@gregnaimo3 . To keep the VOIP service, there are no changes to the VR1600.
From the Orbi manual:
To set up the Orbi router as an AP after you set up your Internet connection:
1. Use an Ethernet cable to connect the Internet port of this router to a LAN port on
your existing router or gateway.
2. Launch a web browser from a computer or mobile device that is connected to your
Orbi network.
3. Enter orbilogin.com.
A login window opens.
4. Enter the admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. The user name and password are case-sensitive.
The BASIC Home page displays.
5. Select ADVANCED > Advanced Setup > Router/AP Mode.
The Router/AP Mode page displays.
6. Select the AP Mode radio button.
The page adjusts.
7. Select the IP address setting:
• Get dynamically from existing router. The other router on the network assigns
an IP address to this router while this router is in AP mode.
• Enable fixed IP settings on this device (not recommended). Use this setting
if you want to manually assign a specific IP address to this router while it is in AP
mode. Using this option effectively requires advanced network experience.
(Assign a fixed ip address, say 192.168.1.2 so you can easily login to it.)
Note: To avoid interference with other routers or gateways in your network, we
recommend that you use different WiFi settings on each router. You can also turn
off the WiFi radio on the other router or gateway and use the Orbi only for WiFi client
access.
8. Click the Apply button.
The IP address of the router changes, and you are disconnected.
