What Causes the Ethernet Doesn’t Have a Valid IP Configuration?
The Ethernet doesn’t have a valid IP configuration problem is caused by a wide range of issues, including fast startup issues, wrong manual DNS configuration, and router problems. Other common problems like the wrong network adapter and bad ethernet cable also lead to this error.
– Fast Startup Problems
If the Ethernet IP problem is happening on low-end hardware running Windows 11 or 10, then the issue may be related to your fast startup settings. Disabling fast startup might help you fix the problem.
– Incorrect DNS Configuration
If you’ve recently changed your DNS settings, whether manually or via a third-party app, then the Ethernet doesn’t have a valid configuration issue might be a result of the change.
Your computer may be having issues retrieving data from your network, thereby causing the error. Simply reconfiguring your Windows to automatically get its DNS data can help you fix the problem.
– Incorrect Network Adapter
If you started experiencing the Ethernet error after migrating to Windows 11, then the problem might be your network adapter not being compatible with your current OS. Since the Ethernet driver belongs to an old OS, it might be having conflicts with the properties of the new operating system, thereby causing you to experience the Ethernet doesn’t have a valid IP issue. To fix this problem, you can try uninstalling the old network adapter, thereby forcing your Windows 11 to download the generic version that’s suitable for it, or reinstalling the driver and resetting your network configurations.
– Router Cache Problems
If your data is holding on to inconsistent DNS cache data, then you’re likely to end up getting an invalid Ethernet IP configuration error. In this case, resetting your router or simply restarting it can help resolve the issue.
– System File Corruption
While it might be a stretch, there have been cases where this Ethernet error has been a result of a system file corruption, with the system being unable to retrieve network-related data. You can either use a third-party restoration app to find the cause of the issue and fix your system files or reinstall your operating system.
– Bad Ethernet Cable
If you have a bad ethernet cable, then you’re likely to get this error on your PC. You want to make sure your cables and powerline adapters are properly connected to your router and your computer and that the cables aren’t faulty in any way.
– Disabled DHCP
You’re likely to experience an invalid Ethernet settings error if you have DHCP disabled. Unless you activate DHCP, your computer will keep having an array of network-related issues, as it won’t be able to get the right network configurations to run properly. Reconfiguring your DHCP setting and turning it on can help you fix the problem.
– Faulty Network Adapter Drivers
If you started experiencing this issue after a recent Windows Update, then the problem might be a result of an incorrect driver or a bug in the update.
Simply removing the update from your device can help you fix this issue.
