What's going on when the local connection doesn't have a valid IP configuration?

php editor Xiaoxin, hello! "What happens if the local connection does not have a valid IP configuration?" This problem is commonly seen in network connection failures. It usually means that the computer cannot obtain a valid IP address, which leads to the inability to connect to the network normally. This situation may be caused by incorrect network adapter settings, IP address conflicts, DHCP server failure, etc. Solutions to this problem include checking network adapter settings, restarting the router, and debugging the IP address. For a more detailed answer, please continue reading this article.

You can try the following solutions:

1. First, we open the Start menu and find the Control Panel option. Click the "Network and Internet" option, find and click the "Network and Sharing Center" option, then find the "Change Adapter Settings" option and click to enter (the above operations are all performed under win7, other operating systems may be slightly different).

2. Then find the way we connect to the network. If we are using a wired connection, we will select "Local Area Connection". If we are using a wireless connection, we will select "Wireless Network Connection". Then right-click and select Properties, find "Internet Protocol Version 4", and then click the Properties option.

3. At this time, you will enter the IP setting interface. By default, the IP address should be obtained automatically. If in this state, "the local connection does not have a valid IP configuration" appears, we You need to log in to the router interface to see if the DHCP server is turned on. If not, we check Enable and restart the router (restarting the router may not be necessary).

4. If the above method cannot solve our problem, we can also set an IP ourselves. Of course, the premise is that this IP must be within the allocation range of the router. Enter the router and also find the DHCP server. Here you can set the IP allocation range. The IP we fill in only needs to be within this range.

5. In addition to the IP address, there is also some other information that needs to be filled in, and we can find this information in the "running status" of the router. Then we choose to use the IP below, fill in some of the corresponding information against the information in the running status, and then click OK.

6. Under normal circumstances, manual allocation of IP addresses can solve this problem. Of course, the premise is that your network configuration is correct. In particular, you need to check whether there is a problem with the network adapter driver. If there is a problem here, other configurations and operations will be in vain even if they are correct.

7. However, in addition to the above reasons, there may be other reasons. Various reasons will also appear when searching online, but I personally feel that those reasons are not common, and some reasons are not necessarily obvious. will cause this problem, so it is not listed here. The above reasons and solutions should be enough to solve your problem.

Notes

1. Since the operating system where this problem occurs is mainly win7, the above operations are all performed on the win7 operating system.

2. Nowadays, many operating systems have not only Internet protocol 4, but also Internet protocol 6. The one currently used most should be 4. This article is only for version 4. The setting method for version 6 is slightly different. .
