We have the house pre-wired with Cat-6 Ethernet to avoid dead spots for internet access. I am no expert, but I am much more experienced and trained with computers and networking than other technical skills. I can hardwire my desktop and will have Ethernet jacks throughout, I can also plug in my laptop directly. This will keep the WiFi bandwidth available for phones and other devices without Ethernet ports. There are about 15' between the shop/garage and the house. The mechanicals room is nearest the shop (almost like I planned it that way). I will probably run Cat 6 or 7 between the buildings and the have a separate router distribute WiFi in the shop. I will hardwire the TV in the shop...need to see videos on lots of how-to stuff.
Big issues to solve are finding a good internet provider and boosting the cell signal. Given our location, my choices are Starlink or other Satellite based internet or Verizon or similar cell based. There is no fiber or DSL in this rural area. 7 miles to the nearest town and it is less than 5k people. Only about 6 properties on the entire road and the smallest is 15 acres. They are not likely to run cable, fiber or DSL anytime soon.
The cheapest solution seems to be finding a good cell booster that can effectively be my ISP. Verizon has that service. Once I get a strong signal in the house, it can run through the wires and wireless. Plan B will be Starlink with the same distribution plan.
