Advice sought regards best solution for providing ethernet to detached garage. Homeplug vs Mesh vs P2P Bridge?

[Tech9]

Wireless link is your only remaining option anyway. AiMesh or other.

And there is absolutely no way to pull an outdoor Ethernet cable on a steel wire between the two structures??

Hi Tech9,

an old thread, but, a thought here: lightning.

It's getting more common.

Research indicates that lightning strikes are likely increasing due to climate change. Specifically, studies suggest a correlation between rising global temperatures and an increase in lightning activity. Researchers at UC Berkeley estimate that lightning strikes could increase by about 12% for every 1 degree Celsius of warming, potentially leading to a 50% increase by the end of the century. This increase is attributed to the greater instability in the atmosphere, leading to more frequent and

A steel and copper wire between two buildings is Ben Franklin level lightning seeking.

This guy, the 8 Bit Guy on youtube, put a fiber optic connection between his house and the house next door.

Why? His buried regular copper ethernet cable got vaporized by lightning, along with a lot of his gear. Relevant section start at about 5:55.

The lightning struck a tree in the yard. It grounded, well, into the ground, where the electrical energy found the copper cable.

This was underground--an aerial wire is would of course catch the lightning directly.

So, for those reading later, I would recommend a fiber optic connection, aerial or buried, or, as I think was decided by the original poster, wireless. The connection distance is not far so I think that makes the best sense regardless.

Agree. Risk assessment needed. It's a short 15-20ft run, perhaps below the tree line and lightning rods, mesh or whatever other protection is installed on the roofs, common weather in the area, etc. Regular thunder storms - higher risk, perhaps not a good idea.

MoCA not feasible - No Coax

None in the house? (Reading OP, was thinking MoCA to extend wired connection to more advantageous location in the home, then extending network to garage via fiber or other means.)

Many times you don't even need a direct hit. There will always be an equal and opposite sign charge created at the surface of the earth as the cloud passes nearby overhead (can be miles away) . This charge flows into the ground/neutral side of electronics. Most of the time it is a non issue, but when feelers start being created (above air breakdown voltage) , potential for unprotected electronics to be damaged. Second is the sheeting current across the earth surface from a strike. Any resistance present will create potential difference in charge level that can overcome protection circuits.
