Note : Ensure the USB WiFi is connected to Beaglebone Black/VIBE before device bootup
Instructions
- Check that USB WiFi is visible on the USB bus by:
# lsusb Bus 001 Device 002: ID 0424:2412 Standard Microsystems Corp. Bus 002 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
- Idetify USB WiFi Device listed above supported by Debian
Search your WiFi module is listed on page https://wiki.debian.org/WiFi#USB_Devices
For example,
The WiFi module RTL8188CUS is supported under module name rtl8192cu.
If its not supported, Please contact Yantrr Support team.
- Installing wireless tools and wpasupplicant
# apt-get install wireless-tools
# apt-get install wpasupplicant
- List available wireless interface on system
# iwconfig

lo no wireless extensions.
eth0 no wireless extensions.
- Bring the intended wireless interface up (here its wlan0)
# ip link set wlan0 up
- List names of available access points nearby
# iwlist scan

lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
- Calculate the WPA PSK hash for SSID
# wpa_passphrase ssid_name wifi_password
network={
ssid="myssid"
#psk="my_very_secret_passphrase"
psk=ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b
}
- Add configuration of wlan0 in /etc/network/interfaces, (copy psk value from above step and assign it to wpa-psk)
# nano /etc/network/interfaces
auto wlan0
iface wlan0 inet dhcp
wpa-ssid ssid_name
wpa-psk ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b
- To route all traffic through WiFi connection
# ip route replace default via IP_ADDRESS_OF_WiFi_ROUTER dev wlan0
For example,
# ip route replace default via 192.168.1.1 dev wlan0
- Test your setup
Ping to WiFi router
# ping IP_ADDRESS_OF_WiFi_ROUTER
If getting successful reply, then your wifi connection is configured successfully If getting reply unable to reach destination, down your Ethernet eth0 connection
# ifdown eth0
Again test ping to WiFi router.
