WIFI network performance dependent on the ESP01S module used.
Hi, i found recently that WIFI performance is dependent a lot from the ESP01s module is used, and that one which is provided with the printer really sucks, on the MINI+ where i had such module, i observer random errors in connection with the printer, and uploads error while the printer was printing (less issues when the printer was in idle). But after i replaced the module for the same i used before (which by accident i put into first printer) i discovered that the new printer is performing much better now... The only difference i spotted is related to flash memory used in that module. I have some ESP01s which i'm using for some stuff, and it was just random pick, for the reference, if you have one of those modules on the left (marked MINI+, and MK4) and having issues with connection on MINI+ and slow general networking on MK4, try to replace with other ESP01s. At least it worked here.
Photo for reference, two modules from the left are part of official supply with printer, on the right some random module i have on the desk, and put into printer to check...:
I have already filed a bug report on github.
Cheers

Maybe worth to check it with a spreadsheet linked in this forum ost https://forum.prusa3d.com/forum/hardware-firmware-and-software-help/prusa-mini-mini-wifi-troubleshooting/paged/3/#post-616793
See my GitHub and printables.com for some 3d stuff that you may like.
