    I have a rooted LG Optimus S, and I am wondering on how to change my MTU settings through Terminal Emulator, so that it will be at 1500. I don't know how to do it, but I know it's been done. I am trying to tether my Phone to my Xbox, whixh is how I am using the PC right now, and the xbox reads my IP, and DNS, only issue is the MTU. So if someone could, just let me know how to do it

    I tried the commands for Linux, but that did't work since eth0 and eth1 aren't recognized as inputs.

    I have found where the MTU files are, in /class/network or /net. But they are all above 1500, so it is something to do with a much higher file rather than those.

    I'm not even sure you can set the MTU for 3G or Wifi even.

    A Google search found the following:
    1) An Android bug report - Issue 1008 - android - let user specify MTU per wireless access point - Android - An Open Handset Alliance Project - Google Project Hosting
    2) Something for the Dell Streak (different device but still applies) - MTU on 3G interface - Android @ MoDaCo

    So then do you all think that maybe it is Sprint locked? I've seen some of the other Android phones have quick changes applied to their MTU, but the Optimus seems to the be hardest of all.

    Is there a reason why you want to change the MTU? Unless you experience problems usually this value doesn't have to be changed.
    Anyhow, if you really do want to change the MTU, do this:
    adb shell busybox ifconfig rmnet0 mtu <mtu here (max 1500)>

    Phone must be rooted, install andriod terminal emulator, then type
    su
    ipaddr (thats just to check mtu on interfaces)
    ifconfig wlan0 mtu 1500
    and thats it,
    I also change the mtu on sit0, but thats me.
    hope this helps.
