Hi, the 2.4ghz frequency is no longer working on my superhub 3. I can see the connection but it comes and goes with zero signal strength showing. 5ghz is working fine but I have done old devices that need 2.4ghz.
I have tried rebooting the hub multiple times, turning the frequency off and on again, turned off the guest mode and smart setting. Tried different channels, changing password and WiFi connection name so it doesn't match 5ghz in any way. Tried 20 and 40 MHz, still no joy.
