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.
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 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.
