Trying to connect to wifi on my Mac

It would be most helpful if you were to explain to us what your problem is. What is or is not happening. Normally, if you have a functioning Wi-Fi available, you can select it and connect to it via your System Preferences app. Click on the Network button. On the left side of the window will be a Wi-Fi button. Click on it and then you will have two important things on the right side. At the top is the Status. It has to be turned on to b Connected. Down below is a scroll window that allows you to select the specific Wi-Fi network you want to connect to. Most will require that you enter a password to connect. If no Wi-Fi network is shown, then your modem is not functioning correctly and that will have to be addressed.

Make a New Location, Using network locations in Mac OS X ...

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.

If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.

System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

8.8.8.8

8.8.4.4

1.1.1.1

9.9.9.9

Apply.

Is this done?

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.
