Power off your modem and check the following:

If the problem still persist, please check with your ADSL Service Provider.

I am getting poor ADSL speed performance from my modem.

i) Ensure that the ADSL line is at least 10cm away from the Power adapter.

(see Figure C-1. Distance between your ADSL Line and Power adapter)

ii) Place your modem away from devices or appliances such as monitors, exposed computer systems (with chassis covers removed) or another modem which exhibit magnetic fields that may cause interferences to your modem line.

iii) Ensure that Micro-Filters are used for phone sockets that are sharing the same ADSL line.

If your modem speed or performance is still unsatisfactory, please contact your ADSL Service Provider.
