Review on AX210 WiFi 6E Module with Tri-Band BT 5.2 and Windows 10 64-bit Support for Enhanced Laptop and Desktop Wi-Fi by Eric Surabhi

This listing indicates that the card works with Linux but does not say that you need to download and install kernel version 5.10 or higher. The problem is that this is NOT A STABLE CORE. The latest stable Linux kernel is v5.08. IF you decide to install version 5.10 or higher, be prepared to spend the next weekend fixing as many things as possible, as this will break many existing and required features. it will still be a long time before this card is truly Linux compatible. It is a pity that the seller does not want to be honest in this part. My guess is that a sale is a sale no matter how much the seller has to lie to you to make that sale.
