Al ESP8266 lost wifi

1

Hi all,

Recently i lost WiFi-connection via the router to all ESP8266 devices. Suddenly the internet slowed down at our house. After that all flashed Sonoff’s en Shelly’s became unavailble in Home Assistant at the same moment.
When i logging in to our router only our smartphones and google home-devices stayed connected. Our Ecovacs (robotvacuum) also lost connection. I can acces these now dead sonoff via the 40 seconds reset button on de sonoff’s and establishing al wifi connection with the device. But after reentering our wifi ssid en pasword i cant find these devices in my router. Has anyone an idea what might have been happend?

sounds like your router took a crap, my d-link did that once, where the 2.4GHz radio died but the 5GHz still worked, I use a separate router and access point now because transferring all the remote routing and port forwarding rules to the new device sucked
