I encountered a strange issue with windows 10 not connecting to wired or wireless networks and based on the description from the user had them send their laptop in for further review. Each adapter was in an identifying state and I later learned at a 169.245.x.x IP address. At first, I assumed hardware issues as both the wireless and wired adapter weren’t working (although I guess they would be on separate chips?). I suppose if I had given it more thought I might have thought what do both share…the TCP/IP stack. And that was exactly what I needed to do to fix it. So just in case someone is struggling with this issue follow the below. I can’t take credit for this fix though as I found the answer at http://www.sysprobs.com/fixed-windows-10-limited-connectivity-not-getting-ip-from-dhcp.
- Run command prompt as administrator.
netsh winsock reset catalog netsh int ipv4 reset reset.log
- Restart PC
