I had a MKR1000 that has been connected to WiFi Since past 1 week. yesterday on 10th January, 2018 at 5:00 p.m. its connection got interrupted and ever since its unable to connect to WiFi.
On repeated attempts to connect it to WiFi, its returning the WL_CONNECT_FAILED output.
What are possible reasons for connection failed and how can I overcome this problem and find a permanent solution without resetting the MKR1000.
As resetting the MKR1000 causes all the data stored to be lost which has not been transferred to server.
As for why it has not re-connected it is a little hard to say.
Useful things would be a copy of the sketch and knowing if you have the latest firmware.
