I’ve bought two smart sockets and neither will connect to my broadband - I’ve connected them via personal hotspot and they work fine, so it’s an issue with my WiFi rather than the sockets themselves.
The instructions for the sockets (made by Teckin) suggest they only work on 2.4G broadband - I have a Hub 3.0 which I understand is dual band, so might this be causing the issue? They also suggest checking if the routers wireless MAC filtering functions are enabled, which I have no idea about!
The socket manufacturer also sent the following over email when corresponding on this issue: “Be sure that you are using 2.4GHz WiFi when connect with smart plug. And WiFi must be detectable status. In addition, the router encryption mode must be WPA2-PSK type and the authentication type must be AES.” I have no idea how to correct these things so any help on what to do with my router to make these sockets usable would be hugely appreciated!
