Installed nvidia driver and now and wireless is gone!

[shadroth]

Hi all,

I've been using kubuntu and wireless happily for some months now. Today I installed a new video driver, nvidia, so that my laptop could communicate with an external monitor. Bumpy road but eventually got it working. Later that day I when I got home I was horrified to find that I could not connect to my wireless network and when I checked under Network Interfaces in System Settings I saw that my wireless card was no longer listed. I have no idea what nvdia could have done to my wireless driver but I presume something has been messed up somewhere. Can anyone please help!

Here are some basic commands for more info:

[shadroth@box ~]$ iwconfig

eth0 no wireless extensions.

cipsec0 no wireless extensions.

I have seen other forums on this topic, such as http://kubuntuforums.net/forums/inde...ost;board=29.0
but none of them have solved the problem for me.

Thanks in advance.

Re: Installed nvidia driver and now and wireless is gone!

I've been doing more investigation into this. The driver seems to still be there:
/lib/firmware/2.6.22-14-generic/iwlwifi-3945-1.ucode
/lib/firmware/2.6.22-14-generic/iwlwifi-3945.ucode
But I don't see a /etc/hotplug/firmware.agent file which, according to my limited understanding, specifies where the firmware directory is.

Please help!

Hmmm -- that is a strange result.

Is networking (via ethernet) working? If not, maybe a

sudo /etc/init.d/networking restart

would get both ethernet and wireless going again.

Otherwise, if you're happy with the video performance, I'd say pretend you never had wireless before, and follow the procedure to install the firmware, install the driver, and configure the interfaces for wireless.
