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.

  • 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.
