well my problem is my xbox live isn working anymore. yesterday i was playing black ops:II when i got disconnected from xbox live. i didnt think anything of it at first but i tried again this morning and it still wont connect.. ive got a wired connection going directly to my 2wire router/modem. my internet is working just fine, and my live subscription should still be good. i went through the live solutions at (http://support.xbox.com/en-US/xbox-live/connecting/cant-connect-to-xbox-live-solution) but i still cant seem to find whats causing this problem. when i test my connection it stops between network and internet then says test failed, then i get an MTU error. ive tried unplugging the router and xbox for 30 secs and reconnecting, but it doesnt work. and it says a problem with your router or modem is preventing communication with XBL, but its been working just fine before yesterday, i didnt do anything to the setup of things.. the only part in the process of those steps i couldnt complete is the manual DNS server part, because i dont have a secondary DNS server number but other than that ive tried everything.
some help would be highly appreciated and i would love you for getting me back on during this double exp weekend ^^
if more information is needed just ask, and ill try to reply as quick as possible. thanks so much!
