iwl3945 is unable to connect to wireless network
Last modified: 2008-07-10 15:02:15 EDT
Description of problem:
iwl3945 is unable to connect to wireless network. ndiswrapper works fine with
same NetworkManager setup. iwl3945 in FC7 works fine on the same hardware.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Load F9 on Dell D620 equipped with IPW3945 wireless card
2. Try to connect to WPA Personal/TKIP/PSK AP
Unable to connect to AP
Must connect to AP
All networks are visible, but unable to authenticate on AP. I tried to play with
options hwcrypto and disable_hw_scan options - no success. But ndiswrapper works
fine with the same NetworkManager setup.

Successful connection using ndiswrapper card
I can confirm this problem. It works with kernel 18.104.22.168-55.fc9.i686 for me,
but not with 22.214.171.124-76.fc9.i686
I don't have 126.96.36.199-55.fc9.i686, only initial 2.6.25-14.fc9 because system was
just installed. Tried to boot 2.6.25-14.fc9 - works fine.
I can confirm this issue on the kernel 188.8.131.52-76.fc9.x86_64. Working fine
again when booting kernel 184.108.40.206-55.fc9.x86_64.
Dell D620 with iwl3954 upgraded to 220.127.116.11-76.fc9.i686 yesterday and wireless
stopped working using NM (and WPA), error appears to be at the point of the
"wlan0: link timed out." error message as shown in comment #1.
AP appears to be fine as the macs and wii continue to work.
Note that Dell has an a10 firmware out for the d620:
This appears to have wireless compat fixes which may help, sadly, the
firmware-tools as shipped in F9 is too old to install this firmware using the
Dell tools, which are requiring firmware-tools >= 2.0.0. Bug to bump
firmware-tools is #454204
Tried the BIOS update from above (a09 -> a10) which does not appear to resolve
the problem. Bummer.
I can confirm this is a regression from kernel-PAE-18.104.22.168-55.fc9.i686 (works)
to kernel-PAE-22.214.171.124-76.fc9.i686 (breaks).

More one with same problem. Same thing of comment 3.
This bug does not seem to be just iwl3945 related! I could also reproduce it on
a machine with a Linksys WMP54G (RaLink RT2561/RT61) using the rt61pci driver.
Again, no connection possible with 126.96.36.199-76.fc9.x86_64, but working with
Confirmed on iwl3945 as well, same "link timed out" problem.
.55 works, .76 does not work.
Is there any ETA on a fix?
