I've been battling with the AX210 on my server running Linux and it's peculiar. I run both Linux and W11 on my laptop and the AX210 works great on both OS. However on the server it's being finicky and giving a DL of 6mbps and UL over 1gbps. If I disable the AX it will connect @ 866 UL/DL as if it were on AC. If I play around with other options I can get it to connect at 1200U/D but it's not stable. I've had some other oddities though with that server since switching to Z690/12700K whether it's the board or something else I'm not quite sure and ordered some new M2 cards the other day to internalize the AP function and get a stable client side connection as well. The idea behind the M2's is that they're ~$65 and not $300+ like a 6ghz AP / router.
Anyway... so, I would check the TPL for updated firmware / default it / setup again on the ff chance it shakes something loose in the process that allows the AX210 to connect. Otherwise if you want some other options other than Intel that seem to just work check out

Sometimes it's just easier to buy your way to tranquility. Also, the can't connect to network could be WPA version not setup on the TPL side if the AX is trying WPA3 it should fallback to WPA2 but, Intel sometimes doesn't pick up on the option. Then there's the whole hidden / not hidden issues occasionally. Since it's one device / nic I'm more inclined to swap the M2 and be done with it rather than spend hours on it.
