How to Fix macOS Sonoma WiFi not working

Welcome to this friendly guide on how to fix the macOS Sonoma WiFi not working issue. In this blog post, we will provide you with a step-by-step outline to help you troubleshoot and resolve connectivity problems on your Mac. WiFi issues can be frustrating, but with the right approach, you can get your internet connection up and running smoothly again. So, let's get started!

Determine the Extent of the Problem:

The first step in addressing the WiFi issue is to determine the extent of the problem. Start by restarting the affected application that is not connecting to the internet. If the problem persists, reboot your Mac. Sometimes, a simple restart can resolve minor connectivity issues. Additionally, check other devices on the same network to see if they are experiencing WiFi problems. This will help you determine if the issue is isolated to your Mac or if it is affecting other devices as well.

2. Addressing the Problem:

a) Restart Your Router:

One of the most common solutions for WiFi connectivity issues is to restart your router. To do this, power off your router and wait for a few seconds. Then, power it back on and allow it to fully restart. This simple step can often resolve temporary glitches in the router's connection.

b) Flush the DNS Cache:

Another step you can take to fix the WiFi issue is to flush the DNS cache on your Mac. To do this, open Terminal (Applications > Utilities > Terminal) and type "sudo killall -HUP mDNSResponder" without the quotes. Press Enter and enter your administrator password when prompted. This will clear the DNS cache and may help resolve any DNS-related issues.

c) Change DNS Server:

Sometimes, changing the DNS server can improve WiFi connectivity. To change the DNS server on your Mac, go to System Preferences > Network > Wi-Fi > Advanced. Select the "DNS" tab and remove any existing DNS servers. Then, click the "+" button to add new DNS servers. You can use popular DNS servers like Google DNS: 8.8.8.8 and 8.8.4.4. Click OK and Apply to save the changes.

d) Renew DHCP Lease:

Renewing the DHCP lease can also help resolve WiFi connectivity problems. To do this, go to System Preferences > Network > Wi-Fi > Advanced. Select the "TCP/IP" tab and click the "Renew DHCP Lease" or "Renew DHCP Lease Now" button. This will refresh your Mac's IP address and network settings.

e) Delete and Reconnect to a Wi-Fi Network:

If you are experiencing issues with a specific Wi-Fi network, you can try deleting and reconnecting to it. Go to System Preferences > Network > Wi-Fi and select the Wi-Fi network causing problems from the list. Click the "-" button below the list to remove it. Then, reconnect to the network by selecting it again and entering the password if required.

f) Turn Off the Firewall:

In some cases, the firewall on your Mac may interfere with the WiFi connection. To check if the firewall is causing the issue, go to System Preferences > Security & Privacy > Firewall. Click the lock icon and enter your administrator password. Temporarily disable the firewall and check if it resolves the WiFi issue. If it does, you can configure the firewall settings to allow the necessary connections.

g) Clear Out Old Wi-Fi Networks:

Over time, your Mac may accumulate a list of unnecessary or unused Wi-Fi networks, which can cause connectivity issues. To clear out these old networks, go to System Preferences > Network > Wi-Fi. Click "Advanced" and select the "Wi-Fi" tab. From there, you can remove any unnecessary networks from the list.

Confirm Issue Resolution:

After implementing the troubleshooting steps, it is important to confirm if the WiFi issue has been resolved. Open a website or perform an internet-related task to check if you now have a stable connection. If you are able to browse the internet without any issues, congratulations! You have successfully fixed the macOS Sonoma WiFi not working problem.
