Cable modem - OK on USB, not on Ethernet
 

I have a Elite K7SEM (v. 1) m.b. with an onboard Realtek RTL8139/810x
ethernet interface. I have a Toshiba 2200 cable modem. I'm on Time
Warner Cable in Queens, NYC.

When I connect my cable modem to the ethernet port, I get that a cable
is disconnected, even though all the lights including the computer
light on the cable modem are lit correctly.

When I connect my cable modem to the USB port with the Toshiba drivers
for Windows I'm connected OK.

I'm told that Ethernet is slightly better - faster, USB may not be
compatible with a broadband phone system and/or Linux. Any ideas? If
the cable really is disconnected, why is the computer light on when
the Ethernet cable is connected?

I've rebooted (including shutting off the power to everything) n times
where n is a much too large integer.

Usually swap cables, check the pin / color connections / if the LEDS are
on then it's not likely to be a mix between a patch or crossover cable.

Sometimes maybe it's as simple as changing the PC NIC.

That will be WinXP / 2000 then?

It may not be a hardware issue (in my case at least) a fully working
system, overwrittem by XP keep showing this message.

At work 2 very similar Dell laptops both Win 2000 / same docking
stations one shows a cable disconnected every so often, the other never
did.

Ethernet is generally a lost faster.

Don't know, but it's easier to share Ethernet and it's less of a
processing hit on the CPU.

If you mean the link light, it's a very basic test and can function even
if the data LED doesn't. Normally both would be out at the same time.

Have you tried to connect the ethernet to something else to verify the
NIC works?
