Yeah for large folders and stuff probably better to use SFTP or WebDAV

Localsend works great for me.

True, modern hardware can easily route 10gbps or more though so for most of us that won’t be an issue. Often OpenWRT on consumer routers struggles to route even 1gbps.

I agree on the external AP, that is needed.

Yeah start with pass through, without that no physical hardware will show up inside the VM

If thats what your needs are. But proxmox has nothing to do with the hardware being better.

It’s a handy router OS, why not?

Consumer router hardware generally under performs a lot, so running your router on better hardware solves that.

It would be fun as an experiment, but often using wifi adapters as an AP generally doesn’t work that well. Most of us are running an external AP such as Unifi hardware.

As far as getting this working, have you done the passthrough setup on the VM for the wifi adapter?

And have you confirmed that OpenWRT supports your wifi adapter?

Thunderbird on Android should support push, have you tried that?

I’d say the easiest is installing them using Docker, with a reverse proxy in front. That way you’re not mixing multiple services into the same database and stuff like that.

You don’t need any guides for it except for really niche cases.

For example Ubuntu VM; click create VM, choose Linux for the type, click next a bunch and choose your ISO image, CPU cores, and RAM. And you’re done, there’s no specific settings to use.
