  • The best channel to use will vary depending on the environment.
  • If you are experiencing interference from other Wi-Fi networks, you can try changing the channel to one that is less congested.
  • You can also use a Wi-Fi analyzer app to view the channels that are in use and choose the one with the least amount of interference.

Here are some additional things to keep in mind when using a different wireless channel on MacBook:

  • If you are not sure which channel to use, you can consult with your Wi-Fi network administrator.
  • Changing the channel may not always improve your Wi-Fi connection.

Updating to the latest router firmware can resolve incompatibility issues causing MacBook Wi-Fi problems.

To update your router’s firmware, you can follow these steps:

  2. Find the firmware update section. This is usually located in the Administration or System menu.
  3. Download the latest firmware update from the router manufacturer’s website.
  4. Upload the firmware update to your router. This is usually done by clicking on a Browse button and selecting the firmware file that you downloaded.
  5. Restart your router. This will complete the firmware update process.

Here are some things to keep in mind when updating your router’s firmware:
