Failure problem: There are two computers to share the Internet, so the broadband router installed, but even if only one computer in the Internet, the speed is very slow.

Fault handling: Sharing the Internet via broadband routers can cause a certain loss of Internet speed, which cannot be avoided. This loss can be minimized by changing the router's MTU value. The MTU value means the largest packet, in bytes, that is transmitted over the network. Different access mode, MTU value is not the same, if the value is too large will produce a lot of data packet fragmentation, increase packet loss rate, reduce network speed. Commonly used broadband PPPoE connection, the maximum MTU value of 1492, the solution is in the registry will be MAXMTU value gradually lowered until the network is normal. Maxmtu in the registry is HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETSERVICESSNETTRANS0YY, the key is named "Maxmtu", where "yy" is the entry of TCP/IP, Varies with settings, typically between 00 and 30. The following methods are used to determine whether an MTU value is appropriate: Enter the command Prompt window and enter the command line "Ping–f–l 1492 192.168.0.1". where "192.168.0.1" is the IP address of the gateway, 1492 is the length of the packet, and the parameter "-1" is lowercase l. If the message "Packet needs to be fragmented but DF set" appears, it indicates that the MTU value is too large. If "Reply from 192.168.0.1:bytes=1492time<10msttl=128" appears, it is possible to indicate this MTU value, but it is advisable to try a few more to find the best value.
