[Cialug] Meaning of ethernet connectivity light

[Nathan C. Smith]

That's an interesting question.

I always thought it meant a link at the physical layer - which could still
probably happen in a "bad-card" situation, but certainly it varies based on
card implementations.  Some cards will present a link light before drivers
are loaded while others will not.

Subject: [Cialug] Meaning of ethernet connectivity light


I've been on the phone with Qwest tech support because I can't connect my
home computer to the internet; it seems that my computer cannot communicate
with the Actiontec modem.  The modem is connected via an ethernet cable, and
the little ethernet light shows green, but tech support is suggesting that
the ethernet card is bad.

Does anyone know how much needs to be working with the card/cable/modem in
order to get the ethernet connection light to go on, or how much can be
wrong before it goes off?  I'm curious about the general case as much as
anything specific to my setup.  How much functionality does that light
indicate?
