Overview

There are likely many different boards used within these things and chipsets may potentially vary. A good number (.. including this one) may possibly be counterfeit / fake.

The one shown in this entry would seem to be from whatever group made / sold the Wifly-City stuff

The label states the CoO as Taiwan.. but that may be questionable for some.

The URL on the adapter is http://www.gsky-link.com/. It's long since perma-down, but it's still available via archive.org.
