PrusaLink MAC not stable, local host name not allways working
Powering up the printer and after Prusa Link boot, I had a message No lan access. I switched off and then on the printer, but after new boot I had the same message. A Scan of my LAN with Advanced IP Scanner, verified that Prusa Link had not been connected. As I was searching the internet for a solution, sometime I saw the message Prusa Link OK. Trying to connect with the hostname I have ginven to it at setup, there was not any connection. And the IP that I have reserved in my rooter for the printer MAC was not the same as before. Checking again the LAN, I found that printer has changed MAC! I configured my router with the new MAC, but still unable to log with the "server" name. So I had to log using the IP.
Then I set up my router for the 2 different MAC addresses to have 2 specific IPs, in order to do not search each time for the random IP assigned by the router. Some times I can see PrusaLink by the "server"" name, some others I do not.
Do you have an idea what could be wrong? Is it normal to change MAC address, and how I can prevent it?
I have seen that there is a file in the Linux area of SD card that can be edited to assign a fixed IP (but not MAC), and set everything for PrusaLink. But my PC is running Windows 10, and the Ext2 Volume Manager can read the files, but not edit them (because they are "protected"). Can I set these options with a file in Windows area of SD? If not, is there any way to "unprotect" the filew (or folders) I want to edit from Windows? This could be very helpfull, because there is another bug in Prusa Link. If by error a is uploaded a file that is not gcode (for example an 3mf one), there is no option to delete it.
