What is the "SYNC_AP" SSID

This has been puzzling me for months.  At first, I thought I was some WIFI IoT device that was in setup mode and I'd just forgotten about it.

 

However, today, I had to move the channel of my main Orbi system a few times because of some outside interference.  Each time, I did, this "SYNC_AP" SSID would move to the same channel.  This leads me to believe that it is related to my Orbi system.  I tried to look up the first 3 digits of the MAC address and it comes up as "no vendor."

 

I used a WIFI analyzer to look closer and found that indeed it uses the same channel as my Orbi system.  But, it shows up using the 802.11n protocol instead of the 802.11ac protocol as my Orbi router and satelites do.

 

Note that I have an RBR40 as my router, two RBS40 and an RBS40V for my satelites.  I've attached a snippet from my WIFI analyzer showing both the weird SSID and one of the SSID entries for my Orbi system.  Note that this only shows up as a 2.4Ghz network and not under 5Ghz.  Also, this doesn't seem to affect the operation of any of my WIFI.

 

Oh, almost forgot, I'm running V2.7.3.22 on my router and RBS40 satellites with V2.6.2.8 on my RBS40V.

 

Anyone have any ideas?

    Mikey94025 , you are spot on.  Yes, I do have a BroadLink Smart Motion Sensor with Hub.  When I unplugged it, the WIFI SSID went away.  When I plugged it in, it came back.

     

    Now, I just have to workout with Broadlink what this is and why its there.

     

    The confusion was that the WIFI channel shifted when I changed my Orbi WIFI channel - thus making me think it was related to my Orbi system.

     

    I had previously tried searching for the term "SYNC_AP" before, but no hits came up - the posting about it on the UAE Amazon web site must have been recent.

     

    Thanks again Mikey94025 !

      Which WiFi Analyzer app is this?

      I have three such apps, but none of them have the same display.  (One can never have too many WiFi apps.)

       

      I suspect something strange.  802.11ac is not a 2.4G capability. (5G only)

        The analyzer I was using was the one located at: https://matthafner.com/wifi-analyzer.

         

        As for the 2.4Ghz and 802.11ac, I was using a 2.4Ghz only WIFI connection at the time I got the snippets.  Of course, the Orbi broadcasts the same SSID on both 5Ghz and 2.4Ghz - perhaps this is the reason for this weird info?

         

        It shows 5Ghz and 802.11ac when I use a 5Ghz WIFI connection as below - but, of course, with a different MAC address:

         

         

        All of the router/satellites show the same thing - an SSID for 2.4Ghz and for 5Ghz with different MAC addresses.

         

        However, I don't think this has anything to do with the "SYNC_AP" SSID.  Note that it only appears once (not multiple times like my main "Orbi06" SSID) and the "SYNC_AP" is only on 2.4Ghz.

    Its got a totally different mac address and wireless N. 

    The Orbi's are wireless AC or AX. 

    I'd be betting on it being an IoT device that you didn't setup or a neighbors device that wasn't setup. 

  • I have an RBR50 or i and have never seen it to my knowledge. Could it be one of the back channels used between the Orbis? I would think it would not broadcast a name but bugs happen.
