Solving the problem with wi-fi on MacOS

Последние изменения: 09.09.2022

There are situations when everything works correctly on all devices and only on one or two Apple devices there are problems with wi-fi connection (low speed, high ping, disconnection from the wi-fi network). In such cases, you need to recreate the network settings.

How to do it on a computer:

- We need to delete the current settings in order to allow Mac device to automatically recreate the network settings.

  1. Turn off Wi-Fi in the status bar.

  2. Create a backup of the settings just in case. To do this, create a folder on the desktop.

  3. Launch Finder and press Command + Shift + G

  4. Specify the path to the folder /Library/Preferences/SystemConfiguration/

  6. Move all files to a folder on the desktop. This way we have a backup in case that something goes wrong.

  7. The SystemConfiguration folder must be empty after all operations.

  8. Reboot your Mac.

In most cases, this method solves almost any network problem. However, if it does not help, move on to the next method.

We need to change the MTU size - the maximum size of one data packet. In some cases this may help.

  1. Launch System Preferences.

  2. Find the "Network" section.

  3. Select our Wi-Fi connection and select the "Accommodation" section. Editing.
