My brother has been trying to get his Xbox Live to work in his new place. But when running the XBL diagnostic it reports that it has detected an MTU problem and that the internet connection MTU is less than 1360!
I have checked using ping -f -l 1460 from his PC and there is definately no MTU issue on his line.
So what on earth is the Xbox doing to report this error?
We've tried two routers to no avail. First a 3com thing and then a "known good" (because it was my router literally a month ago) Speedtouch 510v4.
The XBL "works" but is highly unreliable. It keeps signing in and out and games like Fifa will disconnect after a minute or two of playing.
I can't think what else it would be
