Comment 5 for bug 530275

I can confirm this is still an issue. I'm running this on a 1201N Asus eeePC. I have lbm-wireless 2.6.32-19 installed as well.

Here's the interesting part... it looks like everything is okay. It associates with the network and gets an IP address, however I am unable to ping any hosts on the network.
