Is there a way to change android phone's mtu size?

My phone is having problem with sending dat开发者_StackOverflow社区a to the network. I think I have to change its MTU size to make it work.

To change MTU settings you need a to root your phone. Search in foruns how to do it. After that your need to install a terminal emulator and check what is your network interface Run the command:

netcfg

and look at the IP address what is your desired device (wlan0, tiwlan0, etc)

then use this command

ifconfig $DEVICE mtu $MTU_VALUE

and substitute $DEVICE with device name and the desired MTU value in $MTU_VALUE

You can also see the value at this file:

cat /sys/class/net/$DEVICE/mtu
