I don't think so, it is one network, one name sort of deal. The units that are 'satellites' just are duplicators essentially the use the same name as the main Deco to increase coverage over larger 'distances'.

Why would you want individual networks even?

Is there any way to rename networks for individual Deco M5 devices? I've recently been trying to set up VR trackers and due to having 4 networks under the same name, I've been having difficulties getting them to connect. I tried unplugging my Deco devices, but it reduces the quality of the network so much it becomes impossible to do anything.

If you power off  the satellite Deco units, you would only be working with the main Deco, and you might be too far away for a good SSID connection, even with the 2.4Ghz band?

In the Deco app however you can SET which Deco unit the Tracker will always connect too... one in the middle might work for what you want?
