The Fenvi FV-N450 PCI Express WiFi Adapter supports the 802.11a/b/g/n Wi-Fi standards, providing connectivity for older Wi-Fi networks. While it may not offer the latest Wi-Fi 6 technology, it can still be a useful upgrade for desktop computers looking to connect to legacy networks or for users who do not require the fastest wireless speeds. It's important to note that this adapter's performance and capabilities will be limited to the supported standards, which may not provide the same speed and features as more modern Wi-Fi standards.
