I’d looking for options to extend my wifi coverage at home. Currently inside my one story ranch coverage is acceptable. Outside, I only have connection inside the blue circle. Router is located at the red dot.

I would like to add coverage inside the garage, which could be extended wireless or wired as I have an empty conduit available already. Garage is all metal, and the house has metal roof only.

I would also like to extend coverage to as much of the property as possible. Lot is a total of 5 acres. I’ve seen outdoor antennas which i could mount to my existing arial tv antenna. What is going to be the most cost effective method of achieving this setup?
