Trying to help someone with a nasty case of bad latency over the BT portion but his speed is ok.
His ISP has told him they can't raise a fault because the line is within specification (ADSL2+)
I know that packet loss in excess of 5% constitutes a fault but are there other metrics such as latency?
Not afaik, Mitch, as interleaving is used to stabilise a line as part of DLM.
Hmmm his latency is in the 300 ms area indicated between his router and the ISP's edge router which suggests exchange congestion.
Just looked at his post now and he says he's got a lot of DOS entries in his router log which suggests he's being repeatedly port scanned which of course would cause issues.

Netgear router by any chance?
By the look of the logging format I'd say so.

While you say 'Netgear router' not
all do that, since we discussed pings not one Dos, as I said maybe a couple a years, so the newer performance ones ones have better logging I would say... :)
When a connection has very high latency the port that generated the request may well have closed before the response arrives. The router firewall will decide that this is a potential threat.
