150# ACS tuning - Automatic Channel Selection
151# See: http://wireless.kernel.org/en/users/Documentation/acs
152#
153# You can customize the ACS survey algorithm with following variables:
154#
155# acs_num_scans requirement is 1..100 - number of scans to be performed that
156# are used to trigger survey data gathering of an underlying device driver.
157# Scans are passive and typically take a little over 100ms (depending on the
158# driver) on each available channel for given hw_mode. Increasing this value
159# means sacrificing startup time and gathering more data wrt channel
160# interference that may help choosing a better channel. This can also help fine
161# tune the ACS scan time in case a driver has different scan dwell times.
162#
163# acs_chan_bias is a space-separated list of <channel>:<bias> pairs. It can be
164# used to increase (or decrease) the likelihood of a specific channel to be
165# selected by the ACS algorithm. The total interference factor for each channel
166# gets multiplied by the specified bias value before finding the channel with
167# the lowest value. In other words, values between 0.0 and 1.0 can be used to
168# make a channel more likely to be picked while values larger than 1.0 make the
169# specified channel less likely to be picked. This can be used, e.g., to prefer
170# the commonly used 2.4 GHz band channels 1, 6, and 11 (which is the default
171# behavior on 2.4 GHz band if no acs_chan_bias parameter is specified).

2099##### Multiple BSSID support ##################################################
2100#
2101# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
2102# interfaces). Other BSSIDs can be added by using separator 'bss' with
2103# default interface name to be allocated for the data packets of the new BSS.
2104#
2105# hostapd will generate BSSID mask based on the BSSIDs that are
2106# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
2107# not the case, the MAC address of the radio must be changed before starting
2108# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
2109# every secondary BSS, this limitation is not applied at hostapd and other
2110# masks may be used if the driver supports them (e.g., swap the locally
2111# administered bit)
2112#
2113# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
2114# specified using the 'bssid' parameter.
2115# If an explicit BSSID is specified, it must be chosen such that it:
2116# - results in a valid MASK that covers it and the dev_addr
2117# - is not the same as the MAC address of the radio
2118# - is not the same as any other explicitly specified BSSID
2119#
2120# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
2121# hostapd to use the driver auto-generated interface address (e.g., to use the
2122# exact MAC addresses allocated to the device).
2123#
2124# Not all drivers support multiple BSSes. The exact mechanism for determining
2125# the driver capabilities is driver specific. With the current (i.e., a recent
2126# kernel) drivers using nl80211, this information can be checked with "iw list"
2127# (search for "valid interface combinations").
2128#
2129# Please note that hostapd uses some of the values configured for the first BSS
2130# as the defaults for the following BSSes. However, it is recommended that all
2131# BSSes include explicit configuration of all relevant configuration items.
2132#
