We recently purchased an Orbi Pro mesh router with satellites to extend the WiFi coverage in our small business. We have a cable modem (Comcast Business Gateway), an unmanaged switch (Netgear Gigabit), and the wireless router (Orbi Pro w/3 satellites).
If I connect the modem to the internet port of the router, and the switch to one of the ethernet ports on the router, then I have internet connectivity but can’t communicate with any of the devices on the switch:
Modem -> Router (Router Mode) -> Switch
Alternatively, if I connect the modem to the switch, then the switch to the internet port on the router, I am able to access some websites — but not all:
Modem -> Switch -> Router (Router Mode)
At first I thought this was a DNS issue, but I’m guessing it’s a routing issue, since there’s no router between the gateway and switch.
It seems the only configuration that lets me access all websites, and all of the devices connected to the switch, is to place another router between the modem and switch, then place the second router in bridge mode:
Modem -> Router #2 -> Switch -> Router (Access Point Mode)
I feel like I’m missing something here. Is there any way I can connect the modem, switch, and single router together so that I can access the internet and connect to all devices (both wired into the switch and wireless via the router)?
The only change to the modem configuration was to turn off WiFi. The only change to the Orbi Pro configuration was to switch between router/AP mode and enable WiFi. The switch is unmanaged.
