What can I do if my wireless USB device does not show up after a reboot?

In some configurations it's possible that a wireless USB device does will show up after a reboot. The typical solution to this problem is to manually unplug the USB adapter and then plug it back in. This normally causes the USB device to reinitialize and show up.

If these cases the following lines can be added to the end of the /etc/rc.local file to automatically restart the adapter whenever the system is rebooted. The eth4 interface should correspond to the actual wireless interface in your system. 

  dldrstop
  /sbin/modprobe driverloader
  /sbin/ifup eth4

This should restart DriverLoader once your system is fully booted and it also generally restarts the wireless USB adapter.
