Question 3CXFE575BT/Inspiron3500/RH-6.2 problem 

Forum: 3Com PCMCIA Ethernet Adapter Issues
Date: 2000, Apr 15
From: Joe Christy <joe@eshu.net>

I'm having trouble getting networking going on a Dell Inspiron 3500. I believe that my 3CXFE57BT isn't auto-negotiating 100baseTx, which is what other machines on my network are talking, through a Netgear FE-108 switch. The symptom is that ping returns from my gateway escalate by 4 sec per return. Pinging from another machine to the laptop sees no lossage and 0.3 sec returns.

Diagnostics [from /var/log/messages, mii-diag, ping] follow.

Assuming that my guess is correct, can I force the card to 100baseTx?
