Problem with in-kernel iwl3945 driver

Problem with in-kernel iwl3945 driver

[Ismail Dönmez]

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.

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

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

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.
