How to fix macOS Sonoma Wi-Fi issues
1. Check your Router
Fixing macOS Sonoma Wi-Fi issues is crucial to ensure a seamless online experience on Apple's latest operating system. First and foremost, a common glitch emerges when routers fail to promptly recognize new devices after upgrading to macOS Sonoma. To tackle this, initiating a simple router restart can work wonders. By giving your router a fresh start, you pave the way for smoother device recognition. Once the router is back online, don't forget to reestablish your Wi-Fi connection on macOS Sonoma.
Diving deeper, delving into router settings becomes pivotal. With the prevailing prevalence of the 5GHz frequency for its high-speed connectivity, it's vital to remember that its coverage range might be more confined compared to the 2.4GHz band. This is where your attention is needed. Take a moment to scrutinize this setting, ensuring it aligns with your connectivity requirements. An effective strategy is to assign the same Wi-Fi name, known as SSID, to both the 5GHz and 2.4GHz networks. The brilliance of this approach lies in macOS Sonoma's ability to intelligently pick the optimal network based on varying conditions and connection distances, in turn minimizing the potential for Wi-Fi issues.
If you need to modify your Wi-Fi SSID, follow these steps using Safari on your Mac or iPhone. Enter either 192.168.1.1 or 192.168.0.1 into the browser's address bar. Use "Admin" or "Administrator" as your username, and the default password is "admin." This login information found printed on the bottom of the router. After logging in, locate the section labeled "Wi-Fi settings" to access and make the desired changes.
2. Flushing DNS Cache
DNS, known as the Domain Name System, plays a pivotal role in linking domain names to the numerical IP addresses used by hosting servers. In the context of macOS Sonoma, the DNS settings are typically synchronized with those of the router. This alignment ensures that when you input a website's URL, the system can seamlessly translate it into the necessary IP address, enabling effective communication with the server.
Nevertheless, this harmonization of DNS settings can sometimes introduce challenges to internet connectivity, even if your Wi-Fi connection to the router seems stable. These discrepancies might lead to difficulties in accessing websites or online services. Thankfully, a straightforward solution exists in the form of clearing the DNS cache. This process entails removing stored DNS data that might be causing conflicts. To perform this task, the Terminal application on macOS Sonoma comes into play.
To initiate the procedure, the first step involves accessing the Terminal, which can be achieved through a Spotlight search or by locating it in the Applications>Utilities folder. Within the Terminal, executing the command mandates administrative privileges, as indicated by 'sudo.' Therefore, inputting your macOS password becomes essential to authorize the execution of the command.
sudo killall -HUP mDNSResponder
By grasping the significance of DNS in upholding internet connectivity and adhering to these outlined steps, achieving a smoother online experience on macOS Sonoma becomes readily attainable.
3. Change DNS on macOS
If you want to enhance your internet experience, consider switching from your internet service provider's default DNS to better alternatives like Google or Cloudflare. Google offers the DNS addresses 188.8.131.52 and 184.108.40.206, while Cloudflare provides 220.127.116.11 and 18.104.22.168.
Changing DNS settings on macOS Sonoma is simple. Just follow these steps:
- Begin by accessing System Settings on your macOS Sonoma and navigate to the Wi-Fi section.
- Choose your Wi-Fi network's name and click the adjacent 'Details' button.
- Click the DNS icon and then press the '+' button to add DNS server IP addresses.
- You can add the DNS IP addresses sequentially, starting with Google's 22.214.171.124. Even using just one DNS IP, Google's DNS works effectively.
- If necessary, you can add a second DNS IP, like 126.96.36.199. After saving your changes, double-check the internet connection on your macOS Sonoma to ensure everything is functioning smoothly.
4. Reset Network Settings
Mac Users are often looking for the 'Reset Network Settings' feature similar to what's available on iPhones, as it proves helpful in addressing Wi-Fi-related problems. However, as of now, macOS Sonoma doesn't provide support for this feature. Instead, the process of resetting network settings on macOS Sonoma needs to be done manually. Network configurations are stored within files bearing the .plist file extension. To rectify Wi-Fi issues on macOS Sonoma, we must delete these files, prompting the system to generate new ones with default settings.
To manually reset network settings, follow these steps:
- Commence by disabling Wi-Fi on your macOS Sonoma.
- Proceed to open Finder and navigate to Go > Go to Folder.
Within the prompted field, copy and paste the subsequent path: /Library/Preferences/SystemConfiguration.
Subsequently, locate the files possessing the .plist extension and remove them, including those residing in the macOS Trash.
After removing these files, proceed to restart macOS Sonoma. Once the system has rebooted, attempt to reconnect to your Wi-Fi network. You'll notice that your internet connection is now up and running smoothly on your macOS.
5. Connect to VPN on macOS
To effectively tackle DNS-related or security issues while using the internet, which can sometimes result in Wi-Fi problems on macOS Sonoma, the optimal solution is the utilization of a VPN. A VPN, or Virtual Private Network, allows us to surf the web and download data from the internet using the IP address of the VPN, effectively concealing our actual IP.
While numerous VPN options exist, one standout choice for reliability and stability is NordVPN. Boasting an extensive network of global servers, NordVPN offers the promise of swift and dependable connections. It goes beyond by offering features such as Malware Protection and Data Breach Scanner, adding an extra layer of defense against risky websites and potential data threats. Moreover, with the elevated "Complete" subscription, users enjoy the added perk of 1TB of complimentary Cloud Storage as part of the 1-year plan.
