![]() ![]() ![]() WiFi Explorer will also highlight the interfering networks, so you can make an informed decision about the channel you want to switch to. For example, if the SNR is lower than 25 dB and the signal strength is below 40%, you might need to decrease the distance to the router. To make the most of your network, you should ensure that the SNR is above 25 dB. ![]() You can fully optimize your Wi-Fi network by using the report WiFi Explorer generates: it determines the signal quality of your wireless connection by monitoring the signal-to-noise ratio (SNR) of the network, which compares the signal strength to its background noise levels. As it scans your location for wireless networks, WiFi Explorer presents its findings in a nice and easy-to-understand user interface. One of these is WiFi Explorer, which is even able to identify networks with a poor signal. This will show the wireless networks, along with the protocol(s) this utility app has detected.įor more advanced information and detailed mapping, there are third party apps that we have found to be more useful. If you hold down the Option key while clicking on the AirPort icon, macOS will share much more info about the wireless network you are connected to.īy selecting “Open Wireless Diagnostics” you will be able to determine common problems with your wireless connection and monitor it for issues, but instead we recommend holding down the Option-Command-4 keys to launch the Scan window. ![]() Use the Mac’s built-in tools to get information about the network. We highly recommend using any of these uncontested channels but, if possible, try switching to the 5GHz frequency, because there are fewer clients using it. There are only three non-overlapping 20MHz wide channels in the 2.4GHz frequency: channels 1, 6 and 11. It’s unlikely that your router is the only one in the area using the 2.4GHz frequency – think neighbors’ routers, baby monitors, Bluetooth devices, cordless phones, and such – and so it’s important to keep in mind that adjacent channels will interfere with each other, therefore causing a poor signal. One of the most common causes of poor Wi-Fi performance is network interference. Mac computers also support these two frequency bands, but older devices such as the iPhone 4, for example, only support the 2.4GHz band. Nowadays, good routers and access points support two frequencies: 2.4GHz and 5GHz. So have a look at the manual before proceeding and make any necessary changes, if required, based on the manufacturer’s recommendations. Since the router is the centerpiece of any Wi-Fi network, it can affect the speed of your internet connection if configured improperly. Assuming that the latter is a given (don’t use a first-generation AirPort Extreme Base Station, for example), then start by testing your internet speed: plug the Ethernet cable directly into your Mac, visit, and click “Go”. If you want web pages to load more quickly, YouTube or Netflix to stream smoother, and faster downloads, then you need to optimize your Wi-Fi connection and ensure you have the best equipment to make that possible. There are a number of wireless network settings that affect the performance of your Wi-Fi connection, some of which may currently make your internet slower than it could be. ![]()
