Duplicate acks and retransmission are the impact of the large number
of lost packets. Lost packets could be caused by a bad link. Try to
pingpath to the other end to see what's happening between you and your
parents-in-law (hope you don't have any problem with them at least :)

Hi --

I'm very new at this, so please forgive me if this seems naive r is in the
wrong place.

I'm having problems connecting from the UK to a PAP2 box at my parents-in-law
house in South America.

A wireshark trace shows what seems to my eyes to be a large number of lost
packets, duplicate ACKs, and retransmissions.

I've put the trace up at http://isw.me.uk/content/view/18/28/ along with some
capture of status reports from the modem.

I'm trying to identify if there's a problem at their end (line quality? bad
modem? bad configuration?), at my end, or somewhere in between (ISP

Is there anyone here who understands these things, or who can point me to a
better resource?
