    The RBS750 model is used with the CBK750 and the RBR750 kits. There the same RBS models

      Then why are there THREE 'latest firmware' releases? And which one is really the latest?

       

      My RBS750 satellite has V3.2.16.22 installed and reports this is the latest available.

      The Orbi CBK752 page shows a latest RBS750 (Orbi Satellite) Firmware Version 3.2.16.6 (older than installed?).

      The Security notice says the RBS750 is vulnerable if the RBS750 is running firmware versions prior to 3.2.17.12.

       

      So where do I get V3.2.17.12 ???

       

      And - if I download the version you link for the standalone RBS750, the update fails because the file is for the wrong version of RBS750. I must use the CBK752 download page to get the correct version for my RBS750 from

      https://www.netgear.com/support/product/cbk752.aspx#download

       

      I'm thinking Netgear has no web master to maintain order, and teams change pages willy-nilly... lol.

       

      ps: if I log into the RBS750 via the CBR750 and try using the system firmware updater, it fails: if I direct connect to the RBS750 with a cable, it will accept the 3.2.17.12 version found above. So even their mesh updater is broken.

       

      pps: Now, I wonder when they plan to update the CBR750 to fix the vulnerability. It has the same basics as the RBR750, only with a cable modem stuck on the WAN side of the router.
