I've noticed in the past week or two that when I visit speedtest.net, the 'ping' result is often around 120-150mS. It always used to be about 50mS. I do have interleaving enabled.
When the ping response is bad (>120mS), if I go to the DG834GT's 'connection status' and disconnect/reconnect from demon (leaving my actual DSL connection connected), I nearly always find the ping response is much better - back down around 50mS. So, I have two questions...
1) Is the above indicative of anything worriesome wrt demon's general service provision?
2) Is there any recognised 'reasonable' limit on latency and, if so, what would be 'unreasonable' (with interleaving enabled) to the point of being worth complaining about?
I don't do any real-time gaming, and I don't use VoIP, but I'm inclined to think that kind of latency (>120mS) would render either gaming ot VoIP a bit useless.
I can ping known UK-based servers from the command-line, and I get results consistent with speedtest, so while speedtest.net is obviously not 100% reliable, I don't think that explains the issue.
