"I'm from Comcast and I'm here to upgrade your internet."

This was the late night message from my business partner. Comcast visited one of our customers and likely replaced the Gateway.

The last time I responded to such a call, the Comcast installer had simply disconnected the coax feed from the original Gateway and installed a new gateway in a different location. Because everything is wireless now, the new Gateway does not need a LAN connection, right? (This is a Ubiquiti mesh installation with a private router) Since the user's iPhone could access the Internet and all of the cable boxes worked, the installer declared success and left. It would have been much simpler to swap Gateways, bridge the new Gateway, and reboot the customer's router, but I suppose that this concept is too difficult for installers to grasp. No one bothered to test the customer's wired Sonos system.
