Your computer's internet connection is unstable frequently.
Your computer's internet connection is unstable frequently.
My computer is experiencing a problem where the internet suddenly stops working. All I need to do is open settings and check the network card, and then it functions properly afterward. After diagnosing, I receive a warning like: "Ethernet does not have valid IP configuration (solved). Resetting Ethernet card (complete)." This message appears consistently every time I perform the steps, which is really frustrating since I have to repeat this multiple times daily.
Have you checked for a driver update? Frequent daily updates suggest it operates on an hourly schedule, potentially exhausting the IP lease without renewal. What device are you using?
Start by updating the drivers for your NIC—either reinstall if you have the newest version or download them directly from the manufacturer’s site for the most current support. If the problem involves DHCP, consider assigning a static IP address so the computer doesn’t need to request one automatically. You can also run the command ipconfig in CMD to check your settings and adjust them manually if needed.
It's notable you're employing IPv6 on a local network. I wouldn't enable it unless necessary, as it offers little benefit there. For IPv4 setup, configure the default gateway to 10.0.0.138. A typical subnet mask for a 10.x.x.x range is 255.0.0.0, though 255.255.255.0 functions well in home settings. With a 255.255.255.0 mask, your IPv4 address should fall between 10.0.0.1 and 10.0.0.254, excluding 10.0.0.138. Consider using a memorable number like 10.0.0.111 for clarity.
You need to find it in your Programs menu, go to Control Panel, select Uninstall a program, and locate the driver there. Remove it and then install the new one. In the CMD screenshot, it's notable that your default gateway isn't set correctly. The subnet mask indicates your network isn't subnetted, which suggests this might be a home setup. I wonder who or why configured the default gateway this way. If needed, you can assign a static IP address. While I can't confirm if other ISPs include IPv4/6 pre-set during installation, it's likely most consumer routers come with these options. With Windows and Linux/MacOS enabled by default for DHCP and IPv6, computers typically receive both IPv4 and IPv6 addresses. However, this can be an inconvenience when managing networks or troubleshooting. Unless you're specifically using IPv6 features like advanced subnetting or needing a large pool of addresses, enabling it isn't usually required for standard home use.
Location from top to bottom: IP Address 10.0.0.111, Subnetmask 255.255.255.0, Default Gateway 10.0.0.138, Primary DNS 8.8.8.8, Secondary DNS 8.8.4.4. These settings correspond to Google's public DNS servers.
