Ethernet lacks a usable IP address
Ethernet lacks a usable IP address
Hello, I’m facing some internet issues. The yellow triangle next to my internet icon indicated an Ethernet connection issue with no valid IP address. I tried contacting my internet service provider and checked the router/modem; everything seemed fine. After ensuring ports and cables worked, I restarted my PC but it still didn’t connect. I ran various commands in cmd, changed my IP settings, but nothing helped. I searched online and found that a recent lightning storm might have affected the Ethernet port through my cable into the modem. Once I replaced the damaged cable, everything worked again except during intense gaming sessions like League of Legends, which caused frequent freezes. After considering this, I removed the motherboard and noticed it was severely damaged. Switching to a new board could be a good idea? Edited June 1, 2018 by samzap
I faced a networking problem last winter: the Windows 10 network manager said the TCP/IPv4 stack wasn’t installed and there was a corrupted socket registry entry. Even after reboots, fixing the registry or using netsock commands failed. I had to wipe the drive and reinstall Windows from a known good ISO. The issue persisted because Windows still believed the registry was damaged—this wasted two days of troubleshooting. My switch was packed in. Why did Windows mistake a corrupted registry for the problem?
