Yes they do match up. Once I used Toolbox to enable DHCP, the router assigned 192.168.1.111 to it. I then set the IP up as static through the router interface to prevent the lease from expiring. The IP in the iPhone settings is exactly 192.168.1.111.

The only things I can thing of at this point are using the original Linksys firmware. Hopefully the processor is not busted. If there was some kind of diagnostic I could run, that would certainly be helpful. The PMC2s seem pretty robust from what I've read so far. The previous owner had no issues with it.

Thanks again for the help. I'm pretty sure I've covered all my bases, but it seems like network connectivity between the PC and the processor, the PC and the iPhone, and even the processor to the iPhone just isn't working right.
