Well, after reading the /usr/share/acpi-support/screenblank file you 
said, the only line being run there was "xset dpms force off". I ran 
that in the terminal hoping it would disrupt my wireless connection to 
no avail.

I came to figure out that - for some weird reason I cannot explain nor 
will I try to - the fact that I was calling the command through a key 
combination altogether with the keys I used to call it, were causing the 
problem. For the record, the key combination was 
<Control><Alt>XF86MonBrightnessDown and the command ultimately was "xset 
dpms force off".
I came about a fix simply by changing the key combination to 
<Control><Alt>B.

Title:
  screenblank.sh script shuts down disrupts wireless connection

Status in “acpi-support” package in Ubuntu:
  Incomplete

Bug description:
  I have noticed that running the screenblank.sh script (at
  /etc/acpi/screenblank.sh) disrupts the wireless connection. The
  connection is cut off and the wireless device can no longer
  successfully scan for wireless connections until after its switched
  off and on again.

  Please tell me how I can help solving this problem.
