Anyone know how to change the MTU size on a comcast router?

[purbeast0]

I am not at his house or anything but I tried to step him through how to change the MTU size, atleast on my linksys router. However he cannot find the MTU field on his router settings.

He needs to up the MTU setting for xbox live to work. Does anyone know how to change it on a comcast router? Thanks!

?Comcast Router? is Not a Manufacturer and a Model number of a Router.

Logig 101, it means the Router that they gave you or one that you got to work with your Comcast Internet connection. How should we know?

In addition, most current Routers set their MTU automatically to type of Internet connection that they are configured for.
