Looking at the firmware page, there appears to be a new version of GXW42xx released.
“v2” units use (as of this writing) version 1.0.3.4 firmware and are not the same as the “v1” hardware units, in that they will have “v2” printed on the label, along with a random admin password to make the devices more secure by default than the “v1” units.
However, there are no release notes available for the “v2” firmware… On top of that, there is some confusion as to how the user-agent string presents itself to a provisioning server so that a server can properly decide if the device is v1 or v2, since prior to this “v2” appearance, our user agent strings from “v1” devices have actually shown major hardware versions from 1 through 3 anyhow.
