Might try using Linksys's online tech support and ask them. I had an issue with my WCG200 where they only advertised 2 macs on the box but I was detecting a 3rd one that was only a couple numbers off and they did alot of digging and determined it was a 3rd mac for that device. They may have had other people complain about your problem and be able to help fix or at least let you know whats wrong. or a fix is being worked on.
