Bug Description

Binary package hint: linux-firmware

My Intel 6200N, using the iwlagn module, can no longer connect to an 802.11n 5Ghz AP. Logs below:

I cant seem to find a list of reason codes anywhere. If I boot of a Lucid live CD, I can connect fine.

This probably isn't a firmware issue. All of my Intel 620x adapters work in 2.6Ghz. 802.11n is definitely problematic, but we're not going to get a Maverick fix from Intel.
