Public bug reported:

Hello,

in the new lucid kernel my wlan connection has become very unstable.

I use the NETGEAR RangeMax Wireless-N-Router WNR834B-v2.

I have to run sudo modprobe -r iwlagn and sudo modprobe iwlagn over and
over only to get some packages through the wlan.

I switched back to the previous kernel which does not have this issue.
