Buying Guide

Interface compatibility

Verify the adapter interface—M.2 CNVio2, half‑mini PCIe, USB, or inline Ethernet—to ensure physical and firmware compatibility with your laptop or dock

Wireless standard and bands

Choose adapters that match your network: Wi‑Fi 6E tri‑band adapters offer 6 GHz support and higher throughput, while older Wireless‑N models are limited to lower speeds

Ethernet features and speed

For wired use, prioritize gigabit (1000 Mbps) support and features like PoE splitting or multiple ethernet ports for Starlink and multi‑device setups

Power and PoE considerations

If you need to power devices over Ethernet, look for passive or active PoE splitters and confirm they do not require external power if you plan to rely solely on PoE

Driver and OS support

Confirm manufacturer driver support for your OS and CPU generation—especially for CNVio2 modules tied to recent Intel platforms—to avoid compatibility issues
