UPDATE:
I was able to update to wifi101 19.5.4 by downloading the Arduino hourly IDE build. Now that I am using 19.5.4 I was able to successfully upload the WiFi101 example sketch to connect to WEP.
However, now I am having the issue that my MKR1000 is not connecting to my SSID. Just keeps trying to connect every 10 seconds.
Any advice?
