So the 3 ways to get an Intel IPW3945 working, are:
1. The IPW3945 drivers at sourceforge.  This requires ipw3945d binary 
daemon running.

2. The Intel Restricted drivers available in Ubuntu in the restricted 
drivers section.

Both of these should should IPW3945 as a module when you do a sudo 
lsmod.   lsmod will show you what modules are loaded as opposed to 
lspci, which will show you hardware the system detected.

3. Use the foss iwl drivers, which I believe show iwl in the lsmod output.


Do you know what driver you were using?  Again I think this is a 
kernel/module problem.
