I’m trying to get internet to my office that is about 100 ft from my house. My house is about 120 years old. There are two circuit boxes that are connected. The old box is a 100w box connected to the newer 200w box. The outlets near the router are wired to the old box.

Also the office is wired into the new box into 1/2 of a 220 breaker. Don’t know why the electrician did that.

That layout looks like a recipe for disaster. Powerline signals find it hard to cross all those junction boxes without losing signal.

My setup is similar to yours. Ancient house with its own fuse box and isolator feeding a separate building with another fuse box. Powerline works but too slow to be usable.

Then there is the 100 feet distance. LAN can stretch that far, but probably not Powerline or regular wifi.

In my case, I went for a separate Internet service and phone line for business use. All tax deductible.
