We have a branch office connected over a high latency link (> 700ms), when connected directly into the modem a speedtest.net shows 8-9 Mbps downloads; when connecting the RAP-155 download speeds are reduced to less than 1Mbps speeds.
A wireshark trace shows a high rate of retransmissions and packet loss.
Is it possible to tune the RAP for a high latency link?
