Wi-Fi connectivity is one of the most essential features of modern computing, and when it doesn’t work as expected, it can be frustrating and disrupt our workflow. If your Mac isn’t connecting to Wi-Fi, don’t panic! This article will guide you through a series of troubleshooting steps to help you identify and fix the issue.
Step 1: Check Your Wi-Fi Network and Settings
Before we dive into the more advanced troubleshooting steps, let’s start with the basics. Ensure that your Wi-Fi network is working correctly and that your Mac is configured to connect to it.
Check Your Wi-Fi Network
- Restart your router: This might sound simple, but restarting your router can often resolve connectivity issues. Unplug it from the power source, wait for 30 seconds, and plug it back in.
- Check your internet service provider’s (ISP) status page: Visit your ISP’s website or social media page to see if there are any reported outages or maintenance in your area.
- Check your Wi-Fi network name and password: Ensure that you’re using the correct network name (SSID) and password. If you’re unsure, check with your ISP or the person who set up the network.
Check Your Mac’s Wi-Fi Settings
- Click the Wi-Fi icon in the top right corner of your screen and select “Open Network Preferences.”
- Ensure that Wi-Fi is enabled and that you’re connected to the correct network.
- Check that your Mac is set to obtain an IP address automatically. To do this, click “Advanced” and then select “TCP/IP.” Make sure the “Configure IPv4” dropdown is set to “Using DHCP.”
Step 2: Restart Your Mac and Wi-Fi Network
Sometimes, a simple restart can resolve connectivity issues.
Restart Your Mac
- Click the Apple menu and select “Restart.”
- Wait for your Mac to shut down and then start up again.
Restart Your Wi-Fi Network
- Unplug your router from the power source and wait for 30 seconds.

Run a Virus Scan
- Open your antivirus software and run a full scan of your Mac.
- Follow the software’s instructions to remove any detected malware or viruses.
Step 8: Reset Your Mac’s Network Settings
If all else fails, you can try resetting your Mac’s network settings. This will remove all network settings and return them to their default values.
Reset Your Mac’s Network Settings
- Click the Apple menu and select “System Preferences.”
- Click “Network.”
- Click “Advanced.”
- Click “TCP/IP.”
- Click “Renew DHCP Lease.”
- Click “OK” and then try connecting to the Wi-Fi network again.
Additional Troubleshooting Steps
If none of the above steps resolve the issue, you can try the following additional troubleshooting steps:
Use a Wi-Fi Analyzer App
- Download a Wi-Fi analyzer app, such as Wi-Fi Analyzer or WiFi Scanner, to check for channel overlap and interference.
- Use the app to identify the best channel for your Wi-Fi network and switch to it.
Check for Physical Obstructions
- Physical obstructions, such as walls and furniture, can block your Wi-Fi signal. Try moving your router to a more central location or removing any obstructions.
Check Your Mac’s Wi-Fi Card
- If none of the above steps resolve the issue, it’s possible that there’s a problem with your Mac’s Wi-Fi card. Try resetting the System Management Controller (SMC) or seeking professional help from an Apple authorized service provider.
By following these troubleshooting steps, you should be able to identify and fix the issue preventing your Mac from connecting to Wi-Fi. Remember to always restart your Mac and Wi-Fi network before trying more advanced troubleshooting steps. If the issue persists, you may want to consider seeking professional help from an Apple authorized service provider or visiting an Apple Store for further assistance.

Why won’t my Mac connect to Wi-Fi?
Your Mac may not be connecting to Wi-Fi due to a variety of reasons. It could be an issue with your router, your internet service provider, or even a problem with your Mac’s Wi-Fi settings. Try restarting your router and modem to see if that resolves the issue. If that doesn’t work, try resetting your Mac’s System Management Controller (SMC) and Network Daemons.
Additionally, ensure that your Wi-Fi is enabled and you’re in range of the router. Sometimes, a simple reboot can solve the problem. If you’re still having trouble, try deleting your Wi-Fi preferences and then re-adding your network. You can do this by going to System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease.
How do I reset my Mac’s System Management Controller (SMC) and Network Daemons?
Resetting your Mac’s SMC and Network Daemons can often resolve Wi-Fi connectivity issues. To reset the SMC, shut down your Mac, locate the following keys: power, Command+Option+Shift+Power, or Power+Control+Shift+Power (depending on your Mac model), and press them simultaneously. Hold them down for 10 seconds, then release. Wait 5 seconds, then press the power button to turn on your Mac.
To reset the Network Daemons, go to System Preferences > Network, then select your network connection from the left-hand menu. Click the “Advanced” button, then click the “TCP/IP” tab. Click the “Renew DHCP Lease” button, then click “OK” to save your changes. Your Mac will now reconnect to your network.
What do I do if I’ve forgotten my Wi-Fi password?
If you’ve forgotten your Wi-Fi password, you can try to recover it using your router’s settings. Typically, you can do this by typing the router’s IP address into a web browser, then logging in with the router’s admin credentials. Once logged in, look for the Wi-Fi settings section, where you should be able to find your password.
Alternatively, if you have access to another device that’s connected to your network, you can try to find the Wi-Fi password on that device. On a Mac, go to Keychain Access > System > Passwords, then search for your network’s name. You should see an entry for your network, which will display your Wi-Fi password when you click “Show password”.
Can I use an Ethernet cable to connect to the internet?
Yes, you can use an Ethernet cable to connect to the internet if you’re having trouble with your Wi-Fi connection. An Ethernet connection is a wired connection that uses a physical cable to connect your Mac to your router or modem. This can be a good solution if you’re having trouble with your Wi-Fi signal or if you need a more stable connection.
To use an Ethernet cable, simply plug one end into your Mac’s Ethernet port and the other end into your router or modem. Make sure your Mac is configured to use the Ethernet connection by going to System Preferences > Network, then selecting “Ethernet” from the left-hand menu.
What if I’m still having trouble connecting to Wi-Fi?
If you’re still having trouble connecting to Wi-Fi, try moving your Mac closer to your router to see if that improves the signal strength. You can also try using a Wi-Fi analyzer app to see if there are any channel conflicts or other issues that might be affecting your connection.
Another option is to reset your Mac’s network settings by going to System Preferences > Network, then clicking the “Advanced” button. Click the “TCP/IP” tab, then click the “Renew DHCP Lease” button. Click “OK” to save your changes, then try reconnecting to your network.
How do I delete my Wi-Fi preferences?
To delete your Wi-Fi preferences, go to System Preferences > Network, then click the “Advanced” button. Click the “TCP/IP” tab, then click the “Renew DHCP Lease” button. Next, click the “Wi-Fi” tab, then click the “minus” button next to your network’s name. This will remove your network from the list of preferred networks.
Once you’ve deleted your Wi-Fi preferences, you’ll need to re-add your network by clicking the “plus” button and selecting your network from the list. Enter your password and other network settings as needed, then click “Join” to reconnect to your network.
Will restarting my router fix the problem?
Yes, restarting your router is often a simple and effective way to resolve Wi-Fi connectivity issues. This is because routers can sometimes become overwhelmed or experience technical difficulties, which can cause problems with your Wi-Fi connection.
To restart your router, simply unplug it from the power outlet, wait for 30 seconds, then plug it back in. This will allow the router to reboot and refresh its settings. Once it’s back online, try reconnecting to your network to see if that resolves the issue.
