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).
_____ ___________
| | eth0 | | wlan0(AccessPoint 2.5G)
|box|-----< Eth USB1>WLAN0_Stick <<<<<< Smartphone
|___| | Debian |
| Device | wlan1(AccessPoint 5G)
| USB2>WLAN1_Stick <<<<<< PC/Laptop
|___________|
My initial config (hostapd & dnsmasq) for single wlan0 (AccessPoint 2.5G)
/etc/hostapd.conf
# 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
/etc/dnsmasq.conf
# 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
In order to initialize AP1 I use following bash-script
start.sh
!/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 /etc/hostapd_5G.conf
for wlan1
similar as /etc/hostapd.conf
& changed dnsmasq.conf
& 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).

I think you will need to bridge the
wlan0
andwlan1
somehow. You can see OpenWRT does that. Have a look atbridge-utils
package.Adding this to /etc/network/interfaces may help:
