why does wifi OFDMA degrade performance so badly?
my concern is with two PCs, filesharing to each other, both on the same wifi channel. I would upload a clear well-composed video illustrating it, but this forum doesn't support it. so I expect n...

either Netgear firmware, its chipset, or the intel AX210.
Inhell AX210, just like AX200, BE200, and BE202 do work brilliant with recent Netgear's SMB APs, as well as most other business AP brands I can get a hands-on. No idea if the the same applies to the consumer models.

and, is there any Netgear product that does a better job.
Sure, certainly all WAX6xx (all Qualcomm based) and WAX220 (MediaTek MK7986AV/MT7978DM based) - all very nice products supporting multi VLAN/multi SSID clients very well. Sorry friends, this is more my competency area - Netgear does think the same, they share many SMB units with me for Beta testing, but NUL NIL ZERO fancy consumer devices. Therefore, I can't talk more about these consumer units.
Some oddities in common to certain Qualcomm (WAX630E) and according to reports also on WAX220 and some other MediaTek based units like the MR60/MS60 troubles with what I would designate as a bug in the VLAN L2 communication between different VLANS, leading to the situation that WiFi clients on one radio (6 GHz vs other on the 630E) and 5 GHz vs. 2.4 GHz on the Nighthawk Mesh MR60/MK60 struggle under some well documented conditions. Some issues ref. WAX630E are confirmed and somewhere in between "we don't fix" (early Netgear response) to "we fix when we figure out" as of today. Let's hope it's work in progress for Q1/2024 8-)
see for yourself. it's not a difficult experiment.
try filesharing between two PCs both on the same wifi channel.
OFDMA=off. then OFDMA=on is hideous.
there's no excuse for it.
seeing is believing.
Retired_Member please allow some curiosity questions:
The RAX70/RAX78 does only have one MultiGig port, the one connected to your cable modem/router MultiGig port of course. All other LAN ports are - despite of the misleading MultiGig marking (for connecting a WAN device supporting a LAG) - just GbE only.
Do you have a LAG configured for the LAN side (LAN port 3+4) to a LAG? Is this LAG properly configured for connecting a multi-gig switch, or for the sake direct on your PC (also for a dynamic LACP LAG).
Badly operating LAGs, incorrectly configured on both sides - for example as static LAGs instead of dynamic LACP LAG - can cause such odd low speed issues.

both PCs are connected to the router via wifi. (same channel)
no traffic passes through the ethernet ports for this.
they could be unplugged altogether.
