INTERFERENCE AND CHANNEL SELECTION

Both the Wi-Fi and Wifly radios operate in the 2.4GHz band. Many other devices including Wi-Fi

routers, Bluetooth devices, and wireless audio also use this band, so the bridge will most likely

always be competing for air space no matter where you are. The 2.4GHz Wi-Fi band is divided into

14 channels. Wi-Fi in the U.S. and Canada uses channels 1-11, and in Europe channels 12 and 13

are also available. For the best connection between your Wi-Fi tablet, phone, or laptop, and the

bridge when it’s in AP mode, it’s important to select the best available Wi-Fi channel. (Note that

when using an external network when the bridge is configured in station mode, it will join on the

channel that’s already established by that network.) There are apps available that can use the radio

on your wireless device to scan for the least used channel in your location. It is highly recommended

that you do this at each location and then set the bridge to that channel. Remember that most

bridge settings don’t take effect until after you reset.

Try to keep the bridge within 50 feet of your tablet or laptop and in direct line of sight when in AP

mode. When using an external network, distance and signal strength will depend on the location of

the network’s router. The human body will block the signal so the higher you can locate the bridge

the better. If you are within a few feet of the bridge, turn Bluetooth off on any nearby device such as

your phone or smart watch. The range of the Wifly radio is much greater so Wifly equipped lights can

be much farther away. If not using Wifly turn it off from the bridge settings. If in use, set the channel

at least several steps away from the bridge Wi-Fi channel. The best channels to use for Wifly are

channels 4 and 9. These two channels fall into a gap between Wi-Fi channels 1, 6 and 11. Wifly

counts channels from 0-14 as can be seen in the picture.

The illustration below shows the center frequencies for Wi-Fi (top) and Wifly (bottom, also referred to

as Snap). If you use Wi-Fi channels 1, 6 or 11, Wifly channels 4 and 9 should not interfere.
