Last modified: 2007-11-30 17:12:11 EST
Description of problem:
Wireless ipw395 does not work with new kernels 2.6.22 in a dell latitude d520.
iwl3945/mac80211 does not detect wireless card when running kernels
18.104.22.168-27.fc7 and 22.214.171.124-33.fc7.
ipw3945 kernel module / driver, microcode firmware, regulatory daemon and
startup init script, following instructions at
works fine on kernel 126.96.36.199-27.fc7 but does not work on kernel
188.8.131.52-33.fc7 with same problem, cannot detect wireless card.
Version-Release number of selected component (if applicable):
ipw3945-1.2.1, ipw3945d-1.7.22, ipw3945-ucode-1.14.2
Steps to Reproduce:
1. boot the kernel
Wireless does not work
Wireless working fine
I think the iwl3945 driver did not get built in at least one of those kernel
versions. Please try the kernels here:
Do these work better for you?
I have that laptop, and with the newest two kernels (cant say with older ones as
its under one week old, but the install kernel didn't work), it works. Just make
shure it's on when you switch on the laptop (fn-f2)
Note that the led is'nt working, and if the killswitch is off during boot, i
have to reboot to get it on (and then tell neat not to activate the device on

No, did not work. Same problems with both iwl3945 and ipw3945.

Not sure what I am doing wrong but wireless does not work in my laptop. In
previous kernels I have never needed to check if the wireless card was on
(fn-f2) when I switch the laptop on.
Once the kernels at http://koji.fedoraproject.org/koji/buildinfo?buildID=12007
did not help, I have removed then and reinstalled the official update version
As mentioned by Kyrre, the led does not work with the iwl3945 driver. However
this driver was working in previous 2.6.21 kernels but was not stable. So I
decided to use the ipw3945 driver as advised by the site fedoramobile above, and
this driver was doing very well until this last kernel update.
After reinstalling the official update version 184.108.40.206-33.fc7, I tried once
again to use the driver ipw3945 and it is working now. I did the same steps I
used before without success with this same kernel and the koji's kernel. I have
no idea why it is working now.
Thank you all for the attention.
Given comment 7, I have no evidence that there is an actual bug here. I'm
closing this as NOTABUG -- feel free to reopen if this issue can be recreated.
