I've got an Athlon box with a LinkSys lne100tx v2 card (see tulip-diag 
output below), going through a LinkSys 4-port NAT router.
I can make connections to the outside world, ping, UDP, TCP, etc.  but after 
a short amount of time, the packets get dropped at what seems from my 
investigation - at the router.  My investigation is: I make a TCP connection 
(say, ssh into an outside box).  I can use this for anywhere up to a minute 
or so with low packet transmission (keyboard input).  If I try to transmit 
files (ftp, etc...), it starts dropping much quickly - after a second or 
Other connections also seem to be affected when this is going on - i.e. the 
connection stalls - I switch to another vconsole and execute a ping to a 
well-known source (cisco.com) and it won't respond at all (no output from 
I kill ssh and ping, wait a few minutes, and things seem to recover, only to 
have the cycle repeat if another TCP connection is initiated.

I am suspecting it has something to do with burst sizes, but I am not a 
low-level networking guru, so I don't know too much on *that* low of a 
level, and could be way off base.

Anyone have any insight into this?
