Stuck on WiFi #help #morserino


I have the new v.4.1 and finally got to work with WiFi although slow.
After a few days,  now of can't connect to WiFi and can't get it off the WiFi mode.
It's stuck on "Transverter WiFi" looking to connect.
How do I reset so I can use the other functions like CW and Echo, etc.
Holding or dou9ble clicking the black knob doesn't do anything.
Same with red button and of course turning the power on and off..
Please advice.
