Ive seen several recommendations for changing the channel width of the 2.4 band from Auto to 20mhz but I can find any info on what this actually does.
My questions are: does the 20mhz give better range at the expense of speed? When would you want to select 40mhz instead of 20, or woulddnt "auto" just be better in that I would think it allows the router to determine whats better? Just curious what this setting really does? Thanks.

Thanks. Just so I get it, is there an advantage to selecting either 20mhz or 40mhz rather than setting it to auto? Lets say its an all draft-N environment, is there a loss of speed or range if you set the 2.4 band to auto as oppossed to 40mhz?

Hi, in our company we are using WLAN, all our equipment are Cisco. Our Access point and the wireless adapter are 802.11n. but the Channel Width was set to 20MHz, so the speed shows only half of the max speed of 150MHz. Is it better if we change the channel to 40MHz?
