MacBook won't connect to Wi-Fi? How to fix it

⚡️Fast fix

• Restart your MacBook. It may be a temporary glitch.
• Toggle the Wi-Fi setting. Turning Wi-Fi off and on forces your computer to search for a connection.
• Reboot your router. Unplug your router and wait 30 seconds before plugging it back in.

You power up your MacBook®, ready to start a busy workday. But when you open the Safari® browser and enter a web address, nothing happens. Your device isn't connected to the internet. That's strange—it was working fine yesterday. How can you get back online?

Asurion Experts keep your favorite devices running smoothly. Whether your Mac® isn't updating or you need help choosing the best Wi-Fi router for your home, we can help you with your tech. Here's what to do when your MacBook won't connect to Wi-Fi.

Refresh your local network settings

If your Wi-Fi doesn't work after trying the quick fixes, there may be a glitch in your network settings. These troubleshooting tricks explain how to reset Wi-Fi settings on a MacBook.

Forget and rejoin your network

Forcing your laptop to wipe its memory of a specific connection often clears authentication loops. Make sure you know your password before executing these steps:

1. Click the Apple menu icon in the top-left corner and open System Settings.
2. Select Wi-Fi from the left sidebar.
3. Find your home network name, click the Details button next to it, and select Forget This Network.
4. To reconnect, click the Wi-Fi icon in your top menu bar, select your network name, type in your password, and click Join.

Reassign the DHCP lease

Some server networks provide temporary Internet Protocol (IP) addresses under a Dynamic Host Configuration Protocol (DHCP) lease. This is common in businesses, where too many connected devices can clog up the network. Some home networks may use a DHCP lease, too.

You can check whether your device is using DHCP and request a lease renewal by taking these steps:

1. Click the Apple menu icon and open System Settings.
2. Select Network from the left sidebar.
3. Click on Wi-Fi or the specific network connection profile you want to refresh.
4. Click Details > select TCP/IP from the menu, and click Renew DHCP Lease.
5. Click OK to confirm the update.

Check for software and system conflicts

If your laptop won't connect to Wi-Fi after refreshing the network, there may be a conflict between your device and its software. Try each of these troubleshooting alternatives to see if they resolve the issue.

Clear out VPN interference

If you use a virtual private network (VPN) when surfing the web, turn it off. Your Wi-Fi network's settings may not be configured to work with VPN, which can cause the connection to drop.

You can also try changing your VPN location to another city. Sometimes, VPNs get overloaded with users, and moving to another location can fix connection issues.

Verify device time and date

An inaccurate system clock will cause your router and web browsers to reject data handshakes because they can't validate secure web certificates.

1. Open System Settings > General > Date & Time.
2. Ensure the toggle for Set time and date automatically is turned on.If it's greyed out, click the lock icon to authorize the change.

Update your system software

Apple® releases frequent system software updates to fix bugs and resolve underlying network conflicts. If you haven't updated your machine in a while, a patch might be exactly what you need to get your Wi-Fi working again.

1. Click the Apple menu in the top-left corner and select System Settings.
2. Click General in the left sidebar, then select Software Update on the right.
3. If an update is available, click Update Now (or Upgrade Now).

Tip: If your Wi-Fi is completely down and you can't download the update, try plugging an Ethernet cable into your Mac using a USB-C adapter, or temporarily plug your iPhone into your Mac with a cable to share its data connection via USB Tethering (found in your iPhone settings under Personal Hotspot).

Reset the SMC and NVRAM on Intel Macs

If you have an older, Intel-based Mac (from 2020 or earlier), resetting its System Management Controller (SMC) and Non-Volatile Random Access Memory (NVRAM) can clear up stubborn hardware conflicts that lock up your Wi-Fi card.

How to reset the SMC on an Intel MacBook:

1. Shut your MacBook down completely and ensure it is plugged into a power source.
2. On your keyboard, press and hold the Shift + Control + Option keys on the left side, then press and hold the Power button as well.
3. Keep all four keys held down for 10 seconds, then release them all at the same time.
4. Press the Power button normally to turn your MacBook back on.

How to reset the NVRAM on an Intel MacBook:

1. Shut your MacBook down completely.
2. Press the Power button, and immediately press and hold the Command + Option + P + R keys together before the screen lights up.
3. Keep holding these keys for about 20 seconds (you may hear the Mac startup chime ring a second time, or see the Apple logo flash twice).
4. Release the keys and let the MacBook finish booting normally.

(Note: If you have a newer MacBook with Apple Silicon—M1, M2, M3, M4, or newer—you do not need to do this. Your hardware handles these system variable purges automatically during a standard restart).
