My Desktop/Storage PC went down during a power outage. After power was restored, I found that I couldn't surf the Internet. I checked the LAN interface in Network Connections and found that it didn't have any TCP/IP values. Usually, they have at least 0.0.0.0 as its IP and Subnet Mask but in this case, it was just blank.
I tried disabling and repairing the LAN network connection but its TCP/IP values were still blank. After I tried repairing the connection, I got this message - "Failed to query TCP/IP settings for the connection." I also tried disabling and enabling the IPX/SPX and TCP/IP protocols and then tried removing them but all that didn't work.
After a bit of research, I uninstalled all my Network adapters in Device Manager and rebooted. My network adapter was immediately detected again after startup. This fixed my LAN network connection and I was able to surf again.
