 BPI Stability Issues: 
BPI WiFi seems highly susceptible to interference, so much so that it is not functioning in rack or lab setups, necessitating the use of WiFi chamber for testing.
In open lab environment, BPI stops broadcasting all WiFi SSIDs and the WiFi functionality will not be restored even on reboot or factory reset.
The fan unit is not functioning when connected as per BananaPi’s official documentation, resulting in overheating of the devices.
WiFi 6GHz is not working

1. Depending on your setup environment, you may face interference issues (e.g. in a lab with a lot of WiFi devices). If you encounter such issues we recommend to use a WiFi chamber. A simple desktop setup should not encounter such issues.
2. The Fan unit needs to be setup correctly to avoid overheating.  After connecting the powersupply (white jack) to the fan ensure the jack makes proper contact with the pin, see RDK-B Banana Pi R4 Setup and Flashing Instructions.
3. WiFi 6GHz does not work with all 6GHz capable STAs/clients, we recommend to use an Apple iphone-16 pro as of now if you wish to use Wifi 6GHz.
