Last night I played Halo on Xbox Live. I jumped on today to check something, but XBL wouldn’t work. I ran the test and it said my “MTU” settings weren’t set right. Nothing was changed from last night. The modem and routers are all the same. I power cycled my modem, router, and 360 and tried again. Same thing. So, I went to my router page and changed my MTU settings (which were set at 1364). I changed them to 1365, 1400, and 1492 (the highest my MTU settings can be set), and tried to sign on to XBL each time. Still doesn’t work. I called XBL and am currently on hold, haha. Hoping someone can give me a solution so I’m not stuck on the phone all day! I’m completely at a loss for where to go from here and any help would be greatly appreciated!
