Hi LSY,
Thank you for contacting to Microsoft Community.
As you mentioned, this is normal on Windows since multiple users have reported same observation. Windows 11 doesn’t add a “Wi‑Fi 6/6E/7” badge to the taskbar Wi‑Fi icon the way some Android devices (e.g., Galaxy) do. Instead, Windows shows the connection type in Settings → Network & internet → Wi‑Fi → (your network) → Properties, where you’ll see the Protocol (e.g., “Wi‑Fi 6 (802.11ax)”) and Network band (e.g., “6 GHz”). I suggest you verify via protocol and band fields or cmd, not via a special tray icon.
