MTU settings for TP-LINK Routers

The so-called MTU, that is, the maximum transmission unit, which is the maximum information packet value of network transmission, the MTU value of the general TP-LINK router is the default value, change the MTU value can improve the efficiency of the router, however, if the MTU value exceeds the ISP's requirement, the data cannot be transmitted. Therefore, it is best to keep the default value unless otherwise required.
1. If you cannot access the Web page or use VPN, you can try to change the MTU value in case of performance problems. One of the following values may solve some problems caused by the MTU value: maximum Value of www.2cto.com 1500 Ethernet information package; optimal value of 1492 PPPoE; maximum value of 1472 ping; optimal value of 1468DHCP; optimal value of 1430VPN and PPTP; standard value of 576 dialing connection to ISP.
2. Use the Ping command to test the best MTU value (1) Click Start-Program-attachment-command prompt and enter the command ping-l 14xx-f www.google.com, l The 14xx parameter indicates that a fixed-length data packet is sent, and 14xx indicates the package size to be tested. As shown in the appearance of www.2cto.com (2), it indicates that the packet is too large and needs to be subcontracted. Therefore, if the value of 1453 is greater than the isp mtu, the packet size should be reduced.

(3) If the packet size is 1452, it indicates that the packet can be transmitted normally. Therefore, the MTU value of the ISP is 1452.

(4) The above MTU value can not be directly used for the TP-LINK router settings, should also add 28 on this basis, so fill in the TP-LINK router WAN settings page MTU value is 1480. Modify the mtu value of the TP-LINK router can solve some of the site can not open and login to the Forum and some other rare problems, there is a need for users can try to modify.
