    Lightbulb Archer C9 won't connect with Sonoff TH WiFi switches?

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    HiI've just replaced my router with a tp-link Archer C9. However I can't get any of my 3 Sonoff TH units to connect with it. I have tried various security settings including no security and no password. I've made sure the mobile I'm using to add the sonoff is connected to the 2.4 band and not the 5ghz band. I have also dropped the bandwidth from 40mhz to 20mhz but they still won't connect. My other 10 devices seem to connect fine to 2.4ghz including cameras laptops and TV boxes. I've also tried different security types and made sure the firmware is the latest. I think the clue is that the router supports up to 600mbps not 300mbps like most routers. Even though I've dropped the bandwidth to 20mhz my phone still says it's connected at 192mbps. My old modem used to show 130mbps. I think this is the problem. Would anyone have any suggestions as to how to get these three units to connect please

    i think you can ask sonoff TH unit company what setting can change on the router to make it connect. As your other devices can connect fine.
