So I’ve been having some weird disconnects happening with my internet connection ever since xFinity did some kind of upgrade and I was looking at the logs and saw something strange.

I’ve censored out the MAC addresses but the XX one I recognize as my router and none of my devices appear to have the YY one.

I looked it up on maclookup.app and saw “Harmonic Video Systems Ltd.” which is apparently a company that’s working with xFinity?

So I guess this is just telling me it’s having issues connecting right?
