We have a V2110 HA pair, FW 10.01.06.0006. We're using NAC version 18.104.22.168 for authentication to the wireless network. All other clients can connect fine (phones, laptops, tablets, XBox and Playstation), but Wiis do not work. We get the error code above. This is after the device MAC is added to the authenticated group via the Self-Registration portal.
