    Wireless Diagnostic Utility Mac can detect common Wi-Fi issues

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 into IP addresses.
