My Wifi on my new Thinkpad W520 running Natty keeps dropping out and coming back on. Output from dmesg below. Any advice?

I had this problem with Maverick so I installed the package linux-backports-modules-wireless-maverick-generic and I got a very stable system. (This packaged provided more recent wireless kernel modules than the default kernel.)



For Natty there is no package linux-backports-modules-wireless-natty-generic. - But you can try to install linux-backports-modules-cw-2.6.39-natty-generic and maybe your disconnects will go away. :)
