3 Solutions to Resolve Mac Not Detecting Wi-Fi Networks
Fundamental Resolutions:
- Toggle Wi-Fi Off and On: Begin by restarting your Mac. After rebooting, navigate to the Control Center on your Mac to turn off Wi-Fi, and then turn it back on after a short period.
- Reboot Your Router: If your Wi-Fi does not appear on any smart devices in your home or workplace, your router might be at fault. A quick reboot of the router can resolve this issue.
- Upgrade Router Firmware: Running on outdated router firmware could disrupt your internet experience. Keep in mind that the procedure for updating firmware can vary by manufacturer. It’s advisable to visit the official website of your router’s brand for specific instructions.
- Check for Service Outages with Your ISP: If your ISP is experiencing an outage, this may result in your Mac being unable to locate any Wi-Fi networks. You can verify this by visiting Downdetector and searching for your ISP’s status.
Solution 1: PRAM Reset
Resetting your PRAM effectively clears your Mac’s current state data and restores its default configuration. This includes resetting display settings, sound preferences, time zone, and more. Here’s how to perform a PRAM reset.
First, power down your Mac. Then, press the power button and simultaneously hold the Command + Option + P + R keys for approximately 20 seconds. Release the keys once you hear the startup sound.
Solution 2: Delete Network-Related Plist Files
If your Mac doesn’t display the office Wi-Fi network, removing the network-related plist files may resolve the problem. Follow these steps:
Step 1: Disable Wi-Fi on your Mac. Then, open Finder and press Shift + Command + G. Input the following path:
/Library/Preferences/SystemConfiguration/
Step 2: Locate the following plist files related to networking:
- com.apple.airport.preferences.plist
- com.apple.network.identification.plist
- com.apple.wifi.message-tracer.plist
- NetworkInterfaces.plist
- preferences.plist
Once identified, right-click on each and choose to move them to the Trash. Right-click on the Trash again to empty it, then restart your Mac.
Your system will recreate the necessary files when it restarts, which should enable the nearby Wi-Fi network to be detected by your Mac.
Solution 3: Remove Unnecessary Files on Your Mac
Step 1: Launch Finder and press Command + Shift + G. Input the following directory:
~/Library/Caches
Step 2: Highlight the items you wish to delete and then move them to the trash.
You can also opt for third-party software such as CleanMyMac X for clearing the application cache on your Mac.
