The data isn't interfering, however the channel is a little contended. By default the channels used are typically either channel 6 or channel 11.Īs shown in the simplified diagram below, three routers are all using channel 6. As Wi-Fi data is digital, many different devices can communicate successfully on the same channel. Understanding this information is helpful when diagnosing problems with Wi-Fi signals in areas where there are a large number of Wi-Fi networks.Įvery Wi-Fi network transmits and receives data on a certain frequency, or channel. The absolute "best" connection to the internet is a wired connection.This article describes how the different wireless channels are used and how they interact with each other. The more devices connected to your router, the more interference. Even though you can try to limit the amount of interference in your area, the greatest contributor to Wi-Fi connection issues is the number of devices connected to a single access point.

Wi-Fi is inherently made to be "interfered" with. Wait for your Airport Base Station to reboot and you're all set! Wi-Fi will never be the "Best". Set up your 2.4ghz Channel in your Airport Base StationĬlick the dropdown list next to 2.4 GHz Channel and select the channel you discerned by using the Scan Tool. If there are many nearby access points, you'll have to best guess the channel number that is least used and least adjacent to you and set your own channel number to that least used and least adjacent channel. For example, if the channel number is a 6, you'd want your channel number set to a 1 or 11. You do not want your channel number set to the same channel as this one. This access point is the nearest router to you that can cause you interference.

Look at the first 2.4GHz access point listed below your own in the RSSI list.

If it's not, rerun your Scan tool physically seated next to your access point. Your personal access point should be listed nearest to the top as it's the closest one to your Mac. Click the RSSI tab so that the listing of RSSI's are in ascending order. To keep things simple, the RSSI is the signal strength of an access point.

In your Wireless Diagnostics Scan Tool, you'll notice a heading called RSSI.

You'll 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. These are the best channels to chose from when setting your channels in your router. 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. 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". The 2.4GHz Wi-Fi range is a bit more complicated. Wait for your Airport Base Station to reboot and you're all set! The 2.4 GHz range. If prompted for a password, enter your Base Station password.Ĭlick the dropdown list next to 5 GHz Channel and select the channel as suggested by the Scan tool.

Here's how to do it in your Airport Base Station.Ĭlick Edit. If you have a 5GHz Wi-Fi network, you can take the value from Best 5 GHz at face value and set one of the suggested channels in your Wi-Fi router and be done. (2.4ghz is better for penetrating walls, but is more easily interfered with whilst 5ghz has less penetration but has a more stable connection as it is interfered with by fewer devices). Each access point is then split into the 2.4ghz range and the 5ghz range. Under Summary, you'll see the total number of access points. You can click Scan Now to get a fresh "look" at all of the access points if yours isn't listed. You'll see a list of all of the Wireless Access Points in your area. A "Wireless Diagnostics" window will open.

Hold the option key on your keyboard and click on the Wi-Fi network icon in your Title Bar.Ĭlick Open Wireless Diagnostics.
