New user of Ooma. Phone service works fine, but is causing the internet to go down sometimes. This has been happening ever since installing Ooma. My internet setup has a combo router/modem unit. Have unplugged and restarted the router/modem, as well as, Ooma Telo unit. Been experiencing this for 3 weeks now. Any ideas?

Is your computer connected directly to the modem/router and not to the Ooma Home port?

To help stabilize your Ooma Internet connection turn off MAC address Spoofing, which can cause dropped calls, garbled voice, and other problems, by doing the following:
If your Ooma device is connected Modem-Ooma-Router, access your Ooma Setup pages by typing http://172.27.35.1 in your computer browser window. The Ooma Setup pages open. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem and the Ooma Device. Repower the Modem. When the Modem is done booting repower your Ooma device.

If your connection is Modem-Router-Ooma or Modem/router-Ooma, temporarily connect a network cable from your Ooma device home port, to the wired LAN port of a computer. Temporarily turn off Wi-Fi in the computer, if turned on. Reboot the computer. Access your Ooma Setup pages by typing http://172.27.35.1 in your computer browser window. The Ooma Setup pages open. Click on Internet, go down to INTERNET Port MAC Address: and change setting from Automatic to Use Built In. Click on Update device. Remove power from your Modem (or Modem/Router), your Router (skip to Ooma Device if have Modem/Router) and Ooma Device. Repower the Modem (or Modem/Router). When the Modem is done booting repower your Router (skip to Ooma Device if have Modem/Router). When the Router is done booting, repower your Ooma device.

Also change Internet connection to DHCP and this works like a charm. Thanks Thunderbird!
