I thought that it would be easy to connect to a 2.4ghz device but I am having problems. What can I do to allow my BTWHoleHome to provide internet connectivity to smart devices that operate only at 2.4ghz?
You should not need to do anything special. My smart thermostat only operates at 2.4Ghz and it works fine.
I assume you can see the BTWH SSID on the device and it has the correct password.
Can you see it in the devices list ? If not check to see if you can see the MAC address in any of the connected devices as BTWH sometimes incorrectly names devices.
Can you see it in the system logs for one of the discs, try the primary first.
