What to do The IPv4 of the network has no network access There is no router installed at home IPv4 s

Are you dialing up the Internet?

Here's how to fix IPv4 without network access:

1. Fix the network connection, the network connection of Windows XP operating system has the "Repair" option, but Win7 does not.

However, you can use diagnostics, which has the same effect as repair, it can find and solve problems, and you can click "diagnose" when you encounter problems.

2. If the diagnosis doesn't work, you might as well try another method, disable it and enable it. That is, stop the network card that is now running and then reboot it.

3. Although disabling it may solve this problem when it is enabled, it may appear again after restarting the computer, the solution is to enter it in the running process first and open the local policy group.

4. Since the router is automatically assigned an IP address, this problem will occur when the same IP address is assigned to different computers, and you only need to restart the router to let it assign an IP address again to solve the problem.

5. If you want to avoid this situation, you may wish to bind an IP address to the computer, so that the computer will not be in this situation.

You can enter the network and sharing center, find the IPv4 option, and then manually set the IP address and DNS server address settings for this option, the specific disturbance method is as follows:

1. Right-click the network connection icon in the lower right corner of the computer and select the Open Network and Sharing Center button.

2. Click the Change Adapter Settings button on the Network and Sharing Center interface that opens.

3. Select the network connection in the interface that appears, and click the right-click to select the properties button.

4. Find IPv4 in the network properties dialog box that appears, and double-click the option.

5. In the IPv4 properties dialog box that appears, click Use the IP address and default gateway below.

Notes:

1. The manual IP address needs to be consistent with the IP address segment of the router, and the default gateway needs to be filled in correctly, which can be viewed in the settings of the router.

2. The above manual setting is carried out on the premise of excluding non-hardware problems.

3. The DNS server address of different network service providers and regions is different, so you can consult the network service provider.

If your computer is displaying the "IPv4 No Network Access" error message, it may be caused by one of the following reasons:1Network Connectivity Issues:

If multiple computers use the same IP address, there may be IP address conflicts, resulting in inability to connect to the network. You can try changing the IP address or assigning an IP address using DHCP. 3.

Network firewall: If you have firewall software installed on your computer, it may prevent your computer from connecting to the network. You can try turning off the firewall or adding network access to the firewall.

5.Network service issues: If network services are not enabled on your computer, you may not be able to connect to the network with continuous shooting.
