I am having trouble connecting to my brother on xbox live. We are both connected to Xbox live with no issues, and both the NAT settings are Open. We can play online perfeclty fine but cannot play/connect with one another. He is using a Linksys Wireless router and i am using a Netgear Wireless router (but both are hardwired) Any suggestions or ideas as to why this would be happening? I will provide more info if needed.
