Some additional information, which you may wish to add to your excellent page on the use of DMT with this router -
You can tweak the target margin of this router using DMT. You can turn the PC off and you CAN RESYNCH SUCCESSFUILLY,
BUT DO NOT REBOOT OR TURN OFF THE ROUTER OR THE MARGIN WILL GO BACK TO BT's SETTING OF 15
and it will be another 3 - 5 days at least before you can return to a decent IP and download speed.
