Well, again, this is outside of my comfort zone, but was the router able to find the wireless adapter?
You have an ethernet cable going from the AC3 to the adapter, right? Are the orange and green lights on around the AC3's port?
Perhaps you have the router firewalled, and need to give it permission. Like I do with my laptops. I get the item's MAC adress, which I then add to the router's wireless permissions page. Once the gaming adapter is allowed to communicate with the router, you'll be one step closer.
Odds are this club has some IT people that live for this stuff, and can help you sort it out.
