Decided to try it with the wired connection. Re powered with the ethernet module connected, got the ip address and entered it into a browser.
Entered the password, click submit and I get a popup asking if I want to save a .json file. Click save and then the submit and I get another popup asking about a different .json file.
This keeps on until I get RSI and give up. The only way to remove the popup is to reboot the computer.
What is happening???
