I know this sounds a bit far-fetched, but I have had this bite me before. I
do not know your network topology, but check to make sure the distance
between your switch or router and your host is less than 500 feet in
length. I struggled with similar symptoms with a remote site I supported.
That was the fix.

Good luck,

Subject: [lug] Network connection dying mysteriously

My network connection is dying mysteriously. I did an image backup last
night ("telinit 1; cp /dev/sda /dev/sdb") and that is the only thing I can
think of that has changed.

After rebooting, I can ping my router but after 20 minutes or so I can no
longer ping my router. I reboot again and everything is fixed for another 20
minutes or so.

Does anyone have any suggestions on how I might diagnose this?

My network card is not a separate card, it is on the mother board. I run
marvel drivers for my NIC card.

I suppose I could get a separate NIC card and plug that in and see if it
fixes the problem. Uggg.. Any other ideas?
