I have here a wemos board that was running WLED (8 ws2812 LEDs) with version 0.9 for long time. Today I tried to update it via OTA. Doesn’t worked, so I flashed it manually via the install-page. After that, it didn’t found any more the wifi-network. Then i flashed back via espflasher to 0.9 again, same result, it did not connect.
So I tried other firmwares like tasmota and espeasy. Old versions of tasmota worked, same to espeasy. A new version of luciferin works, too. I unpacked a new wemos-board (I have a bunch here since some years) and unfortunately, same result.
Now I am totally confused why this does not connect any more to my wlan.
Did you look in your available wifi networks for WLED-AP? If you reflashed the board you will need to reconnect it to your wifi SSID/PW.

Yes, when configuring the wifi in the next step, it finds nothing. Not even the open wifi nearby or the hotspot from my mobile 40cm away. Very strange.
I expected that it opens the wled-wifi, but there is nothing. Unfortunately, there is no debug message on the serial console.
I flashed tonight one of those really simple esp8266-modules (ESP-12F) and it was immediatly running. So, it seems some kind of aging seems to be happend to those wemos modules. But what?
