I removed all encryption, and left it in the default mixed mode for N, B, and G.
Connects just fine.
Again, I tried it with different versions of the Pro/Set Wireless tools, and they are giving me problems.
It didn't do this with 1.11, or 1.10. So, it's definitely either something with the drivers, or else a compatibility with the firmware itself.
Somewhere though, it has trouble authenticating itself.
Thanks!
Edit: Here's the router logs regarding it.
