[Cable] Upload packet less than MTU, But path MTU is on

I'm getting an insufficient MTU rating on my Xbox 360. It needs a minimum of 1364. My Tweak test is saying Max packet recd (MTU) 1470. I'm assuming this is my actual MTU setting. I've got all my ports opened for the xbox 360, and I even have it set on DMZ.

Under observations in the Tweak test it says Upload packet less than MTU, however my Path MTU discovery is ON... So I'm assuming this is why my xbox is giving me this error.. but I don't know how to fix this issue. Under faq it tells me to turn path MTU ON.. but it already is.

Any help appreciated.

What MTU does the router show?

Run a Tweak Test on your box (not the xbox) without the router.

My router does not seem to have an MTU setting in the interface. It is a known issue. My computer is connecting to the internet through my router though. Is there some sort of tool I can get to view and change my router's MTU? If I'm getting these tweak results and I'm connected through the router wouldn't that mean that my MTU setting on the router is good?

• Just DC the router.

• Reboot the MODEM.

• Run a Tweak Test. and pot the URL for it.

• connect the router to the MODEM. When the router syncs, reboot the MODEM.
