how to find the best channel for wifi mac

You can ensure that youre getting the best Wi-Fi connection possible with the Wireless Diagnostics application on macOS.

Heres how.

Youll see a list of all of the Wireless Access Points in your area.

Each access point is then split into the 2.4ghz range and the 5ghz range.

Although the Scan may tell you which channels are least used in your area, the dirty little secret is that only 3 channels have the best connectivity due to something called Channel Overlap.

Channel overlap is beyond the scope of this article but to keep things simple, the channels that do not suffer from channel overlap are channels 1, 6 and 11.

These are the best channels to chose from when setting your channels in your router.

Youll notice that most access points will be set to one of these three channels but you can still find out the best channel to choose from by seeing which channel is used the least in your area.

To keep things simple, the RSSI is the signal strength of an access point.

Click the RSSI tab so that the listing of RSSIs are in ascending order.

Your personal access point should be listed nearest to the top as its the closest one to your Mac.

If its not, rerun your Scan tool physically seated next to your access point.

This access point is the nearest router to you that can cause you interference.

You do not want your channel number set to the same channel as this one.

For example, if the channel number is a 6, youd want your channel number set to a 1 or 11.

The more devices connected to your router, the more interference.

The absolute best connection to the internet is a wired connection.
