I have a strange problem. Just signed up for streamyx and activated my account. When first turn-on modem and pppoe login, margin shows

ds 31dB
us 26dB

But when I want to browse or doing ping, i get time out error and my margin status now shows

ds 31dB
us -24dB

my line attenuation are quite good at ds 8-11 and us 1-2.

Any idea? Have not call tm tech support yet but will be calling by tonight if not able to resolve.
