USB WiFi dongles

Most all below BASH commands needs to be executed as user 'root'.
Best practice if troubleshooting/installing WiFi is to login via SSH using the wired interface 'eth0'.

When your WiFi dongle is detected and drivers are loaded properly, easiest way to change WiFi settings is using:


To check WiFi status:


If your WiFi dongle is designated as 'wlan1' and you want to change to 'wlan0', if not conflicting with other interfaces, you can alter in below file if exists:

nano /etc/udev/rules.d/70-persistent-net.rules

Sometimes the WiFi connection cant be established quick enough on boot and you run into troubles if using a shared MySQL database for Kodi/XBMC.
To delay Kodi/XBMC at boot (asuming WiFi is on 'wlan0' interface):

sed -i "s/start on started mountall/start on started mountall and started networking and net-device-up wlan0/" /etc/init/xbmc-preload.conf

List 'wlan0' driver specific parameters:

grep '' /sys/module/$(readlink /sys/class/net/wlan0/device/driver/module | xargs -n 1 basename)/parameters/*

To determine vendor/device id for connected USB devices:


Vendor/device id “0bda:8179”
Driver is already installed at ”/lib/modules/$(uname -r)/kernel/drivers/staging/rtl8188eu/r8188eu.ko”.
But needs below firmware blob:

mkdir /lib/firmware/rtlwifi
wget -O /lib/firmware/rtlwifi/rtl8188eufw.bin
echo "options r8188eu rtw_power_mgnt=0 rtw_enusbss=0" > /etc/modprobe.d/r8188eu.conf

Vendor/device id “0df6:0077”
Firmware blob is already installed at ”/lib/firmware/rtlwifi/rtl8192cufw.bin”.
But needs a driver assigned thats already installed:

echo 'install 8192cu /sbin/modprobe --ignore-install 8192cu; /bin/echo "0df6 0077" >| /sys/bus/usb/drivers/rtl8192cu/new_id' | tee /etc/modprobe.d/8192cu.conf
echo "options 8192cu rtw_power_mgnt=0 rtw_enusbss=0" >> /etc/modprobe.d/8192cu.conf
echo "8192cu" >> /etc/modules
