If you want to reconfigure your router you have to:ġ. “The AirPort Express named “Base Station ****” cannot be set up by this software. While on iPhone (iOS) you will get the following message: “This version of AirPort Utility doesn’t support this base station.” Do you you have an A1084 or A1088 model? Unfortunately, these older versions of the Express are no longer supported by the newer operating systems (Mac OS X Lion, Mountain Lion, Mavericks or Sierra).įor example, Sierra OS is showing the following message:

If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.Do you still have an older Apple WiFi router?

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:ġ) Use the AirPort menu bar item to turn AirPort off, then on again.Ģ) Try to select your Wi-Fi network from the AirPort menu.ģ) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.Ĥ) In the same panel as (3), define a new location and see if you can make that work.ĥ) In the same panel, select the AirPort connection item, click the 'Advanced' button, select the 'TCP/IP' tab, then click 'Renew DHCP Lease'. It's only use is to configure an Apple AirPort base station. Apologies for not thinking to mention this before, but AirPort Utility has nothing at all to do with your MacBook's Wi-Fi connection.
