View Full Version : [ubuntu] Where can i find and download wireless driver (.INF) file?

July 8th, 2009, 09:33 PM

sorry for the constant problems however i spent about 4 hours so far researching and trying to get my wireless working and getting VERY frustrated.

I downloaded the ndisgtk from Synaptic Package or Manager however i do not have the windows.INF file for my driver.

been following this guide


so where can i find the .inf driver and download it?

From the manufacturer of your hardware. This might have been given on a CD or be available from the recovery partition of your hardware. What device is it?

BTW I wrote that guide, has it helped?

July 8th, 2009, 09:39 PM
yes it was quite helpful

the troubleshooting guide was step by step and was easy to follow (even for a computer noob like me :P)

however when i installed Ubuntu i believe i deleted everything off my harddrive (including backup) and do not have the CDs from the original package either.

I'm glad it helped, the troubleshooting guide wasn't a popular addition.

You should be able to get the drivers from either the hardware manufacturer or the computer manufacturer - which device is it, if you open a terminal and type:
sudo lshw -C networkPost the output here and we can see the device and revision.

also i found a few .INF files from the Intel Site and installed it using the Windows Wireless Drivers however it reads "Invalid Driver!"

when i run


it reads

lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

You need the entire driver, not just the .inf file - are you expanding the entire archives?

Can you post the output of:

You shouldn't need a windows driver because the device is associated. When you attempt to connect from network manager, does it show any available connections?

July 8th, 2009, 10:04 PM
running 9.04 (jaunty) and didn't see a network manager

however i saw a network tools (System -> Administrator -> Network Tools)

and i dont see any networks i can connect to

July 8th, 2009, 10:08 PM
also nothing in System -> Preferences -> Network Connections that i can connect to

July 8th, 2009, 10:21 PM
Network manager should have an icon in the notification area that looks like two overlapping computers.

i had wireless working for a minutes by doing
alt+fn then using
nm-applet --sm-disable

however after i rebooted it was no longer working then
the "enable wireless" button beneath the "enable networking" no longer shows either

i uninstalled some stuff thinking i didn't need them anymore
could this be the problem?

July 9th, 2009, 12:21 AM
The driver is associated and iwconfig looks correct. It depends on what you uninstalled and I'm not sure what the options do as I didn't think nm-applet too options. In fact, this chipset should work off of the Live CD.

Do you mean you have to connect manually every time or that you're asked for a password to unlock the keyring?
