Here's how the Smart Connect works. This feature is not suitable for every environment or individual case.

For example: I am not using it, since I want to have two separate wireless SSIDs for different type of devices:

2.4 GHz for smart home devices, cameras, etc. and 5GHz for bandwidth demanding devices.

However 'Auto' for selecting the least congested wireless channel on a particular wireless band is another feature.

If 'Auto' doesn't work as expected in your case, you could use an apps like Wi-Fi Analyzer or inSSIDer to scan for a less congested channels on the particular wireless band and select them manually.
