Well, I found out what my problem was. My WM6 Samsung i760 did not come preloaded with ICS (Internet Connection Sharing). This, from what I've read, is vital to WMWIFIRouter's operation. Here's a link to the ICS cab download on another forum. You have to register, but no big surprises there.

Anyway, I installed it, did a soft reset, then I reinstalled WMWIFIRouter, and everything worked. Both of my Macs are now receiving proper IP's. I made this post using it.
While I found numerous solutions which involved Registry editing, this solution works without messing around. The link above is a version of ICS is for WM5 (at least that was the message I got before I hit ok and installed it) but it works just fine. Hope this fixes it.
