My wife and I bought a house 3 houses down from my in-laws. I'd like to share our internet service with them rather than pay for two accounts. How can I share our wifi signal with them? My Linksys WRT 1900 AC router (gen 1) is not even strong enough to reach their backyard, let alone penetrate the two other houses between our house and my in-law's house. There is a shed in their backyard with electrical power that can maybe be used as a relay for creating line of sight. But I am not that tech savvy. Would I need a repeater, bridge, etc? Is there directional antennas that I can use that would be able to send the signal to the shed and then from the shed to my inlaw's house? Would a directional antenna on my router mean that it might not transmit through my own house? Can I transmit both 2.4 and 5 Ghz or will the 5 ghz signal be too weak? Thanks in advance for any suggestions.
