Alright guys, final update..
Bro @TXSim and bro @jjj2 managed to help me reset my router n modem along with its settings and finally i hve my normal speed back.
The people working at TIME call center should learn a thing or two from them.

Once again , i would like to thank them for their help !

Well, everything became back normal after resetting the router to factory default. What you need to do is that you need to insert a pin below the router ( there is a tiny hole there with a button inside ) and pin down the pin to the button for at least 10 seconds ( yellow light > blinking orange light > stable orange light > stable yellow light) .
If you dont follow the step as above, the router wont detect any connection and you wont be able to utilize the internet to insert the settings ( PPPoe username, password) into the router via 192.168.0.1/192.168.1.1.

Maxis offer the best deal for home user. 100Mbps RM129 with free calls ( correct me if i m wrong ).

100Mbps is now the basic needs for all households! Lower than that considered non-standard for our society now

Don't need to question other's opinion in such a way bro, everyone's entitled to their own measurement of what is their basic needs. I do find that your comments of 1Mbps will do it for you a bit strange too since you can't even stream HD content with that speed. Anyway hope Maxis doesn't disappoint you with supplying you reliable 1 Mbps speed at least.
