cannot connect with wep

[archiepsi]

I'm running Xubuntu 8.04. I upgraded from 7.1
I have a dell latitude c610. 20 gig drive 512 meg memory
I have a wireless card with the Ralink rt2500 chipset.
My windows laptop connects fine but when i try to connect Xubuntu do not get an address.

ifconfig gives the following.

Have you got the linux-modules-backports package installed?

If you have, it could be this bug.
