Okay first off my router is a Cisco Linksys E1200 and yes the MTU is on 1364.
Second i was not having an issue with my router yesterday everything was fine i was on live talking to friends watching Netflix the usual. But now today i start my Xbox up and it doesn't connect to live. Im thinking okay maybe Live is down but i look at my friends on Xbox.com and they are playing games so now im thinking it is my router (which it is). I have been trying to get online for an hour now and i have done everything that was posted in the sticky about MTU issue and nothing. It seems that Xbox live is very freaking sensitive with this crap and it is annoying. Can anyone help me out?
Also i cant move my router closer to my Xbox because of positioning issues but i would say its about maybe 3-4 feet away from my Xbox. Also i should mention my xbox is the new slim so its wireless.
