Hi
I'm not quite sure if you are connecting to machines across the ADSL 
connection, but if you are that would be the first thing to check as 
the line could be dropping and reconnecting a few seconds later.

Otherwise it could be a problem with lost packets. Some ADSL routers, 
especially the black SpeedStream ones that BT supply on business lines, 
have a habit of dropping packets under load or overheating.

Running flood ping or pinging over a long time to different hosts may 
help track down the problem. If the packets aren't arriving then 
ethereal probably won't see a problem.
