@Neal_C maybe MoCA is they way to go? But you still have to put down cables in the ground.

MoCA Technology StandardsMoCA 1.0 has a maximum distance of around 300 meters (984 feet) and supports transmission speeds of up to 135Mbps. MoCA 2.0 has a maximum distance of around 185 meters (607 feet) and supports transmission speeds of up to 1Gbps. MoCA 2.5, the third version of MoCA, has a maximum distance of around 500 meters (1,640 feet) and can support transmission speeds of up to 2.5Gbps.

Or Ethernet standard.

A single run of Ethernet cable is designed to work at a maximum of 328 feet or 100 meters. It's entirely possible to exceed the manufacturer's specification and still maintain network connectivity. However, this greatly increases the chances of connectivity issues, reduced speeds, and lower reliability.

tp link powerline standard:

The maximum distance range is 300 meters. However, with noise, interference, and line quality the range the powerline adapter can reach may be reduced.
