• Where DOES this Connect?:

Does your Mac connect to another WiFi connection? If so, but not your own WiFi, then it is something on your side. So, restart your router/modem: unplug it for 30 seconds, then plug it back in.

A Few Thoughts:

• Reset your SMC and your NVRAM:

Sometimes changes are made to the system and then settings (i.e. for the network connection) become manipulated, technically. So, reset both on your Mac. 

Next...

• Boot into Safe Mode:

Hold Down the Shift Key upon boot. Once at the login screen, release shift. See if it all now works. In Safe Mode, only necessary items load (i.e. the caches), and new preferences are set aside.

If that does not work:

• Create a New User and See if that Works:

If it now works, then it is something installed/configured on your current user that should not be. So, transfer everything over to the new user, and then trash this user. You should be good from there.

Thank you for the update!

Do you see the name of your network (the SSID)?

If not, either you are not broadcasting your SSID, or your router is down.

If yes, then try a few things:

Try Renewing your IP Address:

Go Here: Renew your IP address from the DHCP server on Mac - Apple Support

If you see an IP address, then you are connected. But, it might just have some issues.

DHCP (Dynamic Host Control Protocol) is where your connection (your computer being the “Host”) is automatically configured and IP Address and all (hence the word “Dynamic”). DHCP is what you would likely use in a Home LAN (Local Area Network).

So, perform what is provided in that link.
