Hello ,

Thank you for posting in Microsoft Community forum.
Based on your description, the following are some possible solutions:

1. Sometimes, a simple restart can solve network connectivity issues. Try restarting your router and computer.
2. Ensure that the network cable is well connected and try replacing the cable or using another network port.
3. Try updating the network adapter driver:
   Right click on the "Start" button and select "Device Manager". Find 'Network Adapter', right-click on your Ethernet adapter, and select 'Update Driver'.
   Select 'Automatically search for updated driver software' and follow the prompts.
4. Attempt to reset network settings:
   Open Settings and select Network and Internet.
   Scroll to the bottom of the page, find 'Network Reset', click on it and follow the prompts to reset network settings.
5. If the DHCP service is not working properly, you can try manually setting the IP address.
   Open the "Control Panel", select "Network and Sharing Center", and then click "Change Adapter Settings".
   Right click on your Ethernet connection, select "Properties", and then double-click on "Internet Protocol Version 4 (TCP/IPv4)".
   Select 'Use the following IP address' and enter a valid IP address, subnet mask, and default gateway.
6. Press Win+R, enter service.sc, and then press Enter.
   Find the 'DHCP Client' service and ensure it is running. If not, right-click and select 'Start'.
7. Attempt to release and update your IP address, and clear the DNS cache
   Open the command prompt as an administrator and enter the following command:
   ipconfig /release
   ipconfig /renew
   ipconfig /flushdns

I hope the information above is helpful.
