Hi all Sifus here,

I've recently upgraded my maxis fibre stock router TP-link Archer c5v to Asus AX82U.

pppoe username and password has been provided by maxis and internet is working fine on Asus now. The ISP profile in Asus router is MAXIS FIBRE-SPECIAL.


However, I'll still need the voip phone service as my home alarm system is connected to the phone. So I have tried the following method but none of them work.

1.Connecting both TP-link c5v and Asus Ax82U to maxis modem (once Asus router granted access to the internet, c5v doesn't work anymore)

2. Connecting C5v Wan port to Asus Lan 3 as per Asus's setting, (No, the voip phone and internet both doesn't work on C5V )

3.Connecting C5V LAN port to Asus Lan3 (doesnt work)

I have also tried to disable the DHPC in C5V setting, as well as enable the bridge mode. All doesn't work


Any sifu can advise what setting do i need for the phone to work?

hello, thank you for your reply

i have already called maxis, they provided how to do the configuration

they guided me to Reset tplink router and voip setting with credential, then set the router to bridge mode and connect them to asus port 3

i have tried, it doesn't work

so i call them back, another personnel says, no if you need to use VOIP you MUST use maxis router as the main router then connect asus to the maxis router

what's interesting here is, i tried to connect only tplink router to the maxis modem, and it doesnt work anymore, doesnt connect to internet and voip also dont work

tried to factory reset the router and set up from the begining by entering pppoe details, phone number etc..., it still doesnt work

After several unsuccessful attempts, i have decided to go back to the only solutions that works so far.

Which is maxis modem > maxis router > asus router. Turned off the wifi function on c5v

Since this connection doesnt impact much on my internet speed(tested, asus able to run more than 300mbps,my plan is 300mbps) and its the only solution that both internet and phone works so far.


Thanks sifuss
