I have a Wemos D1 Mini running an example script, HelloServer.ino. It did work yesterday, but today I cannot get the Wemos to connect to the AP. The WL_STATUS is "WL_NO_SSID_AVAIL".
It worked yesterday, and nothing has changed but for a boards upgrade on the Arduino IDE.
Now for the really puzzling part. I can flash Tasmota on the Wemos and it connects just fine. Same SSID, same password. I can open the Tasmota IP on the Wemos and the WiFi server works just fine.
Also, I've tried other example sketches that connect to WiFi and none of them work. Yet, the same exact code works on a nodeMCU?
To summarize: The sketch worked yesterday, but not today. I changed nothing in the sketch and the sketch runs fine in a NodeMCU. I have used three different Wemos D1 Mini's and a NodeMCU for my testing. Other sketches that don't need WiFi run just fine on the Wemos.
I am running out of ideas - any help would be appreciated.
