Win7 has the problem of "default gateway is Global trade customs valuation analysisnot available" under the Win7 operating system, many users have encountered the problem of "default gateway is not available". When connecting to the network, this problem will cause the network to be unable to access normally, causing great inconvenience to users. Here are some ways to solve this problem. First of all, we need to understand what the default gateway is. The default gateway is the key transit point connected to the Internet in the local network. That is to say, in the network, after receiving a packet, if you don't know how to transmit it to the target address, you will first send the packet to the default gateway. The default gateway then sends the packet to the target address.When sending and receiving packets, if the default gateway is not available, data cannot be transmitted to the Internet or other external networks. If the "default gateway is not available" in the Win7 operating system, there are the following solutions: the first way is to restart the router. Restarting the router is the most commonly used and easiest way to solve the problem of "default gateway is not available". We can operate by entering the IP address of the router in the computer browser, then entering the router settings page and finding the router restart option. After restarting, the router will automatically reassign the IP, so as to solve the problem. The second way is to update the network card driver. If there is a network error, the common solution is to update the network device driver. It can be found through the device manager.Network card device, and then select to update the driver, which can make the driver more stable. If the network card driver is attacked by viruses, malware, etc., it will also cause the problem of "default gateway is not available". Therefore, we should update the drivers of network devices regularly. The third way is to check the network adapter settings. Network adapters are physical hardware devices used by computers to connect to the network, including network cards, etc. If there is a problem with the network adapter settings, it will also cause the "default gateway is unavailable". Therefore, we should check whether the network adapter settings are correct. You can go to the Network and Sharing Center in the control panel to set up and repair. The fourth way is to ensure that the IP settings are correct. If the IP address setting is incorrect, it will also cause the error "Default gateway is not available".We can check whether the IP address and other settings are correct in the system settings. If not, they need to be modified. In addition to the above solutions, the following methods can also be used to solve the problem of "default gateway is not available": 1. Restart the computer. Sometimes, the problem of "default gateway is not available" will occur after the computer is connected to the network. Restarting the computer can solve this problem. After restarting the computer, you can reconnect to the network. Two. Release and update IP. You can release and update the IP address by opening the command prompt and entering the commands: ipconfig /release and ipconfig /renew. In this way, the network adapter can re-obtain the IP address and solve the error that the default gateway is not available. In short, the problem of "default gateway is not available" is one of the common errors in network connection in the Win7 operating system.We can solve the problem through the above methods, make the network connection more stable, and ensure that we can speak more freely. At the same time, maintaining computer hygiene and safety at ordinary times is also an effective way to reduce the occurrence of this problem.
