I recently did this and saw a huge improvement in network reliability my connection used to randomly disconnect for several seconds a few times a day, now the failure rate is close to once a week.
If you are experiencing intermittent service with your Wi-Fi, check this screen and set your router to use a different channel for its communications, picking the “best” one for the 2.4GHz and 5GHz bands as suggested by the application. The left-hand side of the Scan window suggests the best ‘clear’ channels in the area for both 2.4 GHz and 5GHz. Having too many Wi-Fi stations communicating on the same band/channel can also cause crippling interference problems which results in unreliable internet and connections that drop out. When you think about Wi-Fi, normally it’s in the context of interference from interior walls. Scan allows you to see the channels on which these other Wi-Fi routers are operating. This is particularly important for people who live in congested areas, like a block of flats, where many Wi-Fi stations are setup in close proximity. Likely the most useful window, Scan relays information about your network and the other networks in the vicinity. A more approachable version of the same information can be found in other views. Afterwards, export the log and extract the best and worst case readings. If you wanted to test RSSI readings across the house, you could enable logging and then take your MacBook for a walk. One nice thing it does do is keep a periodic history of Wi-Fi connection quality, assuming you can read through the extraneous lines. These logs are not that simple to decipher for humans, however, and are very noisy. The Logs tab is perhaps the most inscrutable window in Wireless Diagnostics as its entire purpose is to record relevant network process activity to a system log file which can then be inspected in the Console app.

The Wireless Diagnostics panels update with the new live values if the Tx rate changes. What’s slightly confusing is that the Tx rate is not constant for a particular router: it will vary as the system adapts to wireless conditions with the mentality that a slow, stable, connection is better than a faster, unreliable, one.

You may need to change settings or upgrade your hardware to a new router (suggestions below) to take full advantage of your ISP’s speed. As 2.4GHz usually provides longer range signals, a common error for Wi-Fi performance is to simply move closer to the unit so the laptop can pickup the (faster) 5GHz link.Īnother interesting data point to check is the Tx rate which states the maximum possible transfer speed for the current connection. If you have super-fast fiber broadband but your quoted Tx rate is only 78 Mbps, don’t be disappointed when your maximum Internet speed is also capped at 78. If you were expecting to see 5GHz listed but don’t, first check your router configuration and then try moving closer to the base station.
For example, if you are running a dual-band Wi-Fi network like the AirPort Extreme, it’s worth checking that you are actually running on the GHz band that you expect. This screen is useful for quick diagnosis of the most obvious problems. The current noise and RSSI levels are also displayed here, more on that later.

This includes quick access to information like the MAC address of the hardware, the Wi-Fi mode, operating band and channel. The Info tab is a simple table panel that displays information relating to the wireless connection. Access these other views from the Window menu bar item.

As a standalone self-help tool, however, the assistant is not very useful in my opinion. The more interesting data for individuals can be found on different windows of Wireless Diagnostics. At the end of the process, the assistant generates a report that can be sent to Apple Support for further assistance. The first screen is the Assistant, the app’s automatic step-by-step diagnostics wizard for detecting common network problems.

Although the app contains a lot of useful information, it isn’t intuitively clear what you are supposed to do with it.įrustrated by bad WiFi on Mac OS X? This guide may help you get better WiFi on your computer.įollow along below for a walkthrough of all the screens in Wireless Diagnostics that can help you analyze your Wi-Fi network and find any weak spots. It can be daunting to see so many stats at once but in reality you are only interested in a couple of numbers. Open the app by option-clicking on the Wi-Fi indicator in the menu bar and select ‘Open Wireless Diagnostics …’. Apple ships a little-known utility app that helps you analyze and diagnose your Wi-Fi connection, called Wireless Diagnostics.
