Plug your Ooma's "To Internet" port (called "Modem" port on the older Hub hardware) into a router LAN port. Plug a phone into Ooma's "phone" port. Power up your Ooma. Wait until your Ooma comes online - all blue.
At this point, everything should be operational; phone(s) connected to Ooma's "phone" port should work like a champ.
More things to do if you want your setup to be optimal:
- Connect a (wifi turned-off) computer to Ooma's "Home Network" port (called "Home" port on Hub) using ethernet cable.
- Do the "Change the Ooma setting to Use Built in INTERNET Port MAC Address or Modem Port MAC Address" portion of this post: viewtopic.php?t=9536#p66155 But don't need to power cycle all devices after "Update."
- Disable QoS: within http://setup.ooma.com page, select "Advanced" on the navigation menu and look for the "Quality of Service" section on the page. Set both Upstream Internet Speed & Downstream Internet Speed boxes to 0 (and Update).
- Setup port forwarding rule within Ooma setup page so you can access http://setup.ooma.com without having to connect your computer to the "Home Network" port ("Home" port on Hub) in the future. viewtopic.php?t=11921#p83732
- Leave your Ooma's "Home Network" port empty; don't connect any computer or anything else to it.
- Get to your router setup page and configure QoS for your Ooma device (have router give your Ooma high priority); need to consult your router manual for this one (either based on MAC address, reserved DHCP IP address, or LAN port #).
