RBS-40 Non-Working Piece of Junk

Purchased a two unit RBR-50 and RBS-50 set that has worked fine. However - the RBS-40 that was purchased at the same time has never been able to connect. When it is plugged in Wi-Fi is blocked on all devices. Wired connectivity through the RBR-50 still works.

If you look in the RBS-50 console you can see it - but no Address or Firmware info.

RBR-50 and RBS-50 are running V2.1.1.16 - I keep upgrading hoping that this piece of junk will finally connect. Of course I didn't have time to sit on the phone with "support" in the first 90 days so now they tell me I'm pretty much out of luck.

Have done all the resync processes - factory reboot evenything I can find on the forums with no luck. Thought I might be able to connect to the SSID on the lable on the bottom directly and upgrade the firmware that way. 

Is it possibly to direct connect to the unit to update the firmware? Is there any other steps I can try to salvage this purchase? It's an expensive paperweight.
