v2 of Cole's wlan support

* Incorporated Jim's feedback (v1 & v2)

* Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.

* Made comment more detailed about the wired case to explain better
  how it differentiates between wired network interfaces and USB
  devices.
