MacBook not detecting Wi-Fi: all the reasons and solutions

You open your MacBook and try to connect to the internet, but the list of available networks is empty, or the Wi-Fi you need suddenly disappears. This situation is familiar to many users. Apple, and it can arise both on new MacBook Air M2, as well as on older models with Intel-processors. In 80% of cases, the problem can be resolved without calling a service center, but this requires properly diagnosing the source.

In this article we will look at all possible reasons, according to which MacBook Wi-Fi not detecting - from trivial errors in the router settings to hardware failures of the adapter. You'll learn how to distinguish a software failure from a physical malfunction, and what commands to use. Terminal will help reset network settings, and why a simple reboot sometimes helps macOS in safe mode. We'll pay special attention to specific issues with the latest versions. Sonoma 14.4+ And Ventura 13.5+, Where Apple has changed the logic of Broadcom Wi-Fi chip drivers..

If your MacBook Pro or MacBook Air If your device suddenly loses network connection, don't rush to take it in for repairs. Follow our step-by-step instructions—in 9 out of 10 cases, the connection will be restored within 10-15 minutes.

1. Checking the obvious: router, cables, and basic settings

Start with the simplest thing—make sure the problem isn't with the signal sources. Users often spend hours troubleshooting. MacBook, when in fact the router or provider is to blame.

• 🔌 Reboot your router: Unplug it for 30 seconds, then plug it back in. Wait until it boots up completely (the indicators should be steady).
• 📡 Check network visibility on other devices: if Wi-Fi doesn't see anything iPhone, no Android- smartphone, the problem is definitely in the router or provider.
• 🔗 Make sure Wi-Fi is turned on on your router.: on some models (TP-Link Archer C6, ASUS RT-AX88U) there is a separate wireless network button.
• 🔄 Change the broadcast channel: in the router settings (usually at the address 192.168.0.1 or 192.168.1.1) find the section Wireless and set the channel manually (for example, 6 or 11 for 2.4 GHz).

If other devices connect to the network normally, and MacBook — No, proceed to the next section. If Wi-Fi isn't working at all, contact your internet service provider's technical support. There may be a problem on their end, or their equipment may need replacing.

⚠️ Attention: On some routers (for example, Keenetic) After a firmware update, the broadcast region may be lost. If the wrong region is specified in the settings (for example, US instead of RU), some channels will be blocked, and MacBook won't see them. Check this setting in the router's web interface.

2. Diagnosing macOS network settings

If the router is working properly, but MacBook Still can't see Wi-Fi, the problem is in the settings macOSStart by checking the obvious parameters:

1. Make sure Wi-Fi is turned on: Click on the network icon in the upper right corner of the screen. If the item Wi-Fi no or it's grey - click Turn on Wi-Fi.
2. Check airplane mode: go to System Preferences → Network and make sure that the mode On the plane disabled.
3. Update the list of networks: In the Wi-Fi menu, select Refresh the list of networks (or click Option + click on the Wi-Fi icon).

If these steps do not help, proceed to a more in-depth diagnosis:

• 🛠️ Reset network services: open Terminal (through Spotlight or Programs → Utilities) and run the commands:

  sudo ifconfig en0 down
  sudo ifconfig en1 down
  sudo networksetup -setdhcp Wi-Fi
  sudo networksetup -renewdhcp Wi-Fi

  After each command, enter the administrator password (characters will not be displayed).

• 🔍 Checking the adapter status: V Terminal enter networksetup -listallhardwareportsIn the output, find the section Wi-Fi - if there is someone standing next to him (null) or No hardware port found, this indicates a hardware problem.

Make sure Wi-Fi is enabled in the menu|Check Airplane Mode|Refresh Network List (Option+click)|Run Reset Commands in Terminal|Check Adapter Status in NetworkSetup-->

If the problem persists after resetting network services, try creating a new network location:

1. Open System Preferences → Network.
2. In the drop-down menu Location select Change locations....
3. Click +, name the new location (for example, Home 2) and save.
4. Reboot MacBook.

3. Conflicts with router settings: hidden networks, standards, and security

Sometimes MacBook doesn't see Wi-Fi due to incompatibility of router settings with the requirements macOSThis is especially true for networks with hidden SSID, non-standard channels or outdated security protocols.

If your router uses hidden SSID, try temporarily making the network visible or adding it manually:

1. Open System Preferences → Wi-Fi.
2. Click Other networks....
3. Enter the network name (SSID), select the security type and enter the password.
4. Save the settings and try to connect.

⚠️ Attention: Some routers (Zyxel Keenetic, MikroTik) use non-standard settings by default DTIM or Beacon Interval, which may conflict with MacBookIf other devices connect normally, and macOS - No, try resetting the router to factory settings and setting it up again.

4. Reset network settings and reinstall drivers

If basic methods don't help, it's time for more radical measures - resetting network settings and reinstalling Wi-Fi drivers. This method is effective in 60% of cases. MacBook doesn't see networks after the update macOS or reset the system.

Reset network settings:

1. Open Terminal and execute the commands one by one:

   sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
   sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
   sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist

2. Reboot MacBook.
3. After reboot, open System Preferences → Network and set up the connection again.

Reinstalling Wi-Fi drivers (relevant for MacBook with chips Broadcom):

1. Download the latest version Broadcom Wi-Fi drivers from the official website Apple (or through Software update).
2. Open Terminal and run:

   sudo kextunload /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/
   sudo kextload /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/

3. Restart your device.

For MacBook on chips Apple Silicon (M1/M2/M3) may be required reset NVRAM:

1. Turn it off MacBook.
2. Hold the power button for 10 seconds until the loading screen appears.
3. Select Settings → General → Reset NVRAM (on some models this item may be absent).

5. Hardware problems: how to recognize them and what to do

If software methods do not help, the problem may lie in hardwareMost often it is:

• 🔌 Disconnected or damaged antenna cable (relevant for MacBook Pro (2015-2019).
• 🔥 Wi-Fi module overheating (especially on MacBook Air M1 under prolonged load).
• ⚡ Broadcom chip failure (typical for models with Intel-processors).
• 💧 Liquid ingress on the motherboard (even a small amount can cause corrosion of the Wi-Fi module contacts).

How to diagnose a hardware problem:

1. Check the indication: If the Wi-Fi menu displays a message Wi-Fi hardware is not installed, this almost always indicates a physical malfunction.
2. Look in System Report:
   1. Click on the logo Apple in the upper left corner → About this Mac → System Report.
   2. Go to the section Network → Wi-Fi.
   3. If in the line Interface costs Absent or Undefined, this confirms a hardware failure.
3. Check your connection in Windows (if installed via Boot Camp): If Wi-Fi works in Windows, but not in macOS, the problem is software. If it doesn't work anywhere, it's hardware.
