Orbi firmware v2.1.1.16 discussion

With the knowledge that Orbi recently supported wired backhaul, I was in Costco about a week ago and saw the RBK53 system on sale for $70 off and impulsively decided to splurge on it.

I haven't had time to install it yet, but have already downloaded 2.1.1.12 and 2.1.1.16 for a manual upgrade when I do get around to cracking open the box.

However, reading the posts here, I find myself wondering if Orbi is worth the effort, but then I also realize that only the posters with problems tend to create posts. But man, the Orbi system certainly sounds like a problematic system with as many posting issues as there are.

Regardless, I intend to give it a try and plan to replace my existing RT-AC56U router and RT-N66U configured as an AP. I have ethernet run from my office to the den and living room where I plan to place the router and satellites and know to update the satellites before the router.

Other than that, is there anything special I should do to prep the Orbi system for installation? Are you guys separating the 2.4 and 5 GHz bands using separate SSIDs? It's been my experience with iPads, iPhones, Android phones, etc. that they tend to grab the first signal they get (typically the 2.4 band) and hang onto it for dear life. 

I presently have separate SSIDs for the 2.4 GHz and 5 GHz bands so the 5 GHz devices can roam and stay with 5 GHz leaving the 2.4 GHz devices to do their own thing on the 2.4 GHz bands.

I have a couple of 8 port Gb switches, but am considering using my old primary router (RT-AC56U as a switch in the office (configured with wifi and DHCP disabled):

Internet/modem->RBR50 WAN port->RT-AC56U (now a switch)

AC56U->RBS50->4k TV

AC56U->printer

AC56U->PC

AC56U->8 port Gb switch on the other side of the house->RBS50, PS3, PS4, Fire TV, TV, etc.

I don't see a need right now for that 2nd 8 port Gb switch.

Once I have the new firmware upgraded, I should have wired backhaul and I expect the upstairs to get excellent wifi coverage with the 3 units positioned pretty much at either end of the house and a satellite near the center.

Any comments/suggestions?
