If your machine's M.2 NGFF WIFI wireless network card slot only supports CNVi protocol wireless network cards, you cannot use this product.

This product supports the use of 2230 NVMe protocol M.2 NGFF SSD connected to PCIE protocol M.2 NGFF WiFi network card interface slot. Please note that if your machine's WiFi network card interface only supports CNVi protocol, it cannot be used. It is important to note that this usage method may not support high-power hard drives with a rated current of 2 amps or more, as the M.2 wifi network card interface is designed with a small power capacity (manufacturers cannot design a large capacity power supply for a low-power wireless network card).
