RE: Original Prusa MINI & MINI+ WIFI Troubleshooting.

Hi all,

Best regards

Is it a USB3 stick? As I already mentioned, USB3 can make problems with 2,4GHz networks as it is used by the ESP module. What you should test: Check if it gets better when you use some aluminium foil around your USB stick. Or better: Try a USB cable as an extension and wrap the cable and the stick in aluminium foil. If it's getting better, then you know what to do: Take a cable and increase the distance of your stick to your esp module. 

 

I have no problems, but I'm using a USB2 stick and a cable to be able to insert the stick right next to the display.

I tryed 3 different USB sticks ( one was the original one which came with the printer) and I also tried a USB extension with aluminium foil. So far all the same. I will try a different ESP Modul next week.

I installed a replacement module today from the same supplier and now it is working. Seems that the previous one had some kind of defect.

Best regards

RE: Original Prusa MINI & MINI+ WIFI Troubleshooting.

I have a same problem from 4.4.0 to 4.4.1 I try a lot of different USB drives before i see some with led on it. And I saw that flashing on start. That drive start to work later then that error message appered. So I try to put there microSD reader with some old micro SD card and voila works like a charm. It looks like there is some bug on 4.4.0 and booting from USB drive with (FAT32,exFAT) Not sure why but that microSD solved my problem. I hope this help to another people cya around

I was able to get my firmware and bootloader to update successfully after I reformatted my USB to FAT32. I had both the Firmware and bootloader update on the flash drive and it updated fairly quickly.

Glad I read this thread!

Did you have to change WPA to WPA2 in the credentials file?
