I've had Ooma for about 3 years. Recently I've had trouble with it dropping and eventually reconnecting. I replaced my unit and assumed it was bad.
Installed the new one.. same issue... on with Ooma support and they send me yet another unit. Same issue...
Bought the wifi module in hopes that type of connection would work better. Guess what, does the same thing. Steady blue, can make and receive calls. Less than a minute later blinking red. This happens non-stop.
So what is the issue?
You have to download and install an app to run the full test.

I did make some progress. I took out my old Asus router and hooked it up. The ooma device connects fine. So something has changed on my newer Asus AC68U router. To my knowledge, the only thing that has changed is the firmware.
I attempted to downgrade the firmware but Ooma still cycles as before.
So at the moment, I have my Asus N12D1 router hooked to my cable modem, the ooma hooked to that and my AC68U as my access point for 5gz wifi and connected to the N12D1 via ethernet.
Not sure what has happened and I will research it more. It is odd that I can't find anything on Google about specific issues with Ooma and Asus newer firmware.
I'm starting to think the ooma device doesnt like anything over 100mpbs... ?
"SIP ALG - SIP Application Layer gateway is a feature in most routers and is supposed to help SIP based calls when going through your home or business router. Unfortunately it causes more harm than good. Make sure the VoIP test indicates N for NO. If it is Y for YES, try and disable it in your router as per our article on disabling SIP ALG."
It's worth looking to see if your router has this setting, as another user on THIS forum recently reported it having caused him problems.
