Orbi firmware update v2.1.4.16 availability

RBK50 Windows 10 PC

I just updated to firmware V2.1.4.16 last night, and it hasn't resolved my problems at all. Both wired, and wireless devices are constantly dropping connection, everything from a roku 4 premiere, to to both my Wife and I's iphone 8 plus, to chromebooks, to ipads. This has been an ongoing issue for several weeks, requiring sometimes HOURLY reboots of my orbi system. In order to reconnect my iphones I constantly have to hit the "renew lease" button in order to be correctly assigned an IP address by the router. None of my other routers by other brands have EVER had this issue, but this one has been happening intermittenly since I purchased the Orbi over a year ago. I know its a firmware issue, and when the orbi works properly, its awesome, but I'm just about done dealing with this, especially because of the extortionate Netgear support policy. 90 days? What kind of BS is that for a modern consumer product. If you have faith in your products, you should be standing behind them for at least a year. And to make it just about impossible to talk to someone beyond that 90 days is also wrong. Oh, and in case anyone is interested, I did contact support within the 90 days, they sent me a new orbi, claiming the hardware was defective (it wasnt) and when the new one had the exact same issue, they did spend time running diagnosics on my network, checking the logs etc, and were eventually able to get it working with a beta firmware patch, but it took 2 weeks to get that far. Now I'm at the mercy of beta firmware being developed for people who hopefully are having the same issues that I'm having. Sorry for ranting, but really tired of dealing with this and listening to my family complain about not having consistent internet access when I spend over $300 on a supposed top of the line mesh system.
