ubuntu upgrade broke my wireless


Recommended Posts

Hello,

I have googled constantly on how to fix this issue. I cannot find the driver in a .deb package or some other way that I don't have to compile and do things that I really don't know what to do. I am running ubuntu 8.04, what's the best way to get my wireless back?

thanks

How did you get wireless working before? Did you use madwifi?

I'm guessing it worked out of the box on initial install, he did some updates, and now it's FUBAR'd...which seems to be quite common with Ubuntu.

Welcome to the world of linux. Read the link in my sig. ;)

Probably missing the restricted modules package which include the madwifi driver.

apt-get install linux-restricted-modules-`uname -r`

If you're looking to download a deb manually just search http://packages.ubuntu.com/ for linux-restricted-modules and the kernel version you're running.

i.e linux-restricted-modules-2.6.24-19-generic

It worked out of the box, I upgraded from 7.10 to 8.04 and now my wireless doesn't work.

let me give you some info about my system configuration:

uname -a

Linux brian-laptop 2.6.22-14-generic #1 SMP Tue Feb 12 02:46:46 UTC 2008 x86_64 GNU/Linux

Why I have a SMP kernel is beyond me. I did my original install with a generic amd64 ubuntu iso.

When Ubuntu is booting up, I can see how it detects the right wireless card, but I need the driver.

Through google, i THINK i need the iwl3945 driver.

The problem is that I don't find it in a .deb format, or through synaptic or apt. I only find tar files that I dont know how to use, and I dont think I have the compilers installed on my computer.

----

Rob2687, I have the restricted modules installed. "linux-restricted-modules-2.6.22-14-generic is already the newest version."

Through google, I found out that this suggestion actually fixes the wifi light not turning on, on people that already have their wireless working.

And yes 39 Thieves, this is annoying sometimes. The upgrade also broke my video drivers, but those I managed to fix. :)

Thanks for the help

try this?

http://moustafaemara.wordpress.com/2008/06...untu-804-hardy/

or:

if people are still having trouble with the intel 3945abg wireless networking and iwl3945 driver:
create /etc/modprobe.d/iwl3945
add the following lines:
alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1

save and close, run update-modules or sudo modprobe -r iwl3945 and add it back or just reboot

but i dont know which one I need, or how to install them.

I wish I could do this through synaptic or apt :(.

there's a link there with detailed instructions (for building a driver from source you'll need build-essential, that you can get from synaptic)

Have you tried using your Windows XP 32Bit Driver with NDISWrapper?

ndiswrapper -i <driver.inf>

ndiswrapper -l to see device status

ndiswrapper -m to add the code to modprobe.d

modprobe ndiswrapper
