How can I create a Lemmy instance without coding or the use of Ethernet/router wiring?
My Abuelo says:
he will not rewire things with the router
he wants me to find a way to create a Lemmy instance without Ethernet, just the regular Wi Fi connection without a router or anything.
This rules out what I was going to use, Yunohost. While I have the USB, I don’t have the router (it's full), switch, or Ethernet Cable and Abuelo doesn’t want to buy one nor does he want me to buy one.
He thinks it’d be less time consuming if I found a way to self-host without that stuff, just through Wi-Fi, and I don’t know how to program.
Uh, don't?
You want a Lemmy instance - that I presume you would want to be somewhat reliable - without doing anything? WiFi prioritises convenience over speed and reliability. So, things will randomly fail.
I guess pay for a Lemmy instance provider. Probably the easiest. But this is self hosting, and it sounds like you want a place to start and have chosen "hosting a Lemmy instance" as your learning ground.
Something like cloudflare tunnel will let you punch through a firewall without having to mess with network stuff.
A docker compose stack makes things as easy as they can be in such scenarios.
These are terms you can google "Lemmy docker compose cloudflare tunnel"
If you know nothing about servers, linux, docker, postgres, reverse proxies, networking, https, certificates etc. then you may not be able to do this without studying these topics significantly and practicing setting up more simple services (like a plain HTTPS server with Let'sEncrypt certificates.)
WiFi is just Wireless Fidelity... A play on HiFi. It's just a wireless equivalent of wired ethernet. You still have an IP address, you still have a router (without a router only one device in your house could connect to the internet, typically your wireless access point is a combination router with a wireless access point in it).
