Bad ethernet onboard card/1 good PCI card/Cable Modem/

Post by MaskedTechSupport » Fri, 03 Aug 2001 00:14:59



I have a bad ethernet card on my motherboard of my compaq.  When I put
a new card in a PCI slot, it took me ages to get it to work with my
cable modem.  Any time I made any change that involved networking I
had to uninstall dial up networking, delete my winsock2 registry keys,
and reinstall dial up networking.  Well, I had a copy of windowsME and
I wanted to improve the look of the machine (upgrade IE and Outlook
Express, etc.), so I foolishly installed it.  It took me ages to find
how to uninstall dial up networking, since it wasn't an option on the
windows disk. But, although some software is no longer complaining
about not getting a socket, I can't access the internet.  I can PING
and my FreeNetMon sees packets coming in, but I can't get IE or email
to work this time.  This is adelphia.net soon to be replaced by
comcast (thank god!?)

Any thoughts?

 
 
 

1. Good card?...Bad card?

Can an ethernet card be defective in such a way that it performs
some tasks apparently well, but not others?

A new SMC EtherPower card can connect to atHome's dhcp server and
negotiate the cable internet connection ok: it gets the ip address,
name resolvers, etc. But performance sucks, as evidenced by these
pings:

If an old NE2000 clone is substituted for the SMC I get decent
performance. But is this evidence for a problem with the tulip
driver (runs the SMC card), which _no one_ on the OpenBSD list
reports, or with the SMC card?

This card "passes" all the tests supplied by the floppy distributed
by SMC with the card. I *think* the card's nfg, but how am I going
to convince SMC of that?
