how wide is each wifi channel
Range is not an issue for me. I am more interested in the ideal setting for higher quality wifi calls. b) Auto (20 MHz or 40 MHz). Each 'band' or channel on the WiFi 2.4GHz is 5Mhz ... channel 6 for example uses 20HMz and there is a guard band or gap between that and the outside of challel 11. Setting 40Mhz gives 'you' mor bandwidth, and opens you up for more interference from/to others.
