I have a wireless network card and a wired network card on the
same machine. The wired card works fine, on interface eth0.

The problem is that the wireless card does not seem to have an
interface assigned. The card is an IntelPRO 3945ABG wireless.
I'm running SUSE 10.1

The approporiate kernel module seems to be loaded (ipw3945),
and Linux knows about the card (there is an entry for it in
/etc/syscondif/hardware) and yet I dont seem to have any
device or interface assigned to the wireless card.

There seems to be an appropriate setup script in
/etc/sysconfig/network

# ifup wlan-bus-pci-0000:0c:00.0
Interface is not available

but as you see, the problem is that the hardware is detected, but
has no interface.

Note that I'm not bothered about setting up the wireless network
or anything yet, I just want an entry for the wireless card....

Any ideas?

I've solved my own question. The problem was not having 2 cards
on the machine, I just needed to update some kernel
modules,

Instructions for getting the Intel3945ABG wireless working is at

support.intel.com/support/notebook/sb/CS-006408.htm

But, be warned, the ieee80211 firmware support that you install as
part of this process has changed between 1.1.13 and 1.1.14,
so I had to install the older 1.1.13, as the newer 1.1.14 version
breaks the compilation of the 1.0.0 (stable) kernel module for
the 3945 wireless card.

So, the procedure (covered in full in the INSTALL file
you can download from the intel utl provided above) is:

1) install ieee80211 1.1.13 (1.1.14 and later wont work unless
you use an unstable version of ipw3945)

2) install ipw3945 version 1.0.0 (my SUSE dist shipped with 0.7.something)

3) copy ipw3945.ucode to /lib/firmware

4) copy ipw3945d to /sbin


That is it (apart from the actual configuration of the card and network, but
thats OK, at least linux can see my hardware now, and I have a flashing wifi
light on my laptop).
