Orbi firmware update v2.1.4.16 availability

I just registered for the first and last time to post  my experience with the Orbi RBK50 kit and RBW30. I purchased the RBK50 back in 2017 and later needed to add RBW30 in early 2018.  The nuances with WIFI disconnections the other Netgear forums posts had reported  in the past about the Orbi system I've also experienced, but was infrequent for the first few months and thought future firmware fixes will address these issues eventually.   Up until this Orbi Mesh System, I've had a pretty good no issues experience with several Netgear WNDR routers in the past and recommeded family and friends to Netgear up until this Orbi line of product. I understand there is no one perfect brand  and each have their own issues of some kind. I'm not a novice when it comes to troubleshooting network devices, but I do know when you purchase a "working" product it should work right out of the box to some degree, with some issues ironed out in the beginnning with firmware updates is understandable but that's not the case with the Orbi RBK50 kit.  I've been keeping up with the issues since around Sept. 2017, workarounds, and firmware updates to date from these Netgear forums. Sure it's got better, but still unreliable. I'm not here for troubleshooting advice, but this firmware update v2.1.4.16 was the last chance I gave Netgear to  fix all WIFI disconnection issues I've experienced with Orbi .  I've performed the firmware update to all of my Orbi devices to v.2.1.4.16 and performed factory reset to all my Orbi devices. Worked for about a day before disconnection issues came back. I really didn't want to spend more money for an alternate Mesh system out there if I didn't have to, but this whole Orbi system has wasted too much of my time and over the course of  almost a  year waiting for a stable firmware fix. I've come to a conclusion myself that this Orbi product line is simply unreliable and add my recommendation to others to stay away from Netgear's Orbi products.
