Subject: Problem with in-kernel iwl3945 driver

Hi all,

I was using iwlwifi.git from intellinuxwireless.org with 2.6.23 kernel and it
worked like a charm. Now I updated to latest Linus' GIT tree and basically
wireless sufffers.

Here are some problems I encountered:

- Can't associate unless I do a iwlist wlan0 scan, until then it can't find
the AP.

- Even I associate Bitrate is 5,5 Mb/s but AP have up to 48 Mb/s and I am
basically 1 meter away from AP. iwconfig output is like this:

wlan0 IEEE 802.11b ESSID:"XXYYZZ"
Mode:Managed Frequency:2.412 GHz Access Point: AA:BB:CC:DD:EE:FF
Bit Rate=5.5 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Link Quality=95/100 Signal level=-34 dBm Noise level=-127 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

I guess in kernel iwlwifi and the one from intellinuxwireless.org is not in
sync, or there is another problem with in kernel driver? Any help is
appreciated.

P.S: Please CC me in your reply as I am not subscribed.

^^^^^^^
Looks like its in 802.11b mode instead of 802.11g. That might be a clu=
e for=20
slowdown.

This indeed fixes the slowdown, but can't associate unless I do a iwlis=
t scan=20
problem still persists :-/

I don't think that is related to mac80211 changes.

A fix was committed under the title "fix set_channel regression"
