1. Set the (data) checksum checksum Offload Set the (data) checksum checksum Offload parameter to Disable
2. In the NIC settings, remove the "allow the computer to turn off this device to save power"
3. In the power management system, check the box for energy saving.
Many integrated NICs cause these problems. And Blizzard's official blue post has long proposed the above solution, the official blue post said that in addition to this checksum offoad, there are two other places and wow network compatibility problems. Both are in the NIC options. One is in the power options, turn off the "allow the computer to turn off this device to save power", the other is and checksum offload a piece of, called Speed/duplex, the default is automatic, change to force 100 or force 10. Both of these points can help improve the network. If you have an integrated NIC, look for these three items in the NIC options. If you don't have these three items, install a standalone NIC, which will also work. checksum offload is to hand over part of the checksum of the network packets to the NIC, thus reducing the burden on the cpu. And the integrated network card may have problems with the checksum of wow packets. That's why the wow program is blocked. Another way to increase the stability of your network: update the driver of your network card, make sure to use Microsoft certified driver. Don't overheat your ADSL cat. Network cable connectors should be good, press them firmly. The cable should not be too long, and so on.
MTU is the abbreviation of Maximum Transmission Unit. MTU is an abbreviation for Maximum Transmission Unit, which means the maximum number of packets that can be transmitted over a network. The MTU of most network devices is 1500. If the local MTU is larger than the MTU of the gateway, large packets will be split and transmitted, which will generate a lot of packet fragments, increase the packet loss rate, and reduce the network speed. Setting the MTU of the local machine to be smaller than or the same as the MTU of the gateway can reduce packet loss. Modification methods are as follows: (1), run regedit (2), browse to: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersInte***ces (3), Inte***ces under a number of sub-items, each sub-item corresponds to a network card. Each sub-item corresponds to a network card. Please select the NIC as follows: (a) Determine the IP of the NIC or dial-up connection used by this machine to connect to the Internet, such as 192.168.0.2; (b) Click on the sub-item of Inte***ces with the mouse, and check the IPAddress item in the list of keywords; (c) If the keyword of IPAddress is the same as that of (a), that is, 192.168.0.0; (d) If the keyword of IPAddress is the same as that of (a), that is 192.168.0.19, then that sub-item is the NIC to look for. (4), into the sub-item, in the right window, press the right mouse button, select "New" - & gt; "double byte value", enter the name "MTU", press Enter. Double-click "MTU", a modification window will pop up: Fill in the value of MTU: 1492, before filling in the base number, please set the base number to decimal. After setting, you need to reboot the machine to take effect. If you really don't know how to do this, please use a tool such as WINDOWS Optimizer to optimize your network system by changing the Maximum Transmission Unit size to 1492. If you are using a router, please change the MTU to 1492 directly in your router's WAN options
See what kind of problem you are having.
