Having access to the Internet through a broadband router*** will result in a certain loss of Internet speed, which cannot be avoided. However, you can minimize this loss by changing the MTU value of your router:

The MTU value means the maximum number of packets, in bytes, that can be transmitted over the network. The MTU value is different for different access methods, and if the value is too large it creates a lot of packet fragmentation, which increases the packet loss rate and reduces network speed. The usual use of broadband PPPoE connections, the MTU value of the maximum 1492, the solution is in the registry on the MaxMTU value gradually lower, until the network is the most normal until the MaxMTU in the registry location is:

HKEY_LOCAL_MACHINE\System\ CurrentControlSet\Services\sNetTrans\00yy, the key name is "MaxMTU", where "yyy" is the entrance to the TCP/IP, with the different settings, usually between 00 and 30. It is usually between 00 and 30.

So how do you determine which MTU value is the most appropriate?

ping -f -l 1492 192.168.0.1.

Hint: "192.168.0.1" is the IP address of the gateway, and "-l" is the length of the packet. "-l" is lowercase L. If the following message appears: Packet needs to be fragmented but DF set, it means the MTU value is too big.

And if the following message appears: Reply from 192.168.0.1: bytes=1492 time<10ms TTL=128 then it means that this MTU value is feasible, but it is still recommended to try a few more to find the best value.

Problem Summary: This is one of the minor drawbacks of using a broadband router to access the Internet. Through the actual test of the speed of the Internet proved that the installation of broadband routers between ADSL access computers, in the case of multiple computers online at the same time, due to the router in the address resolution, routing distribution and other aspects of the delay, the actual speed to reach the computer than a single directly connected to the ADSL line to be a little slower
