If you can ping without packet loss the problem is almost certainly with
routing, not with the driver.  You likely have a NAT router that doesn't
forward ICMP echo packets.

Routing problem..

What was the driver detection message?
What are the statistics from /proc/net/dev?

Normal..

Bogus values.
What does the detection message report?  What does 'eepro100-diag -m' report?

There is nothing to set.  The transceiver wasn't detected.  Since the
transceiver is on the same chip, it's difficult to guess what is going wrong.

Anything unusual about the BIOS? Perhaps the chip is in D1 or D2 PCI power
state?
