BT Broadband crawling - is it just us?

[Darren B]

Same here - work is further away from home exchange and varies best would be about 3mb, home best would be 5mb, most of the time they are 2 to 4 during the day, mind you i get lag when someone logs in to the cctv system. But i i can easily run vpn's and without to much slow down. all good old fashion BT copper

Somebody here has just suggested that the BT residential service is ADSL, whereas the business service is ADSL+ . If this is true it would certainly warrant a few extra pounds a month, but anyone thinking of changing would be best to check first (I doknow for sure that the business version is ADSL+)

It's unlikely you'd ever get the full 8 Mpbs. After the overheads for protocols are taken into account it's more like 7 Mbps and that's before considering other traffic on the network.

BT did use contention ratios (i.e. sharing of the bandwidth) to get around the fact that you were sharing a backbone connection with other users. For home users this was 50:1 and for business it was 20:1 (i.e. there would be up to 50 or 20 users sharing the available bandwidth).

I don't think this is as much of a problem now as there's more bandwidth available from the local exchange to the network backbone. There is still traffic balancing to try and give everyone a fair share of what's available and at peak times they limit peer-to-peer protocols to stop everything slowing down. They also rate limit heavy users (anyone who exceeds 25GB of download in a month I believe) at peak times.

Well I am on BT Broadband in my office and get 2.7MB out of 8Mb.

The office next door is on the same line but uses ORANGE and gets 7MB, they are all of 4ft away from me.

I was told it was my line that was the problem and the quality was poor. Yet the office next door is on the same line and it doesnt affect their speeds.

BT Told me my BRAS ( huh?) at the exchange was set to 3mb.... Looks like BT are capping / throttling connections again to get more people online.

Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Well BT now reckon I have a noise level of 57db on my line and am lucky to have broadband at all. Strange how this noise doesnt affect people on Orange next door.......

[Darren B]

Odd i thought you could only have one broadband per copper line

BRAS

Broadband Remote Access Server

There is loads of information on this around the internet, but basically if you have a noisey line, then your modem will try a sync all the time to get the best speed, BT then cap the number of sync events, which results in you line being capped, thus resulting in a reduced speed
