Potential Risks

However, be cautious. Sometimes, new updates can introduce new issues. For instance, some M1 and M2 Mac users have reported WiFi connectivity issues after updating their macOS. Therefore, it’s a good idea to read the update notes and user feedback before proceeding.

2. Contacting Your Service Provider

So, you’ve tried every trick in the book, but your MacBook still won’t connect to WiFi. Now, it’s time to consider contacting your service provider. Let’s delve into when and how to take this step.

When to Contact Your Service Provider

  1. Persistent Issues Across Multiple Networks
    • If your MacBook struggles to connect to multiple WiFi networks, it’s a red flag.
    • Solution: This could indicate a hardware issue that your service provider needs to address.
  2. After Exhausting All Troubleshooting Steps
    • You’ve restarted your MacBook, updated macOS, and even reset network settings.
    • Solution: If the issue persists, it’s time to make that call.
  3. Network-Specific Problems
    • Sometimes, the issue might be with the network itself.
    • Solution: If other devices can connect but your MacBook can’t, your service provider can help.

How to Contact Your Service Provider

  1. Locate Contact Information
    • Usually, you’ll find the customer service number on your bill or the provider’s website.
    • Solution: Keep this information handy for quick access.
  2. Be Prepared with Details

    • Solution: Follow their advanced troubleshooting steps carefully.
  3. Technician Visit
    • In some cases, they might schedule a technician for an in-person visit.
    • Solution: Make sure to be available at the scheduled time.

3. Restarting Your Router

So, you’ve tried the basics and even updated your macOS, but you’re still facing WiFi issues. What’s next? Well, restarting your router might just be the solution you need. Let’s delve into how to do this effectively.

Why Restart Your Router?

Firstly, routers can sometimes fail to establish a stable connection. A simple restart often clears out minor issues and refreshes the router’s settings.

How to Properly Restart Your Router

  1. Unplug the Router
    • Locate the power cable connected to your router.
    • Solution: Unplug the router from the power source.
  2. Wait for a Few Minutes
    • Patience is key here. Wait for about 2-5 minutes.
    • Solution: This allows the router to fully shut down and clear its cache.
  3. Plug It Back In
    • After waiting, it’s time to plug the router back in.
    • Solution: Reconnect the power cable to the router.
  4. Wait for Router to Fully Restart
    • The router will take a few minutes to fully restart.
    • Solution: Wait until all the lights on the router are stable.
  5. Reconnect Your MacBook
    • Now, try connecting your MacBook to the WiFi network.
    • Solution: If successful, you’ve resolved the issue.

Advanced Router Settings

However, if the issue persists, you might want to delve into advanced router settings. For instance, you could change the WiFi channel if you suspect interference from other networks.

What If Restarting Doesn’t Work?

Sometimes, a simple restart won’t cut it. In such cases, you may need to reset your router to factory settings. But be cautious; this will erase all your custom settings.

4. Changing Router Channels

Alright, so you’ve tried almost everything, but your MacBook still refuses to connect to WiFi. What’s left? Changing your router’s channel could be the game-changer you need. Let’s dive into this advanced troubleshooting step.

Why Change Router Channels?

Firstly, WiFi channels can get crowded, especially in densely populated areas. This congestion can lead to connectivity issues. Therefore, switching to a less crowded channel can improve your WiFi performance.

How to Change Router Channels

  1. Access Router Settings
    • Open a web browser and enter your router’s IP address.
    • Solution: Log in using your router’s username and password.
  2. Navigate to Wireless Settings
    • Once logged in, find the wireless settings section.
    • Solution: This is where you’ll find options to change the channel.
  3. Select a New Channel
    • Channels usually range from 1 to 11 for 2.4GHz and 36 to 165 for 5GHz.
    • Solution: Choose a channel that is less crowded.
  4. Save and Apply Changes
    • After selecting a new channel, save the settings.
    • Solution: Your router will likely restart to apply the new settings.
  5. Test the Connection
    • Once the router restarts, reconnect your MacBook.
    • Solution: Check if the WiFi connectivity has improved.

What to Consider When Choosing a Channel

However, not all channels are created equal. Some might be crowded, while others are less so. Use a WiFi analyzer tool to identify the best channel for your network.

Risks and Precautions

Be cautious when changing router settings. Incorrect configurations can disrupt your network. Always back up your current settings before making changes.

5. Renewing DHCP Lease

You’ve restarted your router, changed channels, and even updated your macOS. Yet, your MacBook still won’t connect to WiFi. Frustrating, right? Well, renewing your DHCP lease might be the next step to consider. Let’s explore how to do it.

Why Renew DHCP Lease?

Firstly, what is DHCP? It stands for Dynamic Host Configuration Protocol. It’s what assigns your MacBook an IP address. Sometimes, renewing this IP address can resolve connectivity issues. Especially in crowded networks or when the DHCP lease time is short.

How to Renew DHCP Lease

  1. Navigate to System Settings
    • Click the Apple menu and go to System Settings.
    • Solution: Then click on Network in the sidebar.
  2. Select Your Network
    • You’ll see a list of network services on the right.
    • Solution: Click the one that needs a renewed IP address.
  3. Go to TCP/IP Settings
    • Next, click on the “Details” button.
    • Solution: Then click on TCP/IP.
  4. Click Renew
    • You’ll see an option to “Renew DHCP Lease.”
    • Solution: Click it and then click OK.

What Happens Next?

After renewing the DHCP lease, your MacBook will request a new IP address. This can often resolve minor connectivity issues. However, if the problem persists, you may need to contact your service provider.

Risks and Precautions

Be cautious. Renewing a DHCP lease will disconnect you temporarily from the network. Make sure you’re not in the middle of something important online.

6. Changing DNS Settings

Still struggling with WiFi connectivity on your MacBook? Don’t worry; there’s another advanced step you can try—changing your DNS settings. Let’s dive into how to do this effectively.

Why Change DNS Settings?

Firstly, DNS stands for Domain Name System. It translates website names into IP addresses. Sometimes, the default DNS servers provided by your ISP aren’t the fastest or most reliable. Changing them can improve your browsing speed and resolve connectivity issues.

How to Change DNS Settings

  1. Access System Preferences
    • Click the Apple menu and select System Preferences.
    • Solution: Then click on Network to open network settings.
  2. Choose Your Network
    • A list of network services will appear on the right.
    • Solution: Click on the network you’re connected to, like “Wi-Fi” or “Ethernet.”
  3. Navigate to DNS Settings
    • After selecting your network, click on “Advanced.”
    • Solution: Then click on the “DNS” tab.
  4. Modify DNS Servers
    • You’ll see a list labeled “DNS Servers.”
    • Solution: Click the “+” button below the list and enter a new DNS address.
  5. Save and Apply
    • After entering the new DNS addresses, click “OK.”
    • Solution: Finally, click “Apply” to save the changes.

What to Consider When Changing DNS

However, not all DNS servers are equally fast or secure. You can use Google’s DNS ( and or OpenDNS as alternatives. Some people even use DNS benchmarking tools to find the fastest servers.

Risks and Precautions

Be cautious when changing DNS settings. Incorrect configurations can disrupt your network. Always note down your current settings before making any changes.

7. Forgetting and Reconnecting to the Network

You’ve tried almost every trick in the book, but your MacBook still won’t connect to WiFi. What now? Well, sometimes, the solution is as simple as forgetting and reconnecting to the network. Let’s explore this often-overlooked step.

    • Solution: Enter the password to reconnect.

8. Using Diagnostic Tools

So, you’ve tried all the advanced troubleshooting steps, but your MacBook’s WiFi issues persist. What’s next? Well, it’s time to bring out the big guns—diagnostic tools. Let’s dive into how to use these tools effectively.

Why Use Diagnostic Tools?

Firstly, diagnostic tools can provide valuable insights into your network’s performance. They can identify issues that standard troubleshooting steps might miss.

How to Use Diagnostic Tools
