Q：Why do we need to change the MTU value?
A：Most of the network devices’ MTU value is 1500. When your machine’s MTU value is greater than the gateway, then the large data packets will be fragmented in order to transmit. This will produce a lot of packet pieces, increase the packet loss rate and reduce the network speed. Setting the machine’s MTU value smaller or the same with gateway MTU value can reduce the packet loss.
Sometimes, your computer is connected to the Internet, but it takes very long time to open a webpage or even can’t open at all. In this situation, you may need to login the router’s homepage to change the MTU value.
Steps are as following:
1. Login the management page of the router.(the login IP is default to be 192.168.0.1,username and password both are admin)
2. On the router’s homepage, please click Advanced settings, then click WAN settings, it will guide you to a page as follows:
You need to decrease the MTU to the range from 1400 to 1450, instead of 1500. The MTU cannot be less than 1400 in general. Please click Apply when you finish it.
After the setting, you can enjoy your Internet with lower packet loss rate and better network speed.
