Every few weeks I find myself unable to connect to my OctoPrint. When I check my router it says that OctoPrint is not connected to the wifi after these few weeks. Everything works 100% fine until the fateful day where I click the on button and it doesn't work. All lights are turning on and blinking as they are supposed to. It does the standard printer boot up with fans turning on and whatnot. I have tried using different networks and an ethernet cable. I can only get access again after re-flashing the micro-sd card.
I am running it off of a Raspberry Pi 3B+.
