Bug description:
With latest daily-live Maverick (2010-08-20), my wireless connection with
Intel 3945abg never go over 3mbps speed.
I try this in local lan and in internet.
It seems like a regression about iwl3945 driver, i had a similar problem with
older kernel where wireless speed was limited to 1mbps, with k/ubuntu 10.04 and
2.6.32 kernel this problem was disappear.
