High Latency

Since March I have been struggling with very high latency problems. Ping times are often above 500ms. I have had my virgin router replaced and it has not made any improvement. I am at a loss, I excepted this back in March with obvious increased demands on the network. But 9 months on with no imporvement I a loosing the will to live!

Re: High Latency

If possible can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Please post a 'Live Link' to your BQM on here straight away.

Instructions for posting BQM Live Link

Under your BQM graph are two links in red.

Click the lower link (Share Live Graph) then click generate.

Copy the text in the Direct Link box, beware, there may be more text than you can see.

On here click the Link icon (2 links chain to the left of the camera icon)

In the URL box paste the link you copied and in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.

Re: High Latency

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then Advanced Settings > Tools > Network Status.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.

Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Re: High Latency

Some of those power levels look a bit high on the downstream.
