I am trying to set up 2 wireless access points from linux device (Debian Jessy). Both AP's should work simultaneously & share Internet connection (as shown below).
My initial config (hostapd & dnsmasq) for single wlan0 (AccessPoint 2.5G)
_____ ___________ | | eth0 | | wlan0(AccessPoint 2.5G) |box|-----< Eth USB1>WLAN0_Stick <<<<<< Smartphone |___| | Debian | | Device | wlan1(AccessPoint 5G) | USB2>WLAN1_Stick <<<<<< PC/Laptop |___________|
# Define interface interface=wlan0 # Select driver driver=nl80211 # Set access point name ssid=AP-wifi-2G # Set access point harware mode to 802.11g hw_mode=g # Set WIFI channel (can be easily changed) channel=6 # Enable WPA2 only (1 for WPA, 2 for WPA2, 3 for WPA + WPA2) wpa=2 wpa_passphrase=wifi123456
In order to initialize AP1 I use following bash-script
# Bind to only one interface bind-interfaces # Choose interface for binding interface=wlan0 # Specify range of IP addresses for DHCP leasses dhcp-range=192.168.150.2,192.168.150.10
!/bin/bash # Start # Configure IP address for WLAN sudo ifconfig wlan0 192.168.150.1 # Start DHCP/DNS server sudo service dnsmasq restart # Enable routing sudo sysctl net.ipv4.ip_forward=1 # Enable NAT sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # Run access point daemon sudo hostapd /etc/hostapd.conf # Stop # Disable NAT sudo iptables -D POSTROUTING -t nat -o eth0 -j MASQUERADE # Disable routing sudo sysctl net.ipv4.ip_forward=0 # Disable DHCP/DNS server sudo service dnsmasq stop
This config works fine for single AP (
wlan0, AccessPoint 2.5G)
I added the 2nd config
wlan1 similar as
/etc/hostapd.conf & changed
start.sh (wlan0->wlan1 for testing) - it also worked good in 5G.
But I need to run wlan0 AP & wlan1 AP simultaneously. I think I need to modify
dnsmasq.conf for second interface. But I don't know how to do this.
Anyone please help with simultaneous configuration (wlan0 AP & wlan1 AP).
