Can't connect to Duet board: Network scan failed

[tylersuard]

Can't connect to DWC. When I first bought my Duet, everything worked fine. After a few months, I noticed that I had to connect to the board with a USB cable and turn the network connection off and on again (M552 S-1 and then M552 S1) a few times before it would connect to my internet, but I figured that was just an annoyance I can put up with. Now, today, my trick of turning the network connection off and on again is not working, and I am getting this:

WiFi module is idle
Error: WiFi module reported: network scan failed
WiFi module is idle
Error: WiFi module reported: network scan failed
WiFi module is idle

Repeated thousands of times, and then:
WiFi module is connected to access point , IP address 255.255.255.255

Which of course does not work.
