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.

:D 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.

deadalus.globalnode 01-26-2011 07:44 PM

I thought about that to, but hopefully I am just overlooking something. Here is lsusb:

Thanks for the replies so far.

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

deadalus.globalnode 01-26-2011 08:12 PM

Yes, it worked in windows. I just wiped the HDD and installed Arch linux.

cantab 01-26-2011 08:24 PM

lspcmcia ? bit of a long shot I'll admit

deadalus.globalnode 01-26-2011 08:39 PM

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. :(

yooy 01-27-2011 12:09 AM

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

colorpurple21859 01-27-2011 04:58 AM

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