My experience with a Behringer x18 mixer - which is a single channel 2.4g band device - is that if you pick a clear channel it can maintain the connection quite reliably but in a noisy environment became very hit and miss.

Now use an external dual band router and connect using the 5g band, many more usable channels and so very easy too get a clean signal.

On 2.4 gig you can really only use 1, 6 and 11 due to the bandwidth of the signals.

I use a Wi-Fi sniffer app to check channel usage at a venue and then change band if necessary. Never had to switch my 5G channel.

In a public environment I'd recommend an external router than does 5g and connect using that.
