just tried to plug in my xbox360 in to my cable stb (had to move stb from down stairs from upstairs) to go live (i use same box for pc internet)

but it comes up with a mtu fail and needs a min of 1362.

so have plugged in pc, but how do i see what my stb mtu speed is?

Google found this, which seems to have some instructions for ntl.

p.s. MTU isn't speed, it's the size of the data packets that go through the network.

I use DrTCp from here when I've had to play around with MTU settings.
