Thank you for all your valuable feedback!
So please excuse me, as I don’t understand all the router specs and lettering/numbering (AX AU 802.11x etc.). I’m an old mainframe guy, give me an IBM mainframe, and I’ll make it sing with any OS you want and any device you’d like to attach. Read all those cryptic IBM manuals with ease. But this, please give me more time.
I’d like to replace my RT-N66U with another Asus (I have absolutely no problems with this router), but not a given. I want to be ready for Wi Fi-6 and want something faster. I have as ARRIS SURFboard SB8200 DOCSIS 3.1 Gigabit Cable Modem with a a 1 Gig speed plan with my ISP. I know my router is the weakest link.
What is confusing to me are the specs for my router. It show the 802.11n data rate up to 450 Mbps, while most of the other routers have a maximum of 300-400 Mbps at 2.4 GHz (I think).
I’m running 2 HD TV’s (1-4k, 1-8k and watch only 1 at a time), Home Security, Aquarium Lights, Laptops, iPhones and appliances to name a few. The only issue I have is watching HD TV (very little buffering). Granted, I’m not viewing the full potential of my TV’s. All this contained in a 1400 sq ft. condo with 2 floors and no cement walls/floors.
I’m totally confused, and would appreciate any/all advice. I’ve looked at the RT-AX88U, RT-AX92U, RT-AX3000 and various Netgear Nighthawk models (AX12 etc) and read about the new and upcoming Asus RT-AX86U (even though I don't do gaming). I just can’t decide. I would rather skip the AiMesh models, as my current router works fine in the middle of my condo on the first floor. Price is not an issue.
Thanks again!
