Sonoff Basic WiFi Wireless Switch NOT SUPPORTING 5 GHZ WIFI Anymore


I bought a couple of Sonoff Basic WiFi Wireless Switches.

Since a while the led blinker and the switches are offline. When trying to re-connect to my wifi network, it says that the 5 ghz network is not supported.

It used to work flawlessly before last month. Can you please let me know what should be done to resolve this issue?

For info, the Sonoff Plug swithes and Led Lamp are still online and working fine.

I thank you in advance.

Best wishes,
