log into router.find ur device tick always use same ip then put that ip in dmz.then on your xbox use auto settings

I would look to buy a different router.
Setting a device behind your network as DMZ is a security risk and not really recommended (even though it might resolve the issue).

See some of the other recent threads about gaming issues. Popping up more and more that the PN router is awful for gaming. Save yourself the hassle and buy a decent one (ASUS seems to be a popular choice) and put a hammer through the PN one.
