360 wireless / mce wired. mce wont connect

[ironape2]

Setup:
xbox 360 (A) connected via wireless N wifi adapter. Connects to internet, xbox live, and streams netflix with no problems.
xbox 360 (B) connected via wired to router.
MCE PC connected via wired to router.

I cant get 360 (A) to connect to MCE when I use a wireless connection. Im guessing its because the MCE PC is wired and this puts it on a different network? How do I get the wireless xbox to see the wired mce?

Thanks in advance.

Does (a) connect to the PC while (b) does not? Double check your dhcp settings on both the router and the xbox.

Yes, (A) connects to MCE because the PC and (A) are both on the wired network. If I connect (b) through a wired connection it works also. When I switch a or B to wireless it doesnt see MCE. It pulls a ip because it can get on the internet.

Ah, I see. I misread the first time.
That's quite the thing. I wonder if windows is blocking certain IPs from connecting for some reason. Coming inon a different port or some such nonsense. That's just weird.
