Wireshark · Wireshark-users: Re: [Wireshark-users] Large numbers of lost packets, duplicate ACKs, and retransmissions?

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 :)
).
