 Posted: Sun Aug 29, 2004 1:36 am Post subject: How I got WEP to work with the Linksys WPC54g |
 |
|
Using the excellent HOWTO posts for ndiswrapper and wireless-config, I was able to get the Linksys WPC54G PCMCIA wi-fi card working in my Gentoo laptop. However, I could not get the card to work when I enabled WEP on the access point. It turns out that I was using the wrong syntax for iwconfig. I hope that this info will save someone severe frustration.
My AP uses 128 bit encryption, which generates a key with 26 hex digits. Looking through Google and the ndiswrapper mailing list archives showed that lots of people had this problem, with several cards besides the WPC54G. I was getting the following error message:
| Code: |
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument
|
Further, the following appeared in dsmeg as well:
| Code: |
wlan0: setting wep key failed (C0010015)
|
It appears that each type of wi-fi card has its own peculiar syntax for setting the WEP key, here is what worked for my WPC54G:
| Code: |
# iwconfig wlan0 key XXXXXXXXXXXXXXXXXXXXXXXXXX
|
where XXXXXXXXXXXXXXXXXXXXXXXXXX is the key used by your AP.
It is likely that this info is obvious to everyone (except me!), but I hope this post helps someone with this card.  At the very least, this should help those who use "WPC54G" as a forum search.

Which version of the WPC54G do you have? Mine is v.4, and using the latest drivers from Linksys and the an emerge'd ndiswrapper-1.1-r1, I can't get WEP 128 to work.
What I do is the following:
| Code: |
modprobe ndiswrapper
iwconfig wlan0 essid "<my ssid>" key <KEY>
|
However, dmesg spits out:
| Code: |
ndiswrapper: using irq 5
ndiswrapper (NdisWriteErrorLogEntry:273): log: C000138B, count: 1 (00000102), return address: e1c939be, entry: e1ca7000 offset: 4294887870
wlan0: ndiswrapper ethernet device 00:0f:66:2e:00:98 using driver wlipnds, configuration file 17FE:2220.5.conf
wlan0: encryption modes supported: WEP, WPA with TKIP, WPA with AES/CCMP
ndiswrapper (set_essid:58): setting essid failed (00010003)
|
And iwconfig reports:
| Code: |
eth0 no wireless extensions.
lo no wireless extensions.
