Comment 0 for bug 276684

Description: Ubuntu intrepid (development branch)
Release: 8.10
Kernel: 2.6.27-4

After installing the new kernel and getting rid of the old one I cannot see any wireless connections. I am using an intel pro wireless card ipw3945. I guess there is a problem with the driver...

Here is the code:

# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

eth1 IEEE 802.11abg ESSID:""
          Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
          Tx-Power=0 dBm
          Retry min limit:7 RTS thr:off Fragment thr=2352 B
          Encryption key:off
          Power Management:off
          Link Quality:0 Signal level:0 Noise level:0
          Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0

# iwlist eth1 scanning
eth1 Interface doesn't support scanning : Network is down

# ifconfig eth1 up
SIOCSIFFLAGS: No such file or directory

do I did # dmesg
....

and finally # ls -1 /lib/firmware/$(uname -r)/iwl*
ls: cannot access /lib/firmware/2.6.27-4-generic/iwl*: No such file or directory

It seems I am missing the driver or what... But it should be in the kernel already, should it not? Since I installed 7.10 it was working fine with the intel driver and than 8.04 was using already the linux driver iwl3945 and besides the led everything was fine...
