WEP KEY cause segmentation fault

[Civil]

Hi All,

I got the wireless networking to work on my laptop at the office where one of the neighbors in the building has a wireless network wide open ("silly wabbit"). The ESSID was still "default". Anyway, this was good for me so I could experiment with the WAN card.

Now I am home, where my network is protected by a WEP KEY. I configured the new network and put in the WEP Key. When I attempted to activate the WAN connection, I get the following error message:

"./ifup-wireless: line 65: 3582 segmentation fault iwconfig $DEVICE key $KEY"

Then the system hangs and I have to reboot. I even tried to edit the file
/etc/sysconfig/network-scripts/ifcfg-HomeWAN

and forced an entry for
ENC_KEY=0x012345ABCDE (example)

After a reboot, I tried to activate my HomeWAN network and I get the same error. Anyone know what this means and how to fix it so I can use WEP encryption?

Thanks for the help!

What wlan card are you using, and do you know if the driver for that card supports WEP? If the driver reportedly supports WEP, you may need to upgrade your wireless extensions.

I have an Acer laptop (TravelMate 2300), and I am using an acer IPN2220 Wireless LAN Card onboard to the MoBo. The driver is the same one used by someone else as posted on the ndiswrapper website. The driver is actually for the Acer TravelMate 4000, so I *assume* is supports WEP.

My WinXP partition likes the card and uses a driver by Inprocomm, which I know supports WEP. I guess my next step will be to try the driver WinXP likes...

Any other thoughts?

UPDATE:
I am using the same driver as the one used by WinXP. I just confirmed it. I updated to the latest kernel over the weekend, but didn't try WEP. I'll do that today and update this post. Anything else that you think I should try?

After booting the new kernel (2.6.10), I re-compiled ndiswrapper and re-installed the wireless drivers. I still had a solid internet connection, so I tried to use a WEP key. From the Shell, I used the command,

iwconfig wlan0 key 12345ABCDE

and I didn't get an error message. Hopefull, I removed the WEP key, logged into my router, set the WEP key there, then set the key on my computer in the Network Control Window. I restarted the computer for good measure.

After restart, it all worked perfectly! I attribute it to the new kernel, but I am now able to use WEP!!

The same thing happened to me when I set my WEP key. The cards lights would come on and I could see my home network with 'iwlist scan' but when I tried entering my WEP key I get a segmentation fault and the computer eventually locks up.

I tried the latest kernel and recompiled ndiswrapper. But after I 'modprobe ndiswrapper' the computer freezes instantly.

Not sure what I should do. I have a Microsoft MN-720 card and I know others have got this to work.

Anyone have any ideas?

Terata, there is a driver being hosted here

http://ankhcraft.com/drivers/mn720-ankh.zip

that might work for you. It sounds like there are some extra steps that might need to be taken for this card, but the driver above allows you to install without the extra steps.

I would recommend erasing your current driver (ndiswrapper -e xxx), then install the new driver. I think the fact that your computer froze means that the driver wasn't correct.

I've got that driver and the one off of driverguide.com as well

Finally got it setup last night. I went and downloaded a few older versions of ndiswrapper instead of the latest. The first one I tried, 0.12, seg faulted but 0.11 didn't.

Working great now.
