XBox MTU issue

[RyanL]

Got 5g last week and speeds are good but having what seems to be a cimmon problem with the MTU settings too low for xbox live.

I've seen lots of posts on this which admittedly i shoud have read before ordering but i'm just wondering has anyone managed to find an actual solution? If not it will be going back.

Same problem here.  I'm surprised three hasn't responded to this.  Might flag it with the omsbudmen as they were given notice of the problem a year ago. Most customers will not understand what is happening.
