Doing some testing of my connection it appears something is wrong...
This is about double the normal result.

Those pings don't look out of the ordinary for a line with interleaving on (yours is set to auto). Do you want me to turn it off?
Have they changed much recently?

In that case I'd try rebooting and seeing if you see different response times on a different gateway. You really shouldn't but it's worth trying.

I then changed around the Wiring on my network and connected directly to my ADSL Modem and tested again with another Wireshark capture. Same problems.
I've just reconnected everything. I'm still having issues and I've just done another capture and I'm even getting errors browsing websites....
Just tried another machine, same problems! Would suggest a problem with my connection or setup on my machines.
Some of the errors I'm getting included
TCP segment of a reassembled PDU (MTU problem?? I'm using 1492 as I'm using PPPoE to connect)
TCP previous segment lost
TCP Dup Ack
TCP Retransmission
Would suggest packets are being lost or broken up somewhere between myself and the server

Are you using an MTU size of 1492 on both your router and your computer?

Seriously though. The reason is the modem I use works in a passive mode. The modem Syncs the line with the exchange then I connect to Plus.net from my Linux machine. The Modem is connected to my Linux machine by Ethernet so I therefore have to use PPPoE as PPPoA won't work.
I did set Path MTU Discovery but I'm guessing its not working correctly for some sites (probably their Firewall).
