I found this method of reconnecting the WIFI dongle from this post. But, I want to be clear on how it works, before I try and implement it.

  1. Go to /etc/ifplugd/action.d/ and rename the ifupdown file to ifupdown.original.
  2. Then do: cp /etc/wpa_supplicant/ifupdown.sh ./ifupdown.
  3. Finally: sudo reboot
  1. When is /etc/ifplugd/action.d/ifupdown called ?
  2. What does the script /etc/wpa_supplicant/ifupdown.sh essentially do in laymens terms, it looks pretty complex to me; and when is it called too.
  3. Could doing steps 1 to 3 cause any other unforeseen problems that would prevent my WIFI from working? I'm trying to implement this on a Raspberry PI, via SSH, without a keyboard and monitor in a hard to reach location.

I tried to Google various bits, but got a bit lost!
