Summary: my connection has extreme jitter
IP address 62.252.212.113 is the second hop on my internet connection
traceroute to 194.168.8.100 (194.168.8.100), 30 hops max, 46 byte packets

The following output is produced by the command

This command is run directly on my router which is connected directly to the HUB 4.0 with a cat6 cable
Each line represents the stats for 100 pings to my second hop and this is therefore the averages for a total of 800 pings
The jitter is extreme. In some cases roundtrip time approaches 800ms, which is enough to go to Hong Kong and back four times
Latency to the second hop on my internet connection should NOT be so high
My modem log shows no errors and all power levels are within spec. The modem has been restarted by VM support several times already
My router is NOT the cause. I have a second internet link connected to the same router and roundtrip times out of this link to any ip address are constant with minimal jitter, and in the UK, below 10ms
I have spent about one hour on the phone today to VM support. Even the second level support staff are clueless, just offering to reset my modem and then telling me that "since the speed is ok your internet link is fine; it has no problems".
Nonsense. They don't even seem to comprehend the concept of latency and the evidence above indicates there is clearly a problem.
Are there any competent VM support staff accessible via this forum who a.) can comprehend the problem and b.) can assist in diagnosing the cause?
