I have just finished setting up ooma Telo. I have a combined router/modem, and so I
chose Option 2b. The connections are: (1) Home Network Switch > Telo Home Network input,
and (2) Telo Internet output > router/modem.

Although the connections work well, I can no longer access the router/modem by typing its address
(http://192.... etc) to make changes in the settings. If I remove Telo from the configuration,
it is possible to access the router/modem settings in the normal way.

The router/modem is a Motorola SBG900 and the switch is a standard Netgear which connects to
two computers via ethernet cable and a third via the home wiring.

Any suggestions would be appreciated.

Your setup has replaced your internal LAN IP range with the 172.xxx range used by the Telo. Thats why you can no longer access your modem/router using the 192.xx range.

Yet another example of what I've be saying all along in various threads. The Ooma device should be used as a VOIP device and should NOT be used to replace your router/modem functionality - regardless of what anyone tells you.

Revert to your original modem/router/LAN setup, then plug the Ooma into a port on your switch via its INTERNET port and don't plug anything into the Ooma HOME port. Disconnect everything from the power and power them all up in the modem/router, switch, ooma sequence.

Read this thread for some help with configuring your setup.

The Home Network Switch in (1) should directly connect to a LAN port on the modem/router combo, not the HOME port of telo.

The telo HOME port should be empty. When you need to access telo setup page, temporary connect a pc/laptop to its HOME port and go to setup.ooma.com

Many thanks, indie_dev, for the clear response. I appreciate the step-by-step, and the explanation of why I lost contact with the modem/router.
