Hi,
A few ago our campany (I'm an intern! 
) bought an Arduino Uno WIFI (Developer Edition), and it certainly seemed to work well. It will broadcast an unsecured WIFI-connection, which can be used to change settings for WIFI and MQTT-protocol. Since last week, it is very difficult to establish a WIFI-connection, and the connection is too unstable to make any changes.
The actions I have taken:
- Set up a test in an environment with no / Weining WiFi networks;
- Upload a blank sketch;
- Press the reset button.
Is this a common known problem?
