I have a Thinkpad W520 and Ubuntu 11.04. The WiFi card is spotty. It works 80 percent of the time, but every few minutes it hangs and gets "stuck" for a few seconds before working again.
So before I resort to replacing the WiFi card, how can I see if there is a WiFi driver update and how can I install it?
lscpi -v shows that my WiFi is:
