Now have another problem. The router installed by the Maxis installer I want to keep it at the TV area. So I put my own router (given by TIME before when I subscribed them) next to the BTU. the problem is I was unable to configure this router to make it to work.

Does anyone know how to configure TP Link AC1200 router following Maxis settings?

Yes I do have it already. I went to the config page with admin access. This TP Link have “Malaysia-Maxis” mode so when I select that it auto populate all the Vlan IDs. When I hit save, it still doesn’t work.
