160Mhz for Mesh?

I get the max speeds can never be attained. When I sit right next to the router on my 2x2 AC iPhone radio with a max linkrate of 866, I get 600. 70-75% of the max link rate is pretty good on average.

I guess my question now is more so around what prospect is there of getting a client WiFi card, adapter, etc. that will have a 2400mbps linkrate that can connect to this AX6000 Orbi.

It seems like since 160mhz is out of the question (because this isn’t permitted on the broadcast / non-backhaul band of the AX6000 from what I’ve read), then that only leaves the option of 4x4 on AX 5ghz 80Mhz if we’re to believe 2400mbps is attainable. I see none of these client facing cards, so maybe 2400mbps on the broadcast band is more advertising mojo than realized speeds (if no devices exist).

Edit: I should clarify that I see wireless AP’s that do 4x4 AX at 80Mhz... I’m referring to a client device. I see some 4x4 AC cards that will do 2100mbps but none that are AX; also don’t see any external USB 3.0 devices with 4x4 at all
