Title: Latency Spikes
Post by: CBailey on Jun 21, 2012, 12:23:53
Afternoon all,

Hope someone may be able to offer some advice as to an issue I am having with my internet connection at the moment.

I have recently just had BT openreach out who have fitted a new line from the pole to my house to resolve an issue which was causing my connection to drop constantly and was also causing a lot of noise on the phone itself. IDNet also performed a SNR reset directly after.

Since this work has been done the internet connection itself has been absolutely fine from a speed and no disconnects perspective. Its Sync'd at about 6000Kbps IP profile of 5.5Mbps. However I am getting latency spikes every few minutes which last a few seconds and then clear. I only notice the issue when playing online games, however I am happy that the issue is not with the game servers as Ventrilo voice comms will also spike at the same time. This morning I tried running a looping ping test to idnet.net while replicating the latency spikes and the ping response time will jump from around 29-32ms up to over 600ms. I also ran pingplotter with a tracert to idnet.net and again hops will jump from 30ms average to well over 1000ms.

I have noticed that if I run the ping test and tracert but no other WAN traffic the issue does not appear to occur other than the odd 150ms ping here and there. So I assume the issue only occurs when there is a moderate amount of traffic on the network.

I have disconnected all other devices from the network, router is brand new having replaced it trying to resolve the line noise issue.

The only thing I haven't tried yet is to hard wire the PC to the router via the ethernet connection but I don't believe the issue is wireless related as I am getting a strong 100+ mbps connection.

Any advice on this issue is welcome, no matter how obvious or stupid it may seem  :)

I spoke to IDNet support this morning about the issue and they seem to believe it was likely to be a fault at my end although no tests were run so this is based only on my description of the problem.

Thanks

Colin

Colin, do you get the same spikes if the you connect direct to the test socket behind the master socket faceplate?

Hi Glen thanks for your reply.

I haven't tried to be honest. The whole socket setup was completly replaced as part of the above mentioned repair by openreach a few days ago so it would be nice to think this shouldn't be an issue.

I will try this tonight when I am home from work. Assuming this doesn't alleviate the issue is there anything else you would suggest?

Thanks again.

Colin

Colin,

Connecting to the test socket removes your home wiring from the circuit, so if it is still happening, then it's from BT's side.

Boot into safe mode, or use a Linux live cd, and repeat the tests.

Use a cable, not wifi. if the problem ceases, set you router to use a different channel.

Whilst keeping all fingers crossed I think this may have been a wireless issue. Bought some powerline adapters and not had the issue since.
