+# You can customize the ACS survey algorithm with following variables:
+#
+# acs_num_scans requirement is 1..100 - number of scans to be performed that
+# are used to trigger survey data gathering of an underlying device driver.
+# Scans are passive and typically take a little over 100ms (depending on the
+# driver) on each available channel for given hw_mode. Increasing this value
+# means sacrificing startup time and gathering more data wrt channel
+# interference that may help choosing a better channel. This can also help fine
+# tune the ACS scan time in case a driver has different scan dwell times.
+#
+# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
+# used to increase (or decrease) the likelihood of a specific channel to be
+# selected by the ACS algorithm. The total interference factor for each channel
+# gets multiplied by the specified bias value before finding the channel with
+# the lowest value. In other words, values between 0.0 and 1.0 can be used to
+# make a channel more likely to be picked while values larger than 1.0 make the
+# specified channel less likely to be picked. This can be used, e.g., to prefer
