Well I presume there is some differences in design and handling between the router Mfrs and FW. I know that at least with older D-Link routers, I can get OPEN NAT across the board with 3 XB1s. I had a hard time getting a Linksys configured with two XB1s. Of course. I can't re-test as I'm the only xbox users now. Got a R7800 now and works well for single gamer.
