Exclamation Wireless card not detected on Dell Latitude D420, Arch linux


I am running the latest version of arch linux on a Dell Latitude D420. So far everything has worked perfectly except the wireless. It seems that Arch does not even detect the wireless because ifconfig -a only gives me the loopback and eth0. I installed ndiswrapper as well as the drivers. lsmod | grep ndiswrapper shows that ndiswrapper is being loaded on boot. I tried to install the iwp3945 drivers, but they have become obsolete so pacman was unable to find them. I also tried installing the iwl3945 drivers as explained here https://wiki.archlinux.org/index.php...iwl5000-series but still no luck.
I am quite stumped and any help would be apreciated.
Thanks,
deadalus

ndiswrapper is for if you must use Windows drivers. Generally, if you can get a working native Linux driver that's better.

Are you sure the drivers you have installed are the correct ones? http://www.linlap.com/wiki/dell+latitude+d420 mentions some Latitude D420s use a different wireless chip. The lspci command should tell you what wireless chip you have.

If you have the right driver, maybe you need firmware, I'm not sure.

I may be missing something, but I don't see anything that has to do with wireless. Am I missing something?

The wireless card is turned on. WiFi Locator - Wireless On/Off switch to enable it. Sometimes the obvious is overlooked.

yes I checked that. I tried installing the drivers both with it on and off. But thanks for mentioning it because I have been known to forget to plug it in, attach a cord, flip a switch, etc.

May be your wireless-card is internally attached to USB. In this case, the output of lsusb would help.

Maybe the card needs to be reseated. Does it work in windows or different distro.

Here is the output of lspcmia:

Socket 0 Bridge: [yenta_cardbus] (bus ID: 0000:02:01.0)

I am wondering if I need some special firmware or something.

if your card works on windows you can try if it works with pinguy live. I has most drivers on it.

Another long shot. What is the output of lsmod. Maybe two conflicting modules or the wrong module is trying to take over the card.
