Hi, welcome to the community.

The SSID " zEQQxxx" is a hidden network by default, and it’s designed for 6 GHz backhaul used along with other bands. However, once activating the 6 Ghz primary Wi-Fi on the Deco App, this SSID will become visible. The reason for broadcasting this SSID is to ensure compatibility with certain cellphones or NICs that support the 6 GHz band, such as the Samsung S21. These devices may struggle to detect Deco's wireless signals if the zEQQ SSID remains hidden. 

Rest assured, your network security is guaranteed. Even though this SSID is visible, it is encrypted by default, and client devices are prohibited from connecting to it.

Moreover, We are currently evaluating to optimize this mechanism on the 6GHz-supported Deco devices and will consider the option of hiding this zEQQ SSID in future firmware updates. 

Thank you very much and best regards.
