Connection Issue Likely Due to IP Conflict
Connection Issue Likely Due to IP Conflict
I'm not sure about the situation, but reinstalling Windows might be the final option you consider. It could potentially resolve the issues you're facing.
Sure, I understand. My setup uses a PC from 2014 and the gigabit Ethernet port functions properly. You shouldn't encounter any issues. The problem likely lies with the router, cable, or connector.
For router security, update the firmware specific to your area. It may seem minor, but changing to a different region's firmware can resolve issues. Always ensure you install the right version.
Adjust Network settings to Private mode. Enable IP Assignment - Automatic (DHCP) – since it’s already set to DHCP, the router will assign an IP address automatically each time. In the Network and Sharing Center, select Ethernet, then in Ethernet Status click on properties, go to Ethernet Properties, double-click on Internet Protocol Version 4 (TCP/IPv4), and ensure automatic IP assignment is enabled. If not, change it and save. If your PC still loses internet connection occasionally, check for other configured internet options or VPN software. As far as I understand, your PC isn’t a major issue, but occasional drops are likely router-related. Using a PCI to Ethernet adapter is a better choice than USB to Ethernet.
It doesn't seem like an IP conflict at all. What makes you think there might be one? I don’t see anything wrong with your router, unlike what @Aditya Dighe claims. If the problem were a router issue—like overheating or low memory—it would impact all devices on the network, not just your PC. If it only affects your PC, then the cause could be related to your PC’s hardware or software, or possibly a faulty cable or port connected to it.
It's odd why this occurs, but it's active now and both devices are using DHCP. There was an issue with the event viewer—specifically an error 1014 related to DNS events—that might explain why you get an Ethernet connection but not internet access. The computer could need a complete Windows reinstall. I'm still checking various settings to see if I can resolve that DNS-related problem.
Yes, exactly that's correct though only his PC was affected. It might relate to the router LAN connection. Since his sister's computer is also connected via Wi-Fi, check if the same LAN is available on her side. Try connecting her PC directly to the LAN and see if you can use the same LAN or swap the connections. Turn off Wi-Fi completely. Open Command Prompt by running 'run', type 'ping google.com -t' and let it run for 2-3 hours. Stop the ping with Ctrl+C. Check for packet losses. Look through the output for any continuous connection timeouts. If you don't see any consistent drops (three or more) and you had no internet access during the test, it's likely the issue is with his PC. I didn't suspect anything was wrong with the PC because most hardware components are quite robust compared to typical routers or cables. The most likely culprit is a faulty cable, a loose wire, or a bent connector on the cable.
When you encounter this problem, can you check your router settings or move files between your device and your sister’s computer? This helps confirm the Ethernet connection is functioning. If yes, we can also verify PC issues as @LAwLz mentioned. Perform a DISM restore and run the sfc scannow via cmd in admin mode to see if it resolves the problem. Alternatively, we could try updating the drivers. Otherwise, the DNS your PC uses will point to the router’s DNS settings.
