Broke previously working WIFI with new wlan-ng drivers--how do I remove them?


I was trying to get Kismet working, and had a working wifi setup (that wouldn't work with Kismet). I installed the wlan-ng driver (wlan-ng-0.2.1-pre20) over the top of the previously working orinoco driver (from the 2.6.5 kernel).

I am using a 2.6.5 kernel on Slackware 9.1. My wifi card is a D-Link DWL-650 (old axe head prism2 chipset).

Now when I boot up, I get a message saying that the prism2 driver is loading, but can't get the card to associate with the orinoco module anymore.

How do I uninstall/remove/make modprobe forget about the wlan-ng prism2 driver?

I tried doing 'make uninstall' in the source directory, but had no luck.

I don't know where modprobe gets the information on what drivers should be assoc. with what hardware.

Thx in advance

rmmod prism2 or whatever its called removes it from the running list of modules...
Then, your going to have to go find the driver in the /usr/src/linux /wherever it installed to directory and delete it so it cannot be run again.

I had already tried rmmod, and modprobing the orinoco drivers, but the card wouldn't work.

Also I went to the modules folder in /lib and deleted prism2.o--and it still loads when I reboot the computer? I am at work, but will take another close look when I get home.

No luck yet

I basically did
Code:
rm -r /*prism*
I did the following to the kernel:
Code:
make clean
make mrproper
make
make modules_install
make install
I also downloaded the latest pcmcia-cs source, and did a fresh install.

When I start the computer w/ the dlink card in--it tells me that it can't find the prism2 drivers.

I don't know what I should do!

I still haven't been able to resolve this problem.

It's amazing that there isn't a standard (and widely adopted) way of removing apps and drivers that have been installed from source.

I can't figure out which files the drivers changed


Any suggestions are appreciated.

There should be an installion history file in the directory that you did the make Install for those drives. I can't remember the file name though. If you are REALLY into pain, you can read the Makefile and find out where everything was put.


As far as the drivers go, they are probably in /lib/modules/2.6.??/blahblahblah (look around in those sub directories).

To keep them from booting, Look for references to them in your:

/etc/rc.d/rc.modules
/etc/rc.d/rc.pcmcia
/etc/rc.d/rc.wireless (I think that's one)
/etc/wlan/wlan.conf
/etc/wlan/any other file in here


Turn off the modprobe of the drivers you want to kill.

I'm sure I'm missing info but, I don't have my laptop so I can't see the setup.

There is also /etc/init.d/wlan which starts wlan devices during boot (wland is run), which most likely causes the error where it can't find the prism2 driver.

Don't feel bad.

I do the same thing every so often when things get trashy.
