I have a new Dell 5570 with the AX211 chipset and a Meraki MR57 and I'm running into the same issue. I can only see the 6GHz SSID (and connect to it) If I roll the drivers back to v22.45.1.1.
Windows 11 with AX210/AX211 unable to see 6GHz network using the latest drivers.
I recently bought a new Asus 6E (6GHz) router, and I have four newer laptops with Intel AX210 and AX211 wireless cards installed, all running Windows 11 or Windows 10 Professional. Two of these computers came with Windows 11 Professional and the AX210/AX211 wireless cards new, and the other two were upgraded.
None of my computers can see the 6GHz network. I know the network is broadcasting because my S21 Ultra can see and connect to the 6GHz band. I've tried the latest manufacturer driver 22.130.0.5 and latest Intel driver 22.140.0.3, and neither of them can see the 6GHz network.
In my search for help, I found this previous post Solved: ax210 window 10 21h2 not showing 6GHz networks - Intel Communities and tried the recommended older 22.45.1.1 driver and it worked. However, 22.45.1.1 was only provided by the Microsoft Insider program to enable initially enable Wi-Fi 6E support in Windows 10 and is over fifteen months old.
This doesn't seem like a hardware issue since my phone can connect to the 6GHz network, and my computers can connect to the network using the older driver. I even verified this by purchasing a different Wi-Fi 6E (6GHz) router to confirm it wasn't a router issue. However, I still can't see the 6Ghz network using any other version of the driver.
I have a help ticket open with the computer manufacturer, router manufacturer, and Intel but thought I would ask here as well since it seems like a software issue.
I even made a video showing the issue here.

2022-07-31T22:02:38+00:00 I just installed the 22.45.1.1 driver on my Win 10 system with an AX210 Wi-Fi card and could use the 6 GHz normally.
In another thread, someone was using WPA2-Personal TKIP (I think), but I am using WPA3-Personal with AES.

2022-07-31T03:47:22+00:00 @Ronald S Woan Do you have anything you can show us regarding the 6e Operations. It appears the XB8 has an option for 6e but I cannot find the spec. page for it.
The Razor Blade 15 2022 also seems to indicate a 6e capability. So for me, running an AX210 with an ASUS AXE11000 or AXE16000 with the 6 GHz radio operational and Windows 11, I cannot see a reason why you cannot. Keep in mind, the OP appears to have a non-compatible Wi-Fi 6 router.
Another question, have you previously made any changes to your Registry to try to get the 6 GHz radio operational.

It normally needs WPA3-Personal security. The ASUS AX11000 does not have a 6 GHz radio. You need the AXE11000 or AXE16000 or maybe the AX6000

2022-07-10T09:01:09+00:00 I suppose this may be important, it seems some of the new Dell systems will not do Wi-Fi 6e.
Here is that thread in case it is not you. In that situation it was involving an Intel Killer 1675(AX211) Wi-Fi card.
