Buying Guide

Match form factor to your laptop

Choose M.2 CNVi, half-mini, USB, or inline adapters that physically fit your laptop and available expansion slots

Prioritize protocol and band support

Select adapters with the Wi‑Fi standard and frequency bands (e.g., Wi‑Fi 6E tri‑band) your router and environment use for best throughput

Consider wired connectivity needs

For stable low‑latency use, pick gigabit Ethernet solutions or multiport Starlink/Ethernet adapters when multiple wired devices are needed

Check power and PoE requirements

If deploying PoE accessories, use passive/active PoE splitters or powered adapters that match your PoE injector/switch specifications

Verify chipset and OS compatibility

Confirm the adapter's chipset is supported by your OS and, for CNVio/M.2 modules, that your laptop's CPU generation is compatible
