[quote][b]Posted by:[/b] Jeff the Pickle hey everybody i need help. my xbox live is screwed up, i ran the tests this moring and its says MTU failed.. would somebody please tell me what htis means?[/quote] If you have a router, you need to check what your IP Address is. Once you have figured this out, open your browser. (mine is internet explorer 7.0 so if you have that it should work, probably with any other too though) In the search bar type in your IP Address exactly with the dots and everything and press enter. I have a linksys router..dunno if it works with other routers..but a type of log-in screen should pop-up. On my computer, I dont give a log in name just in the password column type 'admin' and you should be ok. If you got in, you should be able to access all of your router configuration settings. MTU is on the first page of settings for mine, you may have to search around depending on brand, again this is all what I do on my computer when my XBL fails MTU. If MTU is disabled, enable it and the Max MTU should be atleast 1500 I think. Thats default for mine and it seems to work. I think MTU is like maximum transmission unit or some jibba jabba but probably has to do with data idk. Anyways, thats how I fix it. To get your IP, (if u have windows XP) go to Start, My Network Places and there should be a Network Tasks panel on the left. Click view network connectionsand double click Local Area Connection. A panel should appear, in the tabs, click Support and your IP Address should be clearly displayed. (use the IP Address ONLY for this, you shouldn't need to worry about Subnet Mask or Default Gateway. P.S. -----I'm not a nerd, I just get pissed when My Live won't work and go to great lengths to fix it. =)
