It is using UniFi infra but have been on Maxis since day 1, didn't change ISP from UniFi or anything. Probably the TM technician did it since day 1.
How to login to the BTU?

Depend on what type of BTU, but generally need to set static IP on PC, then logon to the BTU address, e.g. 192.168.1.254, key in the correct username and password. Some of the BTU like Huawei, you need to disconnect the fibre cable otherwise cannot access the web GUI.
No matter what, there is not much things you can change in there, as TM does have the ability to override the settings according to what is provision on their end.

Probably the guy screwed it up or I screwed it up when I changed to my own router?

Anyway, it was all good for 3 years, no frequent disconnection until recently.
It could also be that the technician update some settings remotely, who knows. but then other providers riding on Unifi infra will always be on port 2, 3, and 4.
