is that an OOMA fix ?

or

an ISP come out to my residence and fix type of problem?


If the quality is still bad with the ooma disconnected, then it is not an ooma problem. It could be your ISP, your modem, your router, or the wiring within your house.

Well there is your improvement
Now attach the ooma to one of the router's ethernet ports and run the test again

ok will do, thanks for the advice along the way.

So is my OOMA hub faulty , why would it bring it way down like that.

posting results with OOMA behind the router in a sec as soon as I can get it to turn Blue.

Describe your entire network in detail, something is not hooked up correctly.
Before you do that, log into the ooma hub and set both QOS values to 0. That disables QOS in the hub. Then rerun the tests.
