-Issues getting wireless working.  First thought was that the integrated Bluetooth device was having some kind of hardware conflict with the wireless card.  Running <code>rfkill list</code> showed the wireless card subject to a hardware block, which usually stems from a wireless switch.  However, flipping the wireless switch (physical switch immediately below the center of the palm rest, SoftKey = Fn+F2) would bring the bluetooth up and then down, but leave the wireless as it was.  Turns out, the solution was a BIOS option.
