Question:

Solution:1

I had similar problems on my Thinkpad X1. Disabling wireless N solved that. What wireless driver/kernel module are you using?

#/etc/modprobe.d/_wlan.conf   options iwlagn 11n_disable=1  


Solution:2

In the future, I'd suggest buying hardware that's fully supported in linux to not deal with these issues: http://www.thinkpenguin.com/catalog/networking-modems

Second, you listed your PCI cards, while apparently you have a usb wifi card.

However, if you look here, someone seems to have gotten your card working in 11.10 http://myubuntunotes.wordpress.com/2011/03/03/hello-world/
