for 2.4gzh if you have no overlap from other AP,s or SSID then in the App click on the 3 dots to the top Radio Managment
change the 2.4 Ghz radio from 20mhz to 20/40mhz this will increase the bandwith if the clinet support 40mhz
The downside to using 40 MHZ wide channels in the 2.4 GHZ band is that you will only have one non overlapping channel. When using 20 MHZ channels you have three non overlapping channels. If you switch to 40 MHZ wide channels,
On 5 GHz, that's a different kettle of fish - there's enough spectrum/non-overlapping channels to support it.eben aht higher channel bonds
