macOS Sierra 10.12.6 self assigned IP

I am running Sierra 10.12.6 on my macOS desktop, and all of a sudden I am not able to get on the internet. I have tried several steps to no avail. I have even called my ISP, who advised it is probably a hardware issue since everything else in my house is connected, and not having an issue.

I have tried the following:

To reset the firewall, go to the /Macintosh HD/Library/Preferences/ folder and remove the file called "com.apple.alf.plist," and then restart your computer. After the system boots, you may be prompted to allow incoming connections to numerous programs and services, so accept these for now (you can always go to the Firewall settings and deny or remove entries later on) and then try connecting to the network again. While configuration changes from migrating or restoring a system can lead to this problem, at other times major system crashes or power outages can do the same.

I have also tried: For Resetting Wifi Configurations:

step-1) Go to Desktop and press command+shift+G
step-2) Go to the /Macintosh HD/Library/Preferences/SystemConfiguration/ folder
step-3) Backup and remove following files:
com.apple.airport.preferences.plist
com.apple.wifi.message-tracer.plist
NetworkInterfaces.plist
preferences.plist
step-4) Restart your computer.

Nothing seems to be working. Any ideas?
