I’m running 2 15ft cat 7 cables at 10gbps without issue (my modem is in one room of the house and the wifi router one room over for best coverage)
We can have 5 people sharing a 600 mbps internet service with two people streaming Hulu while two people do web video conferencing without missing a beat ... after I installed the Ethernet bridge between the wifi mesh nodes (with Ethernet cables strung through the house connecting 3 child nodes from the bridge with the 1 parent node). The nodes weren't connecting wirelessly, perhaps with all of the duct work in between the floors. And Ethernet connecting through a hub is fine when it's just the wife and me. But when other folks stay over, the bridge was needed to greatly reduce the network collisions, even though all of the child wi-fi nodes talk to just the parent node and not each other.
The only drawback is my internet service has gone down when the grid power went down about 5 times in the past 7 or 8 months, while the home had power. I'm tempted to sign up for Starlink for that alone.
