MTU Value

[Casino]

For the stability of my internet, i need to set my MTU (Maximum Transmission Unit) value, in my case is 1492.
I read that this value can be changed, generally, in the router settings, but i can’t found anything in pcwrt for to change it.

How can i do? I have my modem/router (TP-Link) on Bridge Mode.

It’s on the Internet Settings page.

Where? Override MTU? Why the box is blank without no one value into it?

The simple “MTU” and “Override MTU” are the same thing?

Override MTU. Entering a value there will override the default value, which is 1500 when left blank.

Thank you so much.

I can’t change the MTU. The change has no effect, i’ve changed the value in the internet setting, but my MTU is always the same. Look here:

With the command “netsh interface ip show interface”, (specifi command only for windows xp), it shows me that my MTU is always 1500, also with the program “TCP-Z”, it shows me that the value is 1500.

I’ve rebooted my modem, pcwrt and the pc also. Nothing.

The change has no effect on your Windows machine, it only changes the outbound MTU on the router. You can Google “how to change MTU on Windows” to find out how to do it for your PC.

Thanks, but how can i see if the router is working on 1492 or at 1500? There’s a way to see it?
