How to change modulation manually

Hi guys!
I need to change the modulation manually cuz my HH2B is working slowly and I've tried everything but my speed stiil very poor.
So do anyone know how to change it manually?

Thanks in advance.

It might be more likely that you have a stuck profile at the DSLAM........might be worth talking to your isp and asking them if they can retrain your line

Nope( Problem not with that cuz with other 4 modems internet connection is working fine. Firstly when I unlocked the HH2.0B it worked fine but after 2-3 hours started working slowly and I checked the firmware it was upgraded automatically but HOW I didn't get it. And now it is working but max speed on my line is 1mb.

Fair enough........not sure of the exact location but I think it is dev/ppp0

so from ssh enter the command

conf set dev/ppp0/dsl/line_mode g_dmt

conf reconf 1

then reboot

if the dev/pppo/ errors try swapping the ppp0 to atm0
