Latency Problems

Hi All,

I have a problem with latency. I moved to my curent address around a year ago and had the broadband moved from my business address. I was told that the speeds would be lower because we now live in a rural location and fibre wasn't available. Things were ok until we had a lightning strike on a local telegraph pole which took out the service for a few days. When the service returned the internet started playing up, random disconnections, slow speeds etc so a case was opened and an engineer was sent out to check the line. This was over a year ago, we have now had 7 or 8 engineer visits, 5 replacement hub 6's, many line re-sets. The system became fairly stable but with random and frequent disconections, not loss of sync, just disconnect for a few seconds and then re-connect but no line problems were found, although a problem was found with the line setup, apparantly there were two numbers associated with the circuit which I was told couldn't happen! Eventualy a cease and restore was carried out which was supposed to clear any problems. We now have a download of @ 6.5mb, an upload of .5mb but a latency of 1500 or more which is causing reliability problems. Openreach have now said that it is a setup problem which BT are having trouble finding. Any ideas would be gratefully received. Here is the setup of our Circuit.

FTTP is not available.

For all ADSL and WBC Fibre to the Cabinet (VDSL or services, the stable line rate will be determined during the first 10 days of service usage.

This line is on a Market A Exchange.

In order to be eligible for handback, downstream speed should be less than Downstream Handback Threshold values.

Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises.

If the End User wishes to migrate from their current Broadband supplier they will need to contact the Broadband supplier they want to take service from to arrange for the service to be migrated.

Thank you for your interest.



While all computer networks possess some inherent amount of latency, the amount varies and can suddenly increase for various reasons


"postcode and address check results are indicative only." But you can get precise results by them. It's only necessary to search by corrects postcodes. Basically, you can do it on
