Yeah, I'm definitely not going to pick up a now obsolete second AC66U atp, I came to my senses shortly after writing that, lol. Also pertinent to mention my current lower mid tier ISP plan doesn't capitalize on the full 1.3gps 5ghz link rate anyhow, I was more just (maybe irrationally) bothered...
Something else that occurred to me, you'd think whatever voodoo they sweeten the specs with would have gone back for years, so that the claim over *actual* performance would still be about the same proportionally with the AC66U. Looking just now the 66 claimed up to 1.3gbps 5ghz AC, basically...
Ahh. So getting extra sneaky with specs IG. All I know is the 5ghz connection in the way I outlined above was superior with the several years older At66U, so it's highly weird. So I guess maybe with the implementation of the AX ability in this model came a slight reduction in AC 5ghz...
802.11ac 5Ghz: up to 1.7 Gbps
802.11ax 2.4Ghz: up to 574 Mbps
802.11ax 5Ghz: up to 2.4 Gbps
Though only the first would really apply since my USB adaptor doesn't do AX and I believe only my phone does. Although I should clarify the AX3000 isn't significantly pricer than the ACB66U at all, less...
RT-AX57 = AX3000. Which is several generations newer, pricier, and with better specs across the board than the AC66U B1. So I somehow "got what I paid for" in the sense you imply by purchasing a more expensive and all around superior on paper successor to the AC66U? Fascinating.
So basically ala the title, I just upgraded from an AC66U B1 to an AX57 as main router, to use both in an AImesh framework (AC66U as node) in hopes of achieving better penetration into a far upstairs corner of the house with which the AC66U (situated downstairs somewhat oppositely) previously...
