Automatic Reconnect after Reset
After a reset (like when saving config.g) DWC should automatically reconnect to the control board similar to the one wehn doing an emergency stop.
It already does on my printers. Which version of DWC are you using?
I am using DWC v1.20 with Firefox
I have just tried the same on mine and after a rest boot post Config.g upload mine also stays disconnected
Currently on 1.21RC1 for FW and WiFi Server and 1.20 for DWC.
