I am not well versed on how the intricacies of how the technology behind wifi works but I do think that as long as you have a good strong signal from your wireless access point at your doorbell location, then even if the doorbell did have a weak wifi signal it would become irrelevant because your wireless access point is carrying all the "weight" of the wifi connection. This is why its important to test the output of your router (or access point) where your doorbell is installed. You can do this with wifi analyzer apps on your cell phone. I like to use netgear genie for mine.
But im not sure if this is wifi related. If you see fluctuations in wifi performance, then Im wondering if their is something else at play that is causing the issue. Frequent disconnections should not be happening either. The first thing I check on with things like this is power. If your transformer is good, you should be reading about 18V or higher at the doorbell wires with no doorbell connected. Why 18V? Because if you have a 16V transformer, it usually spits out higher voltage than 16V to take into account voltage drop due to cable distance and load. Sometimes they will put out upwards to 20V right at the transformer. If you have a multi-meter, i would check it at the doorbell wires with and without the doorbell attached and let us know. As far as the ring goes, I do think this doorbell uses more juice than the ring.
