Anonymous users2024-02-03Summary. This problem may also be a DHCP problem, we can right-click on the desktop "Network" or "Network Neighbor" to select "Properties", then select "Change Adapter Settings", double-click "Local Connection" and click "Properties", then click "IPv4 Protocol Configuration" and select "Properties" to automatically obtain IP and DNS, and our computer will automatically obtain the IP address. If these methods can't solve the problem, reinstalling the NIC driver is the best way.
After unplugging the network cable, wait 5 minutes before plugging the network cable back in. Our IP is generally not fixed in the LAN, unless you set a certain IP address, so when you unplug the network cable and plug it back in, your computer will automatically search for a suitable IP **.

If these methods can't solve the problem, reinstalling the network card driver is the best way to stop the team.
To reinstall the network card driver, first right-click "My Computer" to open the "Macro Closure Manager", and in the pop-up dialog box, find a "Network Adapter" and put it. After that, we can see the network card driver on our computer, right-click on the driver, click "Uninstall" and "OK". Then right-click on the first line of the Device Manager, which is the option for our computer devices, and click on "Scan for Hardware Changes", and then follow the prompts.
We can also install or upgrade through some driver software, and we can also solve the problem and be able to **.
I hope mine can help you, if you are satisfied with my service, please give a thumbs up, and I wish you a happy and prosperous new year!

Anonymous users2024-02-02If the Ethernet does not have a valid IP configuration, it may result in the inability to connect to the network. Here are some possible solutions:
2.Reset the network adapter: In your computer's network settings, find the problematic Ethernet adapter, right-click and select it"Disabled", then right-click again and select"Enabled"。This will try to reset the adapter and regain the IP configuration.
At this point, you need to know the IP address, subnet mask, and default gateway of your network. In the network settings, select Manually configure the IP address and enter the correct information.
4.Restart your router and modem: Sometimes, the problem can be with your router or modem. Try powering them off and waiting a few minutes, then plugging them back in and waiting for them to restart. This helps to clear up network failures where the Submarine Sail is present.
5.Check the network car connection cable: Make sure that the Ethernet connection cable is not damaged or loose. Try to eliminate the problem caused by the cable itself by replacing it.
6.Contact your network service provider: If none of the above methods work, it may be a problem with your network provider. Contact their technical support department to inform them of your situation and ask for their help.
Please note that these solutions are for informational purposes only and the specific steps may vary depending on the operating system and network settings. If you are not familiar with the operation and information system and network settings, it is recommended to consult a professional or technical support.
If you want to use a router, assign an IP address. Within 10 computers, you can buy one for about 100 yuan. >>>More
Implementing PowerLink on FPGA, in fact, does not require too much hardware knowledge (software solutions), there are many open sources, as long as you build a soft core project according to Wang Jinqiu's tutorial (about 3-4 hours of learning time), the rest of the software porting is also convenient, and ready-made examples can be used directly. The rest of the application modifications and applications are mainly C language programming, so what is needed is mainly C language programming basics. >>>More
