I made a screen record of the HDHR Tech stats..to show what happens to the signal metrics when i trigger interference. Just in case it helps any. And this is the state of the signal, as I mentioned above, that i notice the buffer banner come up, and the failure to recover properly.
1st trigger is the massager wand turned on and running. (Pretty much cuts everything thing.)
2nd trigger is me flipping the fan speed switch several times. (mainly cuts Symbol Quailty)
