I found this thread while looking to see if anyone else has recently encountered complete WiFi dropout from their Photons.
In the past I have seen that after being up for a couple of days my photons may lose the ability to connect to WiFi at all. In the past simply resetting the photon by calling System.reset() would fix the immediate problem.
However I now have 2 photons that simply cannot connect to WiFi no matter what I do. What is most odd is that WiFi.macAddress() returns all zeros. If I call WiFi.off() and then WiFi.on() , WiFi.macAddress() will return my proper MAC but if I do it again a few seconds later it will be back to all zeros. Also, it is not as if my WiFi is completely dead. I can scan and find 10 different access points available even though I only have credentials loaded for one.
Note, this is not a single unit. One started doing this and then the other did the same within a few hours. I’ve tried turning off the power for an hour and restarting without making any difference. I was assuming that there had been some firmware update that caused this sudden problem but I’m not seeing a general outcry. I was already having concerns about launching a product with intermittent WiFi issues but this has really put the brakes on. I’ll be watching this thread for updates.
