If you set the MTU size for a network interface manually, this setting overrides the default MTU for the network interface. The MTU size is the maximum packet size in bytes the transport will transmit over the underlying network.
This method affects packets sent to all destinations and may significantly affect the performance, depending on the MTU size that you set.
To set the MTU size for the network interface, follow these steps:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<ID for network interface>
Get your IP address by type: ipconfig at the command prompt
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type MTU, and then press ENTER.
5. On the Edit menu, click Modify.
6. In the Value data box, type the value of the MTU size, and then click OK.
*1360 is the sample date
7. Quit Registry Editor, and then restart the computer.
Caution: Serious problems might occur if you modify the registry incorrectly
