Trying to set MTU settings - it says "run as administrator" - I AM administrator

  1. trying to set up an xbox live connection through a laptop with a mobile broadband usb dongle. I've set up the connection no problem, now i just need to set the MTU settings.

    I'm doing this through command prompt with the command "netsh interface ipv4 set subinterface "Local Area Connection" mtu=1364 store=persistent"

    and it came back with the message "the requested operation requires elevation <run as administrator>"

    this doesn't make sense as I am logged in with the ONLY user account, and i checked the account settings, and it is definitely the admin account (it would have to be, as it is the only account on the laptop)

    i dont understand the problem

    can anyone help?

    thanks in advance for your time

    I could be wrong, but do you not need to elevate to admin to do that command in cmd?

    I didnt think it ran as admin all the time, but I'm more of a linux person...

    It looks like you could shortcut cmd.exe to the desktop and in properties select to run as administrator...

    You can do that, or just go to start menu -> all programs -> accessories -> right-click the command prompt link -> run as administrator. By default it's not elevated even if you are an administrator.
