Cannot join a match with someone on the same network

Try putting one of the consoles in the DMZ. The other workaround is to invest in a good gaming router with congestion control. I've a netduma router, can use two consoles at the same time with no NAT type issues.

The problem is that we goto college and don't really have permission to mess with network settings

You're probably up * creek without a paddle then mate.

Oh well, not much I can do about it. I appreciate the help though.

This doesnt help.... Nighthawk R7000 and still see the same issues consistently
