It used to be happened few times a week, now is getting worse and happening few times a day. I can't even make any call in the whole Sunday (1st Nov 2015) evening.

Any expertise advices and troubleshooting are appreciated.

Any resolution suggested?

Try check your splitter, its better if you have a new one to check if the one given to you is broken.

Have resolved the issue by getting the new modem replaced FOC by TM.

According to the technician, sometimes such symptom is due to the adapter failure.

In summary, replaced with new modem and managed to get bill rebate of RM70++ for the outrage period.

Yes. it normally modem problem. Sorry just saw your post .

It's alright.

Lesson learnt and my modem life has been extended to another few years running 24 X 7.
