166# ACS tuning - Automatic Channel Selection
167# See: http://wireless.kernel.org/en/users/Documentation/acs
168#
169# You can customize the ACS survey algorithm with following variables:
170#
171# acs_num_scans requirement is 1..100 - number of scans to be performed that
172# are used to trigger survey data gathering of an underlying device driver.
173# Scans are passive and typically take a little over 100ms (depending on the
174# driver) on each available channel for given hw_mode. Increasing this value
175# means sacrificing startup time and gathering more data wrt channel
176# interference that may help choosing a better channel. This can also help fine
177# tune the ACS scan time in case a driver has different scan dwell times.
178#
68fa00c3
JM
179# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
180# used to increase (or decrease) the likelihood of a specific channel to be
181# selected by the ACS algorithm. The total interference factor for each channel
182# gets multiplied by the specified bias value before finding the channel with
183# the lowest value. In other words, values between 0.0 and 1.0 can be used to
184# make a channel more likely to be picked while values larger than 1.0 make the
185# specified channel less likely to be picked. This can be used, e.g., to prefer
186# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
187# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

2045# WPS capability discovery workaround for PBC with Windows 7
2046# Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting

2049# the AP in Enrollee role, i.e., to add an external Registrar. For that case,
2050# PBC shall not be used and as such, the PushButton config method is removed
2051# from M1 by default. If pbc_in_m1=1 is included in the configuration file,
2052# the PushButton config method is left in M1 (if included in config_methods
