it should autonegotiate to whatever speed your network card is, it's a 10/100 card so you shouldn't have to do a thing.

Incidentally, i think you can do

SPEED=10MB

for wireless cards, not sure if it would work for wired.

the other solution is


options eth0 options=0 full_duplex=0

in /etc/modules.conf

(you can set it to 1/2 duplex by setting full_duplex=0)

Thanks.  I didn't really understand how you came up with those numbers so I searched google and found this site

http://support.3com.com/infodeli/tools/nic/linux/readme.txt

it pretty much sums up everything you can do with the 3c90x.o module.

yes sir, and if you read that document:

OPTION: full_duplex
    Allows overriding of the default duplex setting for the hardware.  
    Note: Invalid combinations of media_select and full_duplex are ignored
    by the driver.

    -  Hardware default     [ Default ]
    0  Disabled
    1  Enabled
     
you will find that section, as an option to add to the driver either on the command line with insmod, or in /etc/modules.conf as I said.

I got it to work finally, not exactly sure what was wrong. I ended up removing the network card with suseconfig then reinstalling it and it worked fine.

I needed to find out how to change those settings anyways, so i will give you the answer

my guess is that when you removed it the autoconfig set it up for you, sometimes that will work.

The 3x90x is a popular module, most all of the distro's should be pretty good with it.
