Set MTU for intenet
- Sorry that my question is not specific to win7. I could not find a general networking forum. Hope you network gurus can help.
MTU is bound to network adapter:
MTU
Key: Tcpip\Parameters\Interfaces\interfaceGUID
Value Type: REG_DWORD—number
ping -f -l [packetsize] [www.yourisp.com] is used to test for the MTU value (try different sizes until unfragmented packet gets back).
On my machine, I have two network adapters, one local Ethernet, one wireless. As far as I can see, both are connected to internet. How do I specify adapter in using Ping to get MTU value for each adapter and then I can change the registry accordingly?

- The simplest way might be to disable one at a time. You could, for example, temporarily unplug the Ethernet cable, or disable the radio.
Sorry for stating the obvious.
Are you experiencing a specific problem that's got you looking to change your MTU size, or just trying to do tuning in general?

Thanks Noel! I just try to do tuning in general.
I wonder if I use socket API to ping, there should be a way in winsock for specify an adapter.
