Very High Latency and Jitter
I'm trying to access a remote work site via RDP. The remote end is a small rural provider; the local end here at home is Xfinity with the Blast! option, good to 175 down and 10 up.
Remote desktop is unusable due to severe latency (up to 1.5 seconds) and extreme jitter. Using WinMTR I see the rural remote end has excellent connectivity -- pings averaging 24 to 30 mSec with low jitter. I verified this in person at the remote site as well, the connection there is 6 down/3 up but the latency and jitter are excellent.
WinMTR and traceroute show that the packets leaving the remote site run into trouble at the very last hop near my home at
c-73-66-XX-XXX.hsd1.ca.comcast.net Average ping: 504 mSec, worst 1418 mSec
Home modem is a Zoom DOCSIS 3.0 8x4 5431J
Downstream SNR ranges from 41.3 to 41.9 dB, power ranges from 6.3 to 9.0 dBmV
Upstream power 45.0 to 46.8 dBmV
Router logs at both ends report nothing unusual. The LANs at both ends are Cat 5, no wireless involved.
Any ideas? thanks.
