So my dietpi setup stopped working out of the blue. I use Plexamp over the Internet and it's been steady until a couple months ago.

Long story short, I panicked. I reinstalled dietpi on my SD card, but then realized I wasn't able to connect my phones hot spot to it (I don't have a lan line currently) so then I just said screw it and download the bloated Ubuntu as it "just works" sometimes. Thankfully I was able to get my internet working this way albeit.

So now I'm downloading Plex media server. And things started to finally sync on the browser and it worked for like 5 minutes before all my Plex accounts started showing offline again. What am I doing wrong here? Do I really need to ask my neighbor to let me use their Ethernet connection to setup my raspberry pi? Guys is there a way I can just use a hotspot for now for this? Why is this so difficult?

To make matters worse, I was going to install rustdesk so I could plug the thing into my neighbors router again, and remote access things. But Ubuntu connection on rustdesk disconnects every 7 seconds. What do I do?
