Hiya,
Im using Red Hat Fedora Core 4, just switched over from Windows XP. Ive managed to install a lot of things so far, but ive come to a dead end with my wireless access card. Ive searched several forums for answers but i cant find one.

Ive installed ndiswrapper successfully, installed the drivers that my card needs and ndiswrapper returns "driver present, hardware present" when i issue /usr/sbin/ndiswrapper.
I issued /sbin/modprobe ndiswrapper and got no errors, /etc/modprobe.conf has been updated to reflect the wlan card.

Ive run through the network devices wizard, the card was picked up (ndiswrapper(wlan0)) and i entered the SSID, WPA key, IP, Gateway, Subnet mask and Channel without any problems.

I then ran Kwifimanager to see if it could pick up my wireless access point. When i pressed scan for networks it saw the network name, but wouldnt let me select it.

I then issued /sbin/ifup wlan0 and it returned this error:

Error : unrecognised wireless request "Mb/s"
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument

When i issue /sbin/iwconfig wlan0 i get this:

wlan0 IEEE 802.11g ESSIDff/any Nickname:"Adam_Laptop"
Mode:Managed Frequency:2.437 GHz Access Point: 00:00:00:00:00:00

Power Managementff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beaco

I looks like the wlan isnt reading the SSID i have set, the wireless.log file constantly shows trying to access network "any" (the same name as shown in Kwifimanager when looking for my access point).

I would really appreciate if somebody could point me in the right direction, i want the feeling of accomplishment when my wireless LAN is setup and working in linux, Thanks

Do you use 'iwconfig' to set essid?

It should be You also don't seem to have set a WEP key.

Thanks for your reply Xavier, I tried running that command as root but it the SSID isnt being remembered. I issued "/sbin/iwconfig wlan0 essid adam", didnt receive any errors, then issued "/sbin/iwconfig wlan0" and the SSID had reverted back to "off/any"... Have you got any ideas why? Also, could you tell me what parameter to use to set a WEP key? Thank you,

I know this post is a week old but I'm having the same problem now. Has anyone found the solution?

I have set the WEP key with:
iwconfig wlan0 key restricted xxxxxxxxxxxxxx

That went fine but I still get "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument"

Everything else seems to be working fine except for that error which is preventing me from accessing the internet. I installed ndiswrapper, loaded the driver, so driver and hardware is present. My network is visible when scanned for but I'm going crazy because I can't connect to it!

Anyone?!

According to the Installation Wiki, you sometimes have to run "iwconfig wlan0 commit" a few times to get it to take. Whenever I have encountered the error message when setting the essid, I usually rerun that line until the error stops appearing. Then I continue with the rest of the commands.
