Given that some electrical devices (including devices situated in neighboring rooms and homes) and other networks can impact your performance, you might want to keep an eye on this while moving your Mac around. The Performance pane shows you the quality of your Wi-Fi over time. An SNR of 25 or above means you should have good performance. This is called the SNR (Signal to Noise Ratio) and the higher this number is the better your Wi-Fi performance will be. The difference between these numbers is the quality of your network, so if you have an RSSI of -47 and a Noise level of -96 then the difference is 49. Like RSSI this is measured in minus numbers, but a lower number is best, so a Noise level of -46 is better than one of -40.

Neighboring networks, or the usual network interference culprits such as microwaves or some cordless phones, can impact your reception. Noise refers to the amount of wireless noise that may be affecting Wi-Fi reception. Higher numbers are better but because these are rated as minus numbers, it's important to note that an RSSI of -60 is actually much better than an RSSI of -80. The first refers to the strength of the signal between your Mac and your router. The Wi-Fi scan pane offers two metrics to help you determine this: Signal (RSSI, Received Signal Strength Indication) and Noise. You can use the information to determine the strength of your Wi-Fi signal (or use the Performance tab in this window to see how the tool sees your network performance in the Quality section to top left). If you find you are sharing a channel with others nearby, it helps to change the channel on your router to one the other networks aren't using - a clear channel usually improves reception quality. The first thing to check is what channel your network is on in comparison with other networks in your area.

This shows you much information inside: Info, Logging and Performance windows A Frame Capture mode to sniff network traffic and a Wi-Fi Scan mode that captures useful info about your own and other networks in your area. While in Wireless Diagnostics, open the Utilities Window via the Menu bar ( Command-2). When you launch the app, a screen appears to tell you what the tool does and asks you to let it run tests to determine the state of your current Wi-Fi connection these can take a few minutes to complete. In the drop-down menu that appears, select "Open Wireless Diagnostics." The Wi-Fi Diagnostics app is hidden inside / System/Library/CoreServices/Applications, from where you can drag the app icon to make it easily available in your Dock. To access Wi-Fi Diagnostics, Option-click on the Wi-Fi icon in your Menu bar.

Apple's hidden Wi-Fi Diagnostics tool should help you improve Wi-Fi performance.

Ensure the router's antennae are positioned optimally.

Make sure your Wi-Fi router is positioned in a central place in your home or office.

If your Wi-Fi signal is weak, there are a lot of possible causes, and your troubleshooting options are extensive. This is the lowest possible value that will make a connection between the router and computer, but it's too weak to be useful for any online service. This is the lowest value that will deliver acceptable results for most online services. Anything from -30 dBm to -50 dBm is excellent and is often about as high as you can get. This is the maximum signal strength you could achieve, and it probably means you are within a couple feet of the Wi-Fi router. Here are some guidelines for assessing your signal strength: Moreover, a 10 dBm change adds up to ten times more or less strength. In addition, signal strength isn't linear it's logarithmic, which means that every 3 dBm change represents a halving or doubling of the strength of the signal. For example, -80 dBm is a much weaker connection than -30 dBm. In other words, the larger the absolute value, the weaker the network connection. Dave Johnson/Business Insider How to interpret your network's signal strengthĭecibels are expressed as negative numbers, and the closer to zero the number, the stronger the signal.
