Your PC -> ethernet cable -> that Plus.net router thing -> BTOR modem -> wall socket
That's your setup, right? Preferably using one of those fancy twisted RJ11 cables and with nothing wireless in sight and definitely not next to a 50" plasma TV or your DVD player or anything else?
If we ignore your one (presumably anomalous?) result where you had 40% packetloss to your own router (?!), you appear to have the worst connection I have ever seen! Is your in game ping similarly bad? Do you play any games which report the actual ping and not use one of those stupid meters? Quakelive reports the ping and draws you a 'netgraph' so you have something to blame immediately when you get fragged!
Are you familiar with gateway hopping? You may want to try it. I would be raising this with PN and throwing all my toys out of the pram in the process tbh. You might well be going through one of these choked MSILs in Manchester/Birmingham/Sheffield though? Either way, ask PN for exact clarification on where your issue lies. I'm sure they will be very helpful but you might want to see the full, intrusive, service test result for your own info.
There is absolutely no excuse for gamers to be suffering in times of congestion. We are almost certainly the ISP ideal-customer in terms of bandwidth and that's kinda the only thing that they pay extra for, surely? That said, who knows at what point in the network they start classifying; after exiting the BT MEGA CORE WHERE CONGESTION NEVER OCCURS AND LATENCY DOESN'T DOUBLE OR TRIPLE FOR THE LOLS.
