Note: Following instructions have only be tested on APF6 and OPOS6UL/OPOS6UL_NANO |
Installation
- You will need hostapd (installed by default on APF6 & OPOS6UL/OPOS6UL_NANO). If not installed:
$ make menuconfig
Target packages --->
Networking applications --->
[*] hostapd
[ ] Enable EAP
[ ] Enable WPS
- then, reflash your rootfs or rsync it, if your board has SSH access through Ethernet port.
Configuration
- Bring up your Wi-Fi interface and give it an address (here 192.168.2.1):
# ifconfig wlan0 up 192.168.2.1 netmask 255.255.255.0
- Create /etc/hostapd/ directory and put it this hostapd.conf configuration file:
# mkdir -p /etc/hostapd/ # cat > /etc/hostapd/hostapd.conf <<EOF interface=wlan0 ctrl_interface=/var/run/hostapd ssid=OPOSSOM hw_mode=g channel=6 #auth_algs=1 wpa=2 wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP wpa_passphrase=YOUHOULESBILOUS EOF
- here we used fixed channel (6) (as some drivers can't allow hostapd to find less occupied channel through scanning)
- security is WPA2-PSK. To have "Open" Access Point uncomment #auth_algs=1 and comment 3 wpa lines
- Launch hostapd:
# hostapd -B /etc/hostapd/hostapd.conf
- If the devices connecting to your Access Point require dynamic IP address allocation, you will need to install a DHCP server on your APF/OPOS too.
AP+STA mode
- It is also possible to configure your module to act as a Wi-Fi client/station (STA), and in the same time offer AP (Access Point) services.
- For this you have to create virtual network interface (here uap0) and use it instead of wlan0 for AP stuff configuration (hostapd and dnsmasq):
# iw dev wlan0 interface add uap0 type __ap # ifconfig uap0 192.168.10.1
- So after this you have:
- a Wi-Fi interface wlan0 for station(STA)/client mode usable with for example WPA supplicant
- and a Wi-Fi interface uap0 for access point(AP) mode, usable with previous instructions on this page.
Control
- When launched, you can control hostapd daemon with corresponding command line tool:
# hostapd_cli
