Running Ubuntu 11.10

I got the driver downloaded, it shows under "additional drivers" in system settings.

Open it up and it says it's installed and operating, but I still can't get the WiFi to work.

What am I missing?

elaborate on wifi not working, are you not detecting any networks? networks detected and not connected? what are you using as your network manager?

Along with the above...

What make/model of card is it?
Is the module loaded into the kernel?
Is the kernel module installed?
Have you checked to see if the card needs a firmware package?

If for whatever reason you dont think the card is registering, check dmesg. Looking for 'net' in the output ususally gets you what you are looking for, but not always. Try doing a case insenstive search for the brand name of your card if you dont turn up anything. In my case, the cards I have are the one ones marked "Intel(R)" (the e100/1000e are the kernel modules bound to them to make them work).

$ dmesg | fgrep -i net

Do you have any hardware utilities insalled? I like 'lshw'. The console version (theres also a gui that i find less useful) gives you output like this:

$ lshw -C network

You should be able to install lshw from synaptic or just use apt-get/aptitude on the command line. The nice thing about lshw is that you can see the make/model of the card as well as the "driver=" bound to the hardware, along with all sorts of other useful stuff.

There is also the more traditional 'lspci', but you dont get quite as much info. Your card should show up here as well IF its on the PCI bus.

$ lspci | fgrep net

Can't manage the Wifi card at all.

The Network manager in Ubuntu doesn't give any option to use the WLAN. I downloaded Network Manager, but no luck with that either.

I downloaded Network Selector, but that doesn't seem to do anything. Maybe it has to run from the CLI?

I downloaded RutilT WLAN Manager , but that crashes with "Can't find any wireless network interface Code:-3"

Posted by neX_ Have you checked to see if the card needs a firmware package?

That was it.

Thanks guys.
