To download and install the latest version of macOS Big Sur System Preferencesclick Software updateFinally click Update now..
Try using the 5.5GHz band
If you’re still struggling to solve the problem, try switching to the 5GHz band (if possible). The reason we recommend giving you a chance is to provide more bandwidth compared to the 2.4GHz band. Moreover, it is more efficient.
To start using the 5GHz band with a dual band router, separate the 2.4GHz and 5GHz networks with your router. It would be better to give them different names.
You can set your Mac to participate in 5GHz. To do this System Preferences → Network pane..Then click Wifi Choose Details button. Finally, you have to Drag the 5GHz network to the top.
6. Run Apple Diagnostics
“Apple Diagnostics” can help you find the root of the problem. Therefore, run them in your notebook to find the problem.

macOS comes with a wireless diagnostic utility that can detect common Wi-Fi problems. In addition, this app also helps you monitor your wireless connection for intermittent connection failures. It also notifies you when a connection failure is detected.
- Open Wireless diagnostics On Mac. You can use Spotlight to open it quickly.
- Then click Windows Select a menu to select performance..
- Next, you will see three graphs. Transmission speed, Signal qualityWhen Signal and noise levels..
The network data rate is displayed in Mbps. In most cases, the data rates are consistent. However, if it is substandard, it means something is wrong.
Look at the central graph named Quality, which shows the ratio of signal to noise. If there is a small straight line with small spikes, it means that you have reached the mark. But if not, there is something that gets in the way of the signal.
There is a graph below called Signal. Shows signal strength and measured noise and is displayed as dBM or decibel milliwatts. If you’re wondering what they are, let me tell you that they are a commonly used unit of power for radio signals.
If the signal strength is 60–10dBm and the noise level is less than -75dBm, it’s pretty good. Track the graph to see when the signal is below the expected level.
8. Check your DNS settings
Now that you’ve tried all the options above, let’s take a closer look at your DNS settings. Wondering what that means? Well, let you clear it. This stands for Domain Name System and helps Macs translate domain names such as apple.com into IP addresses. Also, you cannot connect to the site by that name in case the DNS server used by your computer fails.
So how do you know if DNS is working? It’s very easy. Open a web browser and enter the following URL:
This will take you to Apple’s website. If so, your internet connection is working properly and there may be a problem with your domain name.
