echo » # In this example it will install the 8192eu wifi module driver. After installing the driver shutdown the «

echo » # and it should start up with the new wifi adapter connected to your network. «

echo » # «

echo » # install-wifi 8192eu — this will install the 8192eu module for the current kernel «

echo » # if you want to run rpi-update, first check a driver is available before you update your code. If the check «

echo » # «

echo » # install-wifi -c rpi-update — check for driver if rpi-update is run. «

echo » # «

echo » # install-wifi -c 8812au rpi-update — check for 8812au driver if rpi-update is run. «

echo » # sudo rpi-update — if a driver is available you can run rpi-update to update firmware. «

echo » # install-wifi -u 8812au rpi-update — install the 8812au driver for the new kernel installed by rpi-update. «

echo » # sudo halt — shutdown the Pi, replace the wifi adapter with the 8812au wifi adapter. «
