Let me explain. I have had my Netgear A6210 for several years now and it has worked flawlessly all that time. I can connect to the 2.4GHZ WIFI and the 5GHZ Wifi bands at will. The problem started when I changed my internet provider from Cox Cable to Verizon 5G Home internet service.
The equipment Verizon provided me is the ARC-XCI55AX. This device provides both 2.4 and 5GHZ bands on the same SSID, and it decides which band is assigned to any device connected to it.
With the ARC, the Netgear A6210 will only connect the 2.4GHZ band. If I go into the Netgear and force it to only connect to 5GHZ, it can not see the signal of the Verizon device. Not even the 2.4GHZ side of it.
It I leave the Netgear hardware setting to connect to "2.4 and 5.0" bands, it will only connect to 2.4 GHZ

OK. The wifi comes from the ARC-XCI55AX, a modem/gateway router.
I doubt if the router sets the bands. That is usually a client side thing. Have you looked there to see what it is doing? If it really does decide, then the adapter can't do much about it.
Hard to know which causes the blockage, the ARC-XCI55AX or the A6210. Maybe even the host that manages the A6210. probably a Windows PC.
What have you done that tells you that the USB adapter is the issue?
Have you tried running the Windows Network Troubleshooter?
Have you told the A6210 to forget past connections to the SSID involved?
As you can see, lots of places where things can go wrong. You need to investigate them all. Don't jump to the conclusion that the A6210 causes you this grief.

I've logged into the ARC as Admin, to see what it's doing internally. No luck there. But I'm still digging into this. The way the ARC works is that it broadcasts only one SSID on the primary network. This SSID contains both 2.4 and 5 GHZ bands. When I connect a device to the WIFI, I can not assign which band the device will be using. It does not give me that option. So the ARC does it on it's own.

I have 53 devices connected to the WIFI router. The smart devices are on 2.4GHZ, by design. There are roughly 13 devices that are connected which connects to both bands easily. these are cell phones, laptops, TV's, google home speakers, fire tablets. These devices see and connect to the 5GHZ band with no problem. The Netgear A6210 is the only device that has this problem of not seeing 5GHZ. If I force it to use 5GHZ only, it can not see the router WIFI signal.
Have you tried running the Windows Network Troubleshooter?
Yes. No problem found.
Have you told the A6210 to forget past connections to the SSID involved?
Yes. Also uninstalled and reinstalled the latest driver
