Yes, great hyperbole from the above posts.
We'll see where WiFi 7 is at in a few short months.
When I finally upgraded to an RT-AC68U from an RT-N66U, I knew I had waited too long (it was years). Same thing when I upgraded from that RT-AC68U to an RT-AC3100 and then to the RT-AC86U. When I bought an RT-AX88U (which was quickly sold) the promise of AX was more than just a glimmer or marketing hype, and I bought the pair of RT-AX86Us very quickly (~6 months after they were available and 'proven'). Same for the GT-AX6000.
With the second set of AX class routers (and the 2.5GbE backhaul they used), my network speeds more than doubled and the latency decreased noticeably too. Impressively, this was with the same 1Gbps symmetrical Fibre connection and the same mix of client devices too.
The upgrades to my network were real. Particularly to my 2.5GbE NAS usage (with two additional 2.5GbE QNAP switches at each router to share that 2.5GbE goodness with). But also noticeable on WiFi too (I could feel the ISP connection was limited by the previous RT-AX88U router and its lower-performing hardware/SDKs).
When the time is right, I will test WiFi 7 routers in my own network and make a decision then (I'm sure you'll read a few posts from me on that, right here, of course).
If WiFi 7 gives even the same boost (~20% greater throughput at the same distance, which equates to a 20% decrease in latency too) as the GT-AX6000 has, depending on my budget at that time (and the prices I can sell the current gear at), it may be worth switching/upgrading once again.
But what I do know is that I won't be making that decision based merely on specs or other abstract mind games. The gains I like to see must be real, not imaginary. And the cons described above show little understanding of all the points I'm making (or even how WiFi/RF works when the spectrum is expanded so slightly).
One thing I know for sure: manufacturers don't (intentionally) release new products to be equal to their previous offerings (they're not just trying to outdo their previous products, but also their competitors too). Anyone who operates on that belief is only fooling themselves and/or doesn't know how to buy the right products for their use cases.
Yes, there are only a few worthwhile models each year worth recommending, with a lot of duds mixed in. But that is what return policies are for. If the new doesn't surpass the old, don't keep it. Return and try again in a few weeks/months with something else.
