173# ACS tuning - Automatic Channel Selection
174# See: https://wireless.wiki.kernel.org/en/users/documentation/acs
175#
176# You can customize the ACS survey algorithm with following variables:
177#
178# acs_num_scans requirement is 1..100 - number of scans to be performed that
179# are used to trigger survey data gathering of an underlying device driver.
180# Scans are passive and typically take a little over 100ms (depending on the
181# driver) on each available channel for given hw_mode. 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).

2103#
2104# Each sae_password entry is added to a list of available passwords. This
2105# corresponds to the dot11RSNAConfigPasswordValueEntry. sae_password value
2106# starts with the password (dot11RSNAConfigPasswordCredential). That value can

2658# WPS capability discovery workaround for PBC with Windows 7
2659# Windows 7 uses incorrect way of figuring out AP's WPS capabilities by acting
2660# as a Registrar and using M1 from the AP. The config methods attribute in that
2661# message is supposed to indicate only the configuration method supported by
2662# the AP in Enrollee role, i.e., to add an external Registrar. For that case,
2663# PBC shall not be used and as such, the PushButton config method is removed
2664# from M1 by default. If pbc_in_m1=1 is included in the configuration file,
2665# the PushButton config method is left in M1 (if included in config_methods
2666# parameter) to allow Windows 7 to use PBC instead of PIN (e.g., from a label

3360##### Multiple BSSID support ##################################################
3361#
3362# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
3363# interfaces). Other BSSIDs can be added by using separator 'bss' with
3364# default interface name to be allocated for the data packets of the new BSS.
3365#
3366# hostapd will generate BSSID mask based on the BSSIDs that are
3367# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
3368# not the case, the MAC address of the radio must be changed before starting
3369# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
3370# every secondary BSS, this limitation is not applied at hostapd and other
3371# masks may be used if the driver supports them (e.g., swap the locally
3372# administered bit)
3373#
3374# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
3375# specified using the 'bssid' parameter.
3376# If an explicit BSSID is specified, it must be chosen such that it:
3377# - results in a valid MASK that covers it and the dev_addr
3378# - is not the same as the MAC address of the radio
3379# - is not the same as any other explicitly specified BSSID
3380#
3381# Alternatively, the 'use_driver_iface_addr' parameter can be used to request
3382# hostapd to use the driver auto-generated interface address (e.g., to use the
3383# exact MAC addresses allocated to the device).
3384#
3385# Not all drivers support multiple BSSes. The exact mechanism for determining
3386# the driver capabilities is driver specific. With the current (i.e., a recent
3387# kernel) drivers using nl80211, this information can be checked with "iw list"
3388# (search for "valid interface combinations").
3389#
3390# Please note that hostapd uses some of the values configured for the first BSS
3391# as the defaults for the following BSSes. However, it is recommended that all
3392# BSSes include explicit configuration of all relevant configuration items.

3403# Multiple BSSID Advertisement in IEEE 802.11ax
3404# IEEE Std 802.11ax-2021 added a feature where instead of multiple interfaces
3405# on a common radio transmitting individual Beacon frames, those interfaces can
3406# form a set with a common Beacon frame transmitted for all. The interface
3407# which is brought up first is called the transmitting profile of the MBSSID
3408# set which transmits the Beacon frames. The remaining interfaces are called
3409# the non-transmitting profiles and these are advertised inside the Multiple
3410# BSSID element in the Beacon and Probe Response frames from the first
3411# interface.
3412#
3413# The transmitting interface is visible to all stations in the vicinity, however
3414# the stations that do not support parsing of the Multiple BSSID element will
3415# not be able to connect to the non-transmitting interfaces.
3416#
3417# Enhanced Multiple BSSID Advertisements (EMA)
3418# When enabled, the non-transmitting interfaces are split into multiple
3419# Beacon frames. The number of Beacon frames required to cover all the
3420# non-transmitting profiles is called the profile periodicity.
3421#
3422# Refer to IEEE Std 802.11-2020 for details regarding the procedure and
3423# required MAC address assignment.
3424#
