Mystery BROADCOM_GUEST WiFi Networks

Hello.  My Comcast Business Router is a Technicolor CGA4131.  I have Gigabit service.  In addition to the usual 2.4 and 5GHz networks this router broadcasts, it is somehow broadcasting six additional open WiFi networks - perhaps three 2.4 and three 5GHz networks.  Although I do utilize an Orbi WiFi6 network, and have security cameras and other gadgets, we have done extensive troubleshooting and have found that these networks remain visible until the router is powered off.  All of these networks appear in our WiFi list as "BROADCOM_GUEST_0_3" (different numbers at the end).  I have located an online manual from Tecnhicolor, which actually shows (Page 64) three 2.4GHz guest networks (and one can presume three 5GHz networks), with a toggle to disable SSID Broadcast.  However, the advice is to possibly access this separate admin portal through, which is useless in this case.  The manual can be viewed here:


I am curious to know if anyone else has come across this, and can offer a solution for disabling these networks?  My support chat was useless.  Thank you very much.
