Increasing this value 182# means sacrificing startup time and gathering more data wrt channel 183# interference that may help choosing a better channel. This can also help fine 184# tune the ACS scan time in case a driver has different scan dwell times. 185# 186# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be 187# used to increase (or decrease) the likelihood of a specific channel to be 188# selected by the ACS algorithm. The total interference factor for each channel 189# gets multiplied by the specified bias value before finding the channel with 190# the lowest value. In other words, values between 0.0 and 1.0 can be used to 191# make a channel more likely to be picked while values larger than 1.0 make the 192# specified channel less likely to be picked. This can be used, e.g., to prefer 193# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default 194# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified). 195# 196# Defaults: 197#acs_num_scans=5 198#acs_chan_bias=1:0.8 6:0.8 11:0.8 199 200# Channel list restriction.
