Don't confuse modem and router yeah.

If you want to change to deco M5 you shouldn't have to touch the modem (huawei, ZTE, FibreHome) box

Connect your deco to LAN 1 or LAN 2 of your modem depending on infrastructure (1 if on Maxis infra, 2 if on TM infra , then select the VLAN properly for your infrastructure (maxis tm or maxis self)

If you do want to mess with the modem itself, it has no DHCP server so you have to manually assign IP to reach it

Anyways, since it did work before it's odd it stopped 2 weeks later.
