You can change the channels of hubs you’ve already added to your installation. Since adjacent KNets on the same channel can cause mutual interference, changing a hub’s channel may be the best way to ensure reliable communication.
Caution: Before changing a hub’s channel, make sure that all of the KNet’s devices respond to wireless control as expected (instructions below). If they fail to communicate for any reason, they will be left behind when the hub changes channels. The only way to reach them (after troubleshooting whatever error caused them to fail to communicate in the first place) will be to use Recovering an Unresponsive Device in Tech Tool, which can search multiple channels. (See Recovering an Unresponsive Device.)
To change an N4 Hub’s channel, follow these steps:
1. Confirm that the KNet’s devices respond to wireless control. Navigate to Design Studio’s Organization tab.
i. In the My Devices list, expand the Hubs section.
ii. Expand the N4 Hub for which you want to change the channel.
iii. Using Shift+Click, highlight all of the hub’s devices. This should cause all of them to identify.
iv. Confirm that all of the devices identify successfully. There should be a blue box next to the device name/serial that says “Identified.” If any device fails to identify, troubleshoot the device. Do not change the hub’s channel until you can successfully identify the device.
2. Open the installation sidebar. To do so, click the user icon in the top-left corner.
3. In the sidebar, select “Change Network Channel”.
4. In the dialogue box, select the hub and a new channel, then click CHANGE. Pick a channel that is at least two channels away from any adjacent KNets.
