A step-by-step plan for swapping out the Hawaiian Telcom box for your own UniFi Dream Router 7, without losing TV.
Right now, plugging the new router straight into the ONT doesn't work on its own. That means Hawaiian Telcom needs to give you a username and password for the connection, and possibly one more code called a "VLAN ID."
There's also a wrinkle: since TV service is bundled in, Hawaiian Telcom's own rules say their box is required to make TV work. That doesn't mean this is impossible, it just means you need to ask about it directly on the phone call in Step 1 below.
Call (808) 643-3456. Tell them you want to use your own router instead of renting theirs.
Sometimes you can find this information yourself, straight from the current Hawaiian Telcom box, before it gets unplugged.
192.168.1.1) and a password printed on it.This only works if there are two separate boxes (one from the fiber into a small box, then a separate router box). If it's all one unit, skip this and go back to asking Hawaiian Telcom on the phone.
If it doesn't connect: double check you typed the password exactly right (it's easy to misread a letter), and try it once with the VLAN ID and once without, in case you're not sure if it's needed.
Hawaiian Telcom's official policy actually does allow using your own router for internet, no extra charge for doing it. Here's the exact wording, if it helps to read to a support rep who pushes back:
"The Hawaiian Telcom provided gateway is recommended for High-Speed Internet customers although customers may choose to use their own gateway."
"The Hawaiian Telcom provided gateway is required for Hawaiian Telcom TV customers and cannot be substituted with a customer provided gateway... Use of a customer provided gateway will result in technical issues including complete loss of TV service that cannot be resolved until the gateway is replaced with the Hawaiian Telcom provided gateway."
In plain terms: internet-only is fine to swap. TV bundled in is where it gets complicated, and worth asking about directly rather than assuming.
Nobody online has posted the exact username/password format or VLAN number Hawaiian Telcom uses, that's just not public information. That's the whole reason for Steps 1 and 2 above.
