Keep getting RED logo

[PaulFromHouston]

When I first god my Ooma a couple of years ago, I had trouble getting it to work. I don't know why but it would never go blue with the wired Internet, but I got it working using the WiFi module. On occasion, maybe every few months, the logo would go red and I would unplug it and plug it back in and it would work again. But, for a couple of weeks, I just had not been able to get it to go blue. I would unplug it and plug it back in. I tried the wired connection again. No go.

Today, I made the assumption that the page key was some kind of reset function and pressed and held it for a number of seconds. And, after that, it went blue. Maybe just a coincidence since it is actually a page key and not a reset. Then a minute later it went red again. So, still thinking the page button was a reset, I did it again, held the page button for a while and it went blue again. And so far, still working.

Now that I know it is not a reset button, I'm all the more bewildered. What is going on? How can I get it working reliably again? Seems to be okay now but I don't trust it.

Is the Telo connected directly to the Comcast modem? If it is, turn the modem off. If the modem has a battery disconnect it. Turn the Telo off. Wait one minute. Power the modem on, connect the battery, and wait until the modem finishes syncing with Comcast. Power on the Telo.

Why is this necessary?
Comcast programs the modem to lock to the first MAC address it sees after power on to prevent the customer from getting more than one IP address. If you need more than one IP address you have to pay extra for it.
