...except it wouldn't detect any network 
stuff, etc.
So, it appears to be a functioning install, but I'm unable to get the 
wifi network connection going...even with it set to DHCP. Is it because 
of the difference in the versions? Does 8.04 have a "problem" because 
it's 8.04 instead of 9.04?
Any help greatly appreciated.
