Yes, a damaged Ethernet cable connection point could prevent you from accessing the internet.
Yes, a damaged Ethernet cable connection point could prevent you from accessing the internet.
I recently encountered an issue with one of my main Ethernet cables at home. I noticed the connector head was missing, but I assumed it wouldn’t cause any problems. After plugging it into my computer, I realized my internet connection was down. I attempted troubleshooting on Windows 10, but received the error "ethernet doesn't have a valid IP configuration." I tried using a cable tie to mimic the missing clip, though it didn’t help. Since I don’t have direct access to my modem (it’s installed in the roof) and haven’t updated my network drivers, I’ve tested multiple IP addresses—including 8.8.8.8 and 8.8.4.4 for DNS—to see if that resolves the issue.
The clip stops the cable from coming loose in the port. When the cable touches and your PC shows a connection (like pinging the router at 192.168.0.1 or seeing an IP error), the clip isn’t the issue. If you confirm your PC is using "Ethernet" but still has problems, it’s likely another problem.
Well, if the issue isn't with the clip, maybe it's related to my IP address. I've tried using the netsh command in the command prompt (as admin), and after changing the IP via ipconfig/release and /renew using 8.8.8.8 in IPv4, the error persists. The problem seems to be an invalid IP configuration. Even though I updated my network adapter drivers, the issue remains unchanged. If possible, someone could walk me through a step-by-step fix, since it doesn't appear to be hardware-related.
