Tp-link Router's MTU settings

The so-called MTU, that is, the largest transmission unit, which is the network transmission of the largest packet value, the General Tp-link router's MTU value is the default, changing the MTU value can increase the efficiency of the router, but the MTU value exceeds the ISP requirements will not be able to transfer, so if no special needs, it is best

If you can't open Web pages or use VPNs on the Internet, you can try to change the MTU value when you encounter performance problems, one of the following values may solve some of the problems caused by the MTU value:

1500 Ethernet information Packet maximum value;

The best value of 1492PPPoE;

1472 the maximum value of using Ping;

The best value of 1468DHCP;

Best value for 1430VPN and PPTP;

576 dial A standard value to connect to your ISP.

The method of using ping command to test the best MTU value

(1) Click Start-Program-attachment-command prompt, enter command ping–l 14xx–f www.google.com,l 14xx parameter means to send a fixed-length packet, 14XX is the packet size to test.

(2) Prompt packet is too large, need to subcontract, so that the value of 1453 is greater than ISP's MTU, should reduce packet size.

(3) packet size is 1452, indicating that the packet can be transmitted normally, so the ISP's MTU value is judged to be 1452.

(4) The above MTU value can not be used directly on the Tp-link router settings, but also on this basis to add 28, so fill in the Tp-link Router WAN Settings page MTU value is 1480.
