167# ACS tuning - Automatic Channel Selection
168# See: http://wireless.kernel.org/en/users/Documentation/acs
169#
170# You can customize the ACS survey algorithm with following variables:
171#
172# acs_num_scans requirement is 1..100 - number of scans to be performed that
173# are used to trigger survey data gathering of an underlying device driver.
174# Scans are passive and typically take a little over 100ms (depending on the
175# driver) on each available channel for given hw_mode. Increasing this value
176# means sacrificing startup time and gathering more data wrt channel
177# interference that may help choosing a better channel. This can also help fine
178# tune the ACS scan time in case a driver has different scan dwell times.
179#

180# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
181# used to increase (or decrease) the likelihood of a specific channel to be
182# selected by the ACS algorithm. The total interference factor for each channel
183# gets multiplied by the specified bias value before finding the channel with
184# the lowest value. In other words, values between 0.0 and 1.0 can be used to
185# make a channel more likely to be picked while values larger than 1.0 make the
186# specified channel less likely to be picked. This can be used, e.g., to prefer
187# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
188# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

1660# WPS capability discovery workaround for PBC with Windows 7
1661# Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting
1662# as a Registrar and using M1 from the AP. The config methods attribute in that
1663# message is supposed to indicate only the configuration method supported by
1664# the AP in Enrollee role, i.e., to add an external Registrar. For that case,
1665# PBC shall not be used and as such, the PushButton config method is removed
1666# from M1 by default. If pbc_in_m1=1 is included in the configuration file,
1667# the PushButton config method is left in M1 (if included in config_methods
1668# parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label

2168##### Multiple BSSID support ##################################################
2169#
2170# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
2171# interfaces). Other BSSIDs can be added by using separator 'bss' with
2172# default interface name to be allocated for the data packets of the new BSS.
2173#
2174# hostapd will generate BSSID mask based on the BSSIDs that are
2175# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
2176# not the case, the MAC address of the radio must be changed before starting
90ac1f9f
JM
2177# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
2178# every secondary BSS, this limitation is not applied at hostapd and other
2179# masks may be used if the driver supports them (e.g., swap the locally
2180# administered bit)
6fc6879b
JM
2181#
2182# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
2183# specified using the 'bssid' parameter.
2184# If an explicit BSSID is specified, it must be chosen such that it:
2185# - results in a valid MASK that covers it and the dev_addr
2186# - is not the same as the MAC address of the radio
2187# - is not the same as any other explicitly specified BSSID
2188#
6448e064
EP
2189# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
2190# hostapd to use the driver auto-generated interface address (e.g., to use the
2191# exact MAC addresses allocated to the device).
2192#
978c6730
JM
2193# Not all drivers support multiple BSSes. The exact mechanism for determining
2194# the driver capabilities is driver specific. With the current (i.e., a recent
2195# kernel) drivers using nl80211, this information can be checked with "iw list"
2196# (search for "valid interface combinations").

2198# Please note that hostapd uses some of the values configured for the first BSS
