Are there any error messages in dmesg when the driver loads, and is the firmware still in the right place? BTW, I don't mind helping, as this is one of the few ways that I can give back to the community.
Are you referring to this driver on Intel's site...link
As you say, it's a couple of months old. I downloaded the ipw3945 driver from sourceforge only about a month ago and I believe it's 1.1.0. I don't have quick access to the laptop right now so I'm not entirely sure, but I remember 1.1.something. I don't really think the driver version is the problem, seeing as wireless was just working and then, one day, it just stopped.
edit: Maybe you're right and I should update the driver. I checked and my driver version is 1.0.2 (Apr 2006). The latest was released in August. I'm having difficulties getting eth0 to work on the laptop, but I'll get it working sometime.
This may sound stupid, but is the firmware in the right place? If you have done any updates to the o.s., the location that the firmware needs to go could have been changed. Try unloading the driver, and then loading it back up. Then check dmesg to see if the driver reports any errors.
I checked which directory the firmware should be placed in by going to /lib/udev and looking for FIRMWARE_DIRS in hotplug.functions. The ipw3945-ucode README says that if multiple directories are shown, the firmware only need be in /lib/firmware, which is where it is. I could also try putting it in /usr/lib/hotplug/firmware but I really doubt it will do anything for me.
Nope. I tried putting it in this other dir and wireless is still unusable.
