Setting up WiFi Access on Router
The following instructions assume a Debian derivative Linux distro.
#!bash # Install required packages # ------------------------- sudo apt-get -qq -y install hostapd dnsmasq # Bring up driver for the local wifi adaptor # ------------------------------------------ # If the wifi interface is not up already, you can use tools such as 'lspci' # or 'lsusb' to find which wifi adaptor is installed and load the appropriate # driver. E.g., for all Atheros IEEE 802.11n PCI/PCI-Express and AHB WLAN based # chipsets use the 'ath9k' driver. sudo modprobe ath9k # To determine which interface came up from above driver action, check using sudo ifconfig -a # Note: if your node uses NetworkManager to manage an active Internet connection # (e.g., if you are using a laptop to run as an access router), you may have to # disable this daemon first and activate the device if blocked: sudo nmcli nm wifi off sudo rfkill unblock wlan # Configure interface # ------------------- # bring up WiFi interface with IP and netmask. This will be the AP's IP. sudo ifconfig wlan0 192.168.1.1 netmask 255.255.255.0 up # Set up DHCP (optional) # ---------------------- # Edit DHCP configuration in /etc/dnsmasq.conf to alter interface, IP range, # and to add any particular MAC-IP assignment bindings to be enforced # See sample configuration in section below. sudo vi /etc/dnsmasq.conf # restart DHCP service: sudo service dnsmasq restart # Configure and Bringup hostapd # ----------------------------- # Create/edit a hostapd.conf (sample shown below) to configure interface, essid, # channel, passphrase etc., for the AP. Using '/etc/hostapd/hostapd.conf' as # the location makes it convenient for automation sudo vi /etc/hostapd/hostapd.conf # To automate initialization, edit '/etc/default/hostapd' to uncomment and set # DAEMON_CONF to the absolute path of your hostapd configuration file. This also # enables hostapd to be started at boot. sudo vi /etc/default/hostapd #DAEMON_CONF="/etc/hostapd/hostapd.conf" # To start, stop, restart hostapd: sudo /etc/init.d/hostapd {start|stop|restart} # or use 'service' tool sudo service hostapd {start|stop|restart} # Here's the manual way to bring up hostapd if needed (-B sets background mode): sudo hostapd -BtKd /etc/hostapd/hostapd.conf
Sample hostapd Configuration
#!bash interface=wlan0 driver=nl80211 ssid=mfaccess-test # hw_mode: always a subset of a, b, g hw_mode=g channel=11 macaddr_acl=0 auth_algs=1 ignore_broadcast_ssid=0 # wpa=3 enables wpa & wpa2 wpa=3 wpa_passphrase=mfaccess-test wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP
Refer to the hostapd documentation for further details.
Sample Dnsmasq Configuration
#!bash interface=wlan0 # dhcp-range=<startIP>, <endIP>,<lease time> dhcp-range=192.168.1.128,192.168.1.254,24h dhcp-host=aa:22:bb:44:cc:66,192.168.1.128
Bringing up Access Router
Now that the wireless interface is setup for clients to connect and authenticate, bring up MobilityFirst access router as show in router configurations page
