Review on Fenvi AX210 AX210NGW WiFi 6E PCI-E Wifi Card - Ultimate Gaming Adapter with BT5.2, 5400Mbps Speeds, MU-MIMO, and Miracast vPro Support by Joseph Long

Low score because the description was intended to state that Bluetooth requires a USB connection to function. Unfortunately, standard PCIe slots in desktops can only support one peripheral, so you won't find any WiFi/Bluetooth PCIe cards that don't require a USB connection for Bluetooth. Even if you buy a PCIe to M.2 "E" dongle, it has a USB connector. However, a PCIe Mini or PCIe M.2 slot with an "A" or "E" key supports both Wi-Fi and USB, as these interfaces are designed for laptops where it is important to have the to minimize the number of connections. Laptops and some newer motherboards may have an M.2 slot with an "A" or "E" key, and you can purchase the AX210 M.2 version and either your existing M.2 WiFi/Bluetooth module update or connect it. into an empty M.2 slot with the correct key. Please note that M.2 PCIe slots with "A" or "E" buttons do not support SATA storage devices. The "M" key is used for storage devices and does not work with WiFi/Bluetooth cards.
