I have just installed Fedora for the first time, and am running into
problems with my NIC. The box has a 3com 905B card in it, which is capable

the link partner also has this capability. However, the link auto
negotiates to 10full. I have tried forcing it via mii-tool, but it won't
take the change. I added these lines to modules.conf:

"options 3c59x options=4 full_duplex=1"

But, that failed to obtain a link at all. Below is the output of mii-tool
with no driver options:

eth0: 10 Mbit, full duplex, link ok
  product info: vendor 01:e1:c1, model 56 rev 7
  basic mode:   isolate, collision test, 10 Mbit, full duplex
  basic status: autonegotiation restarted, link ok
  capabilities:
  advertising:  100baseT4 100baseTx-FD 100baseTx-HD flow-control
  link partner: 100baseT4 100baseTx-FD 100baseTx-HD flow-control

Any ideas how I can force this to 100full?

Thanks.

I use the 3c59x module too and I couldn't make my card work properly with the default autonegotiation, so I forced 100-FD both at the switch and my computer, and now the errors are gone.

These are the relevant lines in "/etc/modules.conf":

######
# Tarjeta de red (3Com 3c905C-TX/TX-M [Tornado])
#
# 0x200 = 10BASET, FD
# 0x204 = 100BASETX, FD
# 0x008 = Auto
#
alias eth0 3c59x
options 3c59x "options=0x204"

Hope this helps.

I have a similar problem with same card, but my hub uses 10baseT 1/2 duplex, and no matter what I
seem to do with mii-tool, the card stubbornly stays at full-duplex, 10baseT and the outcome is horribly slow data rates
with ton's of frame errors..best it'll do is slower than dialup, lol! Card works well in XP, and correctly is set to 10baseT HD
