I have a D-Link DIR 835 router. https://duckduckgo.com/?q=D-Link+DIR+835
I've been sharing my wi-fi with my old Luddite neighbour on the top floor of my place. He can only pick it up in the front of the building.
I want to turn of the wi-fi radiation in my place again but run a long cat-5 cable out my window, and mount it up somewhere with a wireless thing there. That way he, and maybe my other neighbour(s), can use my wi-fi for free. I have no idea what that wireless thing might be, or if we'd need to waterproof and/or disguise it as a bird house or what.
I don't know how to do this, but I would like to share free wi-fi to anyone, without password - but 1) I also want to firewall it securely from my own use and stuff, 2) I'd want to monitor how much is being used, and 3) I might like to throttle it if necessary.
I've also considered building a Free-NAS router with an old computer and a few old hard drives to cache everything for less redundant traffic. I figure the Free-NAS would be far more custom configurable than the D-Link. https://duckduckgo.com/?q=Free-NAS
We're supposed to be getting fiber this year. If I can get a bunch of people in my building and the apartment next door to pitch in, maybe we can all share a line or few (somehow) with our own VPN (somehow), and provide free wi-fi to the neighbourhood too (if possible). They may have to wait out contracts or whatever, but over the course of a few years I'm sure other folks might join in. With combined contributions the expense would be less than all for themselves, and eventually we might be able to set up a decent server and service with backup batteries, etc.
There's a lot of dreamy wishful thinking in here but any leads are good on technologies, softwares, tech co-ops etc.
