Fortunately, you can reset your network settings easily on iOS devices. For example, if you own an iPad or iPhone, you can go to Settings > General > Reset and then Reset Network Settings. When you reset your network settings, all of your Internet and network-related settings and preferences will be erased. Unfortunately, however, unlike iOS, for Macs we don’t have an equivalent feature to do the reset but there are workarounds, you can delete the WiFi interface, which in return remove all previous networks connected and its settings (I explained below how you can do this without losing your current network settings).

Method 1: Remove and add the Wi-Fi interface

Erase the Wi-Fi interface, please make sure that Wi-Fi is selected on the sidebar. Once done, click the minus (-) sign just below the left corner of network preferences to remove it. Once you remove the interface, you can then create a new one to add your WiFi network. After you remove it, click + then on the Interface dropdown, select Wi-Fi then click Create. Once done, click Apply. Here is how:

Note: Following the steps below will erase your network settings. You may want to add a new network location before going further. This will ensure that you won’t lose your current network settings. The Location feature will let you switch between different sets of network settings and preferences. If you want to do this, here is how (you can also see this documentation):

  • Go to System Preferences > Network.
  • Open the Location drop down menu and select Edit Locations.
  • Click the (+) add button. Enter a network name (untitled, home, backup, second etc).
  • Click Done.
  • Now you have duplicated your settings. You can always switch back, if needed.

    • preferences.plistmacOS Wi-Fi settings
  6. Copy these files to the desktop for a backup (you can restore them later by placing these folders back here again) and then delete (move them to the Trash) them from this folder. Make sure that they are no longer in the SystemConfiguration folder.
  7. Empty the Trash. Do not worry. Your Mac will recreate all new preference files for wireless networking.

  1. Method 2 worked for me like a charm. Glad I found your article.
    Thank you so much for sharing this information.

  2. I tried method 1 and 2, but still doesn’t work. I must also admit that I don’t have the file named ‘’, but I have ‘’. But even if I delete that file and restart, it still doesn’t work. Getting desperate, cause I’m trying to fix the prob for weeks now…

    • I have the exact same thing going on. Tried both methods without success. I also only have ‘’ and not ‘’. Did you end up figuring it out?

  3. Yes, but my problem is that I don’t have ‘’ in the first place so I can’t delete it. I’ve tried this several times but still not connecting to my home wi-fi. Can I create this plist file somehow (it doesn’t build it on restart).
