pathping would give more appropriate information than tracert
This is what it should look like:
This shows no packets were dropped.

This shows no packets were dropped.
HI Neil,
We don't see any packet loss on our network. Are you getting any errors reported on your router? Are you able to try a different router? Is it connected via ethernet or wireless?

Hi Jojo,
I've tested with three different computers (2 desktops connected via wired Ethernet, 1 laptop via WiFi), 2 different routers and they were connected via the test socket behind the BT master socket faceplate.
What's the packet loss showing on the pathping then? I have been running that on a regular basis over the past couple of days, and it always shows similar results. The same with pingtest.com, always showing 2%-8% packet loss and a lot of variation in ping times. I've just this morning started an external ping log to my router, and the current results are shown on the attached graph (around 12:30 I was downloading some large files for about 15mins) and as you can see there is constant packet loss being shown. Except for downloading the files, broadband was being used very little during this period, and so few to no lost packets should be seen.
I've done my best to eliminate a problem at my end, and can't think of anything else to do here. It's really frustrating, as my line stats are good, and speed seems mostly ok (upload lower than normal), but the packet loss is cause havoc with time sensitive applications, and some activity just stalls or hangs - so web pages that just never complete loading, or files that you have to restart the transfer for, or streaming that just stops, etc.
None of this was evident until a week ago
Cheers, Neil

HI webwisehost,
Can you run ping-t to that server and leave it running for about 5 minutes (Ctrl+C will stop it) I'm just going to check some other settings for you.
