hmm, I'm concerned about a study that has a 100% number.

I have a home Wi-Fi infrastructure and a >1G xfinity plan. I don't have a
Wi-Fi bottleneck because I use a 2.5G wired fronhaul with a 4 port
proteclli vault pro connected to 4 Wi-Fi 6e APs that are located properly
per spacetime.  I didn't need to consult with anybody nor get others
agreements to do this. As a homeowner, I did it all by myself. Wi-Fi has
never been the problem since doing this despite the 100% claim.

I treat communications like an essential service. I don't run all my
electrical devices from one single extension cord. Probably time for
homeowners to think about updating their comm infra and treat it as if it's
a critical service because it is.
