Issues with Ethernet adapter occur when the connection fails to establish or function properly.
Hello, I'm facing some difficulties: occasionally, the internet stops working on my PC randomly. All other devices function normally except my PC connected via Ethernet. I've tried various solutions like running ipconfig /flushdns and following tutorials on YouTube and forums, but they only offer temporary fixes lasting a day or two. The issue happens unpredictably throughout the day, which is really frustrating. I reinstalled Realtek's Ethernet driver, which worked yesterday, but today at 3:50 P.M. PST, the cable and connection are present, yet it doesn't connect to the internet or web pages—only Google searches work. I've checked cables, router connections, even reset the router and scanned for malware using Malwarebytes and Avast, but no threats were found. I'm currently using a USB-to-WI-FI adapter, which seems to resolve the problem quickly. I'm wondering if you could suggest alternatives or explain why a USB-to-Ethernet adapter might be a better option. The situation started around last month and is intermittent, though it worked occasionally until recently. The pictures you mentioned show what happens when I connect via Ethernet.
USB to Ethernet adapters perform well. Often the issue lies in IP settings or the router assigning the same address to several devices. Setting a static IP within the correct range might help. Try turning off IPv6 as well—perhaps it’s the source of the problem.
I suggest reinstalling Windows as a final option since you and your brother have already explored settings, static, and other methods without success.
I've changed the cables and adjusted the settings on the LAN card, but it's still not working. I'm planning to reinstall Windows.
It seems the system is linked to the internet, but only specific sites like YouTube and Twitter are accessible. I may need to reinstall Windows to obtain the right drivers, and I should also clean the registry since it might have a virus from the last scan.
It isn't a Windows issue but relates to DNS cache, LAN card, or router. Have you tried switching to fixed DNS addresses like 8.8.8.8 and 8.4.4.4? Checked both in Windows and the router. Yes, you can reinstall the system—it's not a permanent fix, but it's an option. Ideally, consider installing the system on another drive just in case the problem persists after a fresh setup.
I recently encountered a problem believing my onboard Ethernet port was dead, only to discover it was just a faulty cable. I spent time replacing all my cables and upgraded from Cat 5 to Cat 7 for better performance.
I had it and it functioned briefly. It happened when I and my brother restarted the router and also configured the DNS addresses 8.8.8.8. I thought maybe the built-in LAN card was the issue. The Ethernet port lights up, but sometimes the internet connection doesn’t work.
Ensure the motherboard and Ethernet port are free of dust; sometimes debris can cause short circuits. (You must remove the motherboard from its case.) 2. Verify the RJ45 pins on the cable are clean and functional. Test it with various laptops or PCs—if problems persist, the cable might be faulty. 3. Perform a complete uninstallation: remove any existing files, then reinstall the Ethernet driver from the manufacturer’s website. Disable Windows 10 auto-updates for drivers to prevent issues. 4. Likely some software is interfering; list running programs and uninstall them. If that doesn’t help, consider purchasing an affordable USB-to-Ethernet adapter (USB 3.0 or higher) or a USB to Wi-Fi/Wi-Fi card. All these options are budget-friendly.
