If you find yourself in a similar situation, you may want to reset network settings on your Mac. There are several different settings you can reset and the details can be daunting. No fear; We'll tell you what to try to troubleshoot your network problems.

Why might you need to reset network settings on your Mac?

However, there may be times when you cannot connect to the Internet or browse websites. Wi-Fi is working, the internet is available on all of your other devices, but for some reason your Mac can't connect.

Before going any further, make sure that the problem is with your Mac and not with your Wi-Fi connection itself. An easy way to do this is to check the internet connection indicators on your router. You should also check that the internet is working on another device (iPhone, iPad, etc.) connected to the same WiFi network.
