Ethernet doesn't have a valid IP configuration - Help please

justintime2001 · 22 Jun 2021 at 11:06

I am having a problem with a new PC. When going to a search engine, the first search always comes up with the error "Ethernet doesn't have a valid IP configuration". I click the fix link and all is then well. However after a reboot the error is back. I have tried all of the following but still have the problem. Any advice would be appreciated. Thanks.

Fix #1. Restart your Modem, Router, and Computer.
Fix #2: Disable the Fast Startup feature
Fix #3. Configure your network adapter settings.
Fix #4. Reset TCP/IP.
Fix #5. Clear the network cache.
Fix #6. Reinstall/Update your Network Adapter Driver.

Need a bit more information before anyone is likely to be able to suggest a solution:

How is your computer connected (wired ethernet, wireless, or wired using powerline adapters)?

What router or firewall devices are you using?

Are you using static IP addresses or DHCP (DHCP pool size / lease time / any MAC reservations)?

Hi.
Computer connected via Ethernet.
Router is a Sky Router
Windows firewall
DHCP I think.

Have you run any and all available updates for the OS?

All OS updates have been installed. If I just restart the PC it remains ok but when switched off and then on again the problem returns.

Make sure your ethernet connection is fully set to DHCP, with no extraneous entries.
