The ZyXEL P660HW-T1 v2 routers sometimes do not do ADSL2+ full speeds and Annex M in their default configurations.

Here is how to modify the router's configuration in order to get the best speed out of your BT or TT ADSL2+ line:

ADSL2+

Sometimes the router reports ADSL2 DELT mode, and has low sync rates (~7 meg) on a line that can support more. The ADSL2 DELT is a red herring. This is a 7.1 meg max sync.

Telnet in, then type:

sys edit autoexec.net

Press "i" You should see a colon When you see the colon, type the following command:

w dmt2 set largeD=2

Press enter, then press "x".

You can verify that autoexec.net contains the new command by typing

sys view autoexec.net"

After a reboot, the sync rate should be increased. This only applies to the T1v2.

Annex M

The router does not do Annex M by default; it needs forcing.

Telnet in, then type:

sys edit autoexec.net

Press "i" You should see a colon When you see the colon, type the following command:

wan ghs set annex m

Press enter, then press "x".

You can verify that autoexec.net contains the new command by typing

sys view autoexec.net

After a reboot, the upstream sync rate should be increased, at the expense of some downstream.
