In what way is it not working? Can you see the wireless networks at all?

make sure the card is enabled in the bios menu at boot. Also, when it's booting, press the key combo to turn on and off the wireless. do it several times throughout boot to see if you can get the led to come on.

I had the same card, and had to do that occasionally to get it to be recognized.

I have the same wireless card. It works fine over here in 8.04

Though I don't quite know how you're running 8.10 already ;)

I know that the only laptop I have had with a WiFi LED had a button built into the LED. When you pressed it, it activated the card or deactivated the card. Is it possible that the card has a button on the laptop like that and it has been accidentally pushed?

What model laptop do you have?

Also, do an lsmod in the command line and tell me if you see iwl3945 loaded.

i have the exact same laptop "lenovo n100" it worked fine with 7.10 but since upgrading to 8.04 this morning the wireless card stopped working and the indicator light is not coming on?? and no one seems to have any idea on how to fix this:confused:

i might just have to revert back to 7.10

I have the same laptop and i cant seem to get the 3945G to work, i tried everything i could find. The LED light wont turn on and it wont show or find any wireless networks. The conclusion i came to in the end is that the wireless card comes up as wmaster0, which has no driver and is not recognized by the system. While the wireless interface that the system is trying to use and loads the driver for is wlan0, which doesn't exist!? because i only have one wireless card. I think it needs some tinkering to get wmaster0 to load the correct driver and not wlan0, if someone knows how to do this please post it here i dont mind trying.

btw i get the same message from iwconfig as DO55 does.

HELP PLEASE

The LED issue seems fixed for my T60 with 3945 wifi using ubuntu backports using these instructions:

http://linuxtechie.wordpress.com/2008/04/24/making-intel-wireless-3945abg-work-better-on-ubuntu-hardy/

Although I still get flaky at best wifi. I've had partial success getting wifi to work by trying to force settings with iwconfig and following up with dhclient (I'm using wifi on Hardy right now, but it wasn't working for me for a few hours). Also I have better luck it seems when I have a network cable connected to the wired NIC, even if it is just connected to another machine, during the boot process, otherwise my wired NIC (eth0) doesn't get started properly - not sure yet why that matters, but I haven't gotten wifi to work yet without eth0 showing up. My wifi card is detected as eth1.

You can also use iwevent to kinda watch what is happening in a separate window.

Example:
sudo iwconfig eth1 essid LINKSYS ap 00:0B:86:97:34:A0 channel 1
(wait a moment)
sudo dhclient eth1

I'd really like someone to actually figure this out though, as this is an intermittent & admittedly completely half-*** fix. :)

Forgot to mention, use iwlist to try to force a scan for local wifi networks

sudo iwlist scan

Mine works fine, including the LED, with:
sudo apt-get install linux-backports-modules-hardy-generic

If that doesn't work you should know that the ipw3495 driver is replaced with the iwlwifi driver. Please follow the directions here at http://wireless.kernel.org/en/users/Download for installation.

My T60 actually worked - the LED is not lit but I don't have any problems connecting to wireless networks - but this should resolve your problems. Please let me know if you have difficulty following the directions...
