This is English dubbed Russian video of extending WiFi with proper antenna. There are series of these videos by Kreosan. They improve antennas over time. I believe they achieved range of a few kilometers. Wi-Fi frequency and chip are standard, antenna is the only component improved.
Aside from that, a much simpler antenna is this one, which can be built from a metal can + connector + wire stub. Directionality is likely a bit worse but I've used it successfully over a distance a bit lower than a kilometer. https://web.archive.org/web/20060516103023/http://www.saunal...
Made a GIF of the transit of the milky way using this software on a raspberry pi with some SDR/RF equipment. https://github.com/byggemandboesen/H-line-software
Unfortunately I only have some images on my phone right now, a git page is on my todo.
If you are in the USA, and you have the appropriate Amateur License (Tech class or higher), and you choose channels that are in the Ham Bands, Then it's perfectly fine to use these as ham radio links. https://www.arednmesh.org/

Perhaps most unusual about the pair is that in a war that has deeply divided Ukraine, where no one is indifferent, the two say they are neutral. Rather, the conflict is part of a landscape that emerges in rare moments, like the distant reports of artillery fire at the end of one video.
That neutrality is not a calculated stance to avoid offending viewers. It is one of faith.
“The lord Jesus Christ does not take sides, and we must strive to act in his image,” Mr. Kryukov said. “We study the Bible, and our members, we call them brothers and sisters, live in Russia and Ukraine. If we picked a side, we would become an enemy to someone. And we don’t want to be enemies with our brothers and sisters.”
They apparently has left Ukraine since the full-scale war broke out, and travelling around the world: Thailand, India, Kazakhstan, etc.
The fact that they have themselves fled the war zone if anything makes it worse. They are hypocrites as well as cowards.
Please.
