Experts answer: (reproduced) MTU is MaximumTransmissionUnit acronym. Means that the biggest on the network to send packets. The unit is byte MTU. Most network equipment MTU is 1500. If the machine than the gateway's MTU large MTU, Large data packets to transmit will be apart, this will have a lot of data packet fragmentation, packet loss rate increases, reducing network speed. To this machine than the gateway's MTU is set to MTU smaller or the same, you can reduce the packet loss. How to detect the gateway's MTU? Open the dos window in the machine, do: ping -f-l1472192.168.0.1 where 192.168.0.1 is the gateway IP address, 1472 is the packet length. Please note that the above argument is "-l" (lowercase L), instead of "-1." If you can ping pass, that the packet does not require unpacking,Can be sent through the gateway. If there is: PacketneedstobefragmentedbutDFset. That need to disassemble the packet to send. At this point, reduce data packet length, then the implementation of the above ping command. From 1400-1472 more than betweenTest several times, will be able to find a suitable length of the packet. The length of the data packet header plus 28 bytes of data, get MTU value. If detected, the gateway MTU value is 1500, not require modification. If you have a firewall gateway ping unreasonable, you can try directly to the MTU set to 1400.How to modify the machine MTU? Amended as follows: (1), run regedit (2), navigate to: HKEY_LOCAL_MACHINE * SYSTEM * CurrentControlSet * Services * Tcpip * Parameters * Interfaces in Figure 2 (3), Interfaces, under a number of sub-items, each sub-item corresponds to a card. Please click the following Methods NIC: (a) determine the machine to connect to Internet, LAN or dial-up connection to IP, such as the 192.168.0.19; (B) with the mouse to click on the Interfaces subkey to view the IPAddress key item in the list; (c) If the IPAddress of the key with (a), the IP the same, namely, 192.168.0.19, then the child isLooking for cards. (4), enter the sub-items, in the right window click the right mouse button, select "New" - "double-byte value", enter the name of the "MTU", press Enter. Then double click on "MTU", modify the pop-up window: Figure 3: Fill in the MTU value. Please fill in the base set to 10 beforeAry. Set up, you need to restart the machine to take effect.
