BT still capping 8meg maxDSL lines at 2mbit..


ABRAHAM LINCOLN GOT IT NEARLY RIGHT WITH THE Gettysburg address. He just missed out the bit about the self-evident truth that whatever BT called itself, it would still be crap. While the GPO was halfway-decent, as soon as the telephony bit was spun off to become British Telecom, it all went pear-shaped.

Earlier today, my ADSL line was upgraded to ADSL Max by my ISP to 8Mbps from 2Mbps. The line was retrained and reports downstream 8128kbps, upstream 448kbps. Hooray, I thought until I realised I wasn't actually seeing a four times improvement in performance. Then I actually ran a test on the line. The results were interesting.

As the linked article explains (and seveal others in similar threads discussing this very topic!) this is a problem with BT not detecting the higher sync speed and releasing the speed limit.

What you can do is plug a normal phone into a phone socket without an ADSL filter, unplug your ADSL equipment from your phone socket, wait 20 minutes, reconnect it and make sure it syncs at a different rate then re-filter your normal phone, disconnect your ADSL line and reconnect.

This may then force BTs equipment to recognise the new sync speed and release the speed limit on the line.
