I think the iwl3945 driver did not get built in at least one of those kernel 
versions.  Please try the kernels here:

   http://koji.fedoraproject.org/koji/buildinfo?buildID=12007

Do these work better for you?

Comment 2 Kyrre Ness Sjøbæk 2007-07-27 15:15:53 UTC
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)

Comment 3 Kyrre Ness Sjøbæk 2007-07-27 15:16:53 UTC
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
boot...)

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.

Comment 6 Sergio Morais Lietti 2007-07-27 22:36:24 UTC
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
2.6.22.1-33.fc7.
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. 

Comment 7 Sergio Morais Lietti 2007-07-27 22:59:54 UTC
After reinstalling the official update version 2.6.22.1-33.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.
Sergio

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.
