Network is slow ... Mac wireless acceleration tech you want to try at such times

Let's check the network status

Let's start by looking at what the wireless network is doing. On macOS, you can check the channel to which Wi-Fi is connected, the noise level, etc. by clicking the Wi-Fi icon on the menu bar while holding down the [Option] key.

If the PHY mode is "802.11ac" and the transfer rate is "866Mbps" or higher, you shouldn't have any problems. You can also open "Wireless Diagnosis" from this menu, so if you feel that your Wi-Fi connection is unstable and slow, try diagnosing it. The diagnostic results show the problems found and the solutions, so take action in order.

Also, if you want to check the network speed more quickly, search for "speed test" on Google and use the internet speed test displayed at the top, or use an application such as "Speedtest by Ookla". Is also recommended. The speed of the Internet changes depending on the time of day and the degree of bandwidth congestion, so change the conditions and investigate.

Until macOS Catalina (10.15), I was able to check if the network was normal using a standard application called "Network Utility". For example, using "Ping" to check the response speed of the Internet line, it was possible to easily check the network route to the IP address of the target device.

However, the network utility is obsolete in the current macOS Big Sur, so you have to operate the command from the "Terminal" app to use Ping. If you're new to command operations, it's a good idea to search for something like "Ping" to use a third-party app from the Mac App Store.

In macOS Big Sur, you can register by dragging the [Wi-Fi] item from the control center to the menu bar, and you can display the details of the connected network by holding down the [option] key and clicking. Distributed on the Mac App Store. I measured it with the network speed measurement application "Speedtest by Ookla". Since you can export the measurement history with CSV, let's check it multiple times by changing the day and time zone Since the standard "network utility" has been abolished in macOS Big Sur (left in the figure), commands such as ping and netstat are terminal Must be run from. "Wireless diagnostics" will continue to be available (right)
