- On PC or Mac, check Wi-Fi connection properties for protocol and frequency.
- The easiest way: Check the label on your router—it usually lists the model name and supported Wi-Fi standards (e.g., Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E, AX1800).
- Alternatively, search the model number online for full specifications.
- For more technical details, check your device’s Wi-Fi settings for terms like 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6).
