hey furry. Did what you asked. Edit settings on router, tuned off xbox, restart router with UPNP, Xbox on started up halo 4 and black ops 2 still moderate.
Reset router to default, my TESTED BANDWIDTH changed to DOWN 14.81 and UP 1.04, OPTED in to Streamboost updates, Reserved all Clients, XBOX 360 as my top priority, DNS relay ON, UPNP ON, only have 2.4 ON because I don't have any products that use 5.0ghz, and basically everything I listed before. Still moderate.
