hi
one of the printers, in the house is running with beta 3
but sometimes im loosing connection to the web interface. Wifi led is on. and i can find the server ip on the router, The issue is gone after restarting the board, but sometimes it shows up again..
i did try to ping the server and no error even without connection to web interface.
i notice when one computer is on the webinterface. and i go in from the mobile, Then the web interface refreshes on the computer.
some info
2.4 ghz wifi
Channel 1.
WPA2
Duet2wifi:
running with beta 3
DuetWiFiModule_32S3.bin
i can´t send the M122 log yet, as the printer is running, and i cant connect to it yet. 
Best regards from me
