This posting is a rewrite of a preveous posting, but with more
readable information allong with some new information.

I am trying to get a 3Com Etherlink III (3C509B) ethernet card
running on RedHat 9.0 but cannot seem to get it working.

Setup:
WAN
|
3Com <--> Router <--> Other PC

If I set the card up to DHCP it's addres from the router the bring up fails,
so I switched to a static IP, then it "comes up fine" (no error), however I
cannot ping into or out of the card.
I can ping my system from itself (ie local host, or via it's static IP)

There are lights on on the ethernet card and the link/activity light on the
router is flashing

The cable/card is fine (as it will DHCP fine if I boot the network install
disk
(It get's an IP addres..), it just doesn't work correctly if I boot off the
normal boot floppy (my GRUB is also messed up...))

I have read that there may be some problems with this card, but I'm not sure
where to look to determine what/how to fix (I'm new to this portion of
linux). (how do I figure out what driver I have etc?)

I have no clue why 169 is there... I did remove it after a previous install
with no differences
