Wi-Fi Settings

If you were getting the same message on your Mac recently, most likely you will have to reset the location of your Wi-Fi or assign a new lease. In both cases, your first call is your computer’s Wi-Fi settings, and here is how you can check if those are correct:

  1. Go to Menu > System Preferences > Network.
  2. The first thing you should be looking at is the Location. This parameter should be set to automatic by default, and if it’s not, that might be the main cause of your issues. In this case, you need to launch a dropdown menu and select the automatic option.
  3. Next, go to Advanced > TCP/IP
  4. Now, you need to look at the parameter called Configure IPv4 is set to Using DHCP option. If not, change it.
  5. Next, look at the first Router line and ensure that it shows an address. If not, you might need to reboot the system and try again.
  6. After that, look at another parameter named Configure IPv6 and make sure it is also set to Automatically and if it is not, change this setting.
  7. Apply changes by clicking OK.
