I just installed Redhat Fedora Core 3 on my Gateway 450 laptop, then attempted futiley to get the Cisco 340 (AIR-PCM342US) card configured. These are the messages I get when I attempt to activate the profile through the network configuration:

Error for wireless request "Set Mode" (8B06) :
SET failed on device eth1 ; Invalid argument.
Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth1 ; Invalid argument.

Determining IP information for eth1... failed.

I do see "Aironet PC4800" listed under the Hardware tab. Also, I was unable to find any 340 Linux drivers on Cisco.com, but could find drivers for the 350 card.

Any suggestions on what to try?

Thanks!

I'm having the same issue. I haven't noticed the error messaeges, just lots of RX errors.

In this case, I'm not using WEP, but mac address filtering.

If anyone has their's working, posting the configuration and steps would be good.

I'll do some more work on this...

Posting from linux now...

Turns out it was IPV6 support causing issues.

Though my initial run I simply moved the ipv6 directory out of the modules directory, this may prove to be a more graceful solution.

echo "alias net-pf-10 off" >> /etc/modprobe.conf
echo "alias ipv6 off" >> /etc/modprobe.conf

I do see references in the network sctrip in rc.d/init.d to $NETWORKING_IPV6, but I'm uncertain as to where this variable is being set.

So then, I manually set my key (Though oddly I'm not using a key on the windows side... just mac filtering)

If this doesn't work for you, there are some other things I've done I'll have to double check on.

Since I'm using a PCI-PCMCIA adapter, you may always want to make sure the proper module for your pcmcia sockets is being loaded. if in doubt, modprobe yenta_socket and see if it takes. airo_cs should be the corresponding module for your card.
