Like running a coax line to your neighbor’s house so they can use your internet? Sure. A lot comes into play such as the signal strength by the time it makes it through the splices, splits, MOCA adapter and length of wire to the neighbor’s. What if you have issues from the ISP/wiring side? Well then good luck getting a service technician running that call when they see what’s going on.

There’s really too much of a hassle vs just the neighbor paying for their own connection lol.

Yeah, I’m confused why he’s being down voted. I do find Fast dot com to be inaccurate and likely that’s why he’s seeing this, but I work for an ISP and every customer is overprovisioned. It’s more common than not if testing with a capable device, especially hardwired, they’re getting more than what they pay for.
