Tracking down eth0 issues

[Richard Crawford]

I'm having a devil of a time staying connected here at work today.  I suspect 
some sort of network issue in our office (I've got the only Linux box; 
everything else here runs 'Doze).

What happens is this:  every few minutes, my network connection just vanishes 
for no apparent reason, then comes back up immediately.  This is particularly 
annoying when listening to streaming music or chatting with someone via IM or 
when trying to check my e-mail.

I've tried leaving a terminal window open with "ping <gateway" continually 
running, but that shows nothing.  I've looked at my system logs, but they say 
nothing related to eth0 or networking issues.  I've also tried a live capture 
via ethereal while the network drops and reconnects, but found nothing that I 
can interpret as an error.  This is a brand new laptop with a brand new 
network card, so I'm hoping desperately that it isn't that.

Where can I look to find out more about network interface troubles my computer 
might be having?
