So I'm seeing huge amounts of latency on my connection. Not just a few hundred ms, but pinging my local plusnet exchange often takes 10-15 seconds! It's very easy to reproduce: any time I upload anything, my line gets clogged and becomes unusable. This makes things like online gaming etc impossible, and generally results in very poor service. My download speeds aren't too bad, I can get 3Mb/s, but I never really get more than 100kb/s upload, usually closer to 10kb/s .
I have talked to plusnet support several times about this but they don't seem to understand. My line has been checked repeatedly by BT engineers and it is fine. I am fairly sure the problem is not with the line since I see very little packet loss.
This is a typical ping report against my local exhange:
Ping statistics for 195.166.130.216:
Packets: Sent = 48, Received = 47, Lost = 1 (2% loss),
Approximate round trip times in milli-seconds:
Minimum = 70ms, Maximum = 17820ms, Average = 1097ms
There were no lost packets (except the last one when I interrupted) but at least one packet took 17 seconds to arrive!
I don't see the same delay on my internal network (e.g. pinging another computer conencted to the same router) so I don't think it is a problem with my router.
So I am almost certain that this is a problem with plusnet's exchange.
Perhaps I am on the receiving end of traffic shaping?
After many calls to plusnet and listening to hours of awful 90s hold music they made some changes, sent me a new router and things were ok for about a month. But now the problem is back! It's frustrating because I know it can be ok.
Does anyone know how to fix this?
