could not find intel pro/wireless 3945abg network connection

verbose · 09-02-2006, 03:34 AM

I've had the ipw3945 driver working for a couple of months, but just a couple of days ago, it just stopped working, completely out of the blue. As far as I know, nothing changed in between.

The wireless card shows up in lspci, as well as under /sys/bus/pci/devices. The ipw3945 and ieee80211 modules also are displayed in lsmod.

When I both start the ipw3945 regulatory daemon and load the driver manually with the load script, I just get the same old error.

Thanks

Ideas, suggestions?

Anyone willing to lend a helping hand?

Thanks

What version of the driver are you using? Try re-installing the current version, or one of the newer development versions. Also, are the ieee80211 modules loading?

I'm using the latest version as of about a month ago. It just stopped working all of a sudden, so I'd imagine the version is suitable. The ieee80211 modules are loading, yes.

Give me a bit to work on this one.

Oh no no, don't work too hard on it.

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.

Also, there is a new driver on Intel's website. Just follow the link off of the development site (it seems to be out of date, by a few months).

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.

I've updated to the latest driver and I get the same error message.

It is possible that its your hardware.

When something stops working out of the blue, and theres been NO change in SYSTEMWIDE configuration and you have nothing else to blame.

Dual boot to windows just to be extra sure.

I was under the impression it was the hardware at first too, but I've already tried Windows and wireless works fine in there.

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.

No idea is a bad one.

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.
