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.

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.

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# 2133#bss=wlan0_0 2134#ssid=test2 2135# most of the above items can be used here (apart from radio interface specific 2136# items, like channel) 2137 2138#bss=wlan0_1 2139#bssid=00:13:10:95:fe:0b 2140# ... 2141
