Hi All,

I have been having sporadic issues with my internet. A couple of times a day, when we are streaming on demand TV, it will pause and the buffering circle appears. After a minute or so it will sort itself out and continue.

I have noticed that when this happens, pinging the Google DNS server (8.8.8..8) I get massive ping times usually between 1,000 and 5,000 ms! Looking at this in more detail over the past few days I have run a couple of tests
1. Continually ping'd 8.8.8.8 over 24 hours. Looking at the log, the issue seems to happen a few times an hour
2. I have run traceroute 8.8.8.8 for a few hours and I have a few instances of the long ping times. I have pasted the traceroute for the 3 occasions below (changed my internal addresses to "MYIP")

As you can see they vary a little and also the impact of the overall ping differs (e.g. the third one has a good end to end ping time but the intermediate ones are poor)

Anyone have any ideas how to trouble shoot this? When I spoke with the ISP, they said that they can not work on ping times only run the line tests. I am trying to get to a point where I can give them something concrete to go on. Also, are there any good forums out there for these sorts of issues?

Thanks

Lee.
