WPA3 improves authentication where supported, while some older smart-home devices need WPA2-AES. The right choice depends on the client fleet.
Before you change anything
This is a diagnostic entry point. The source supports the general check, not a confirmed root cause for your device.
What to check first
Does another compatible client see or join the same SSID and band?
Record the exact model, hardware revision, firmware and recent change before adjusting settings. If you cannot answer the question, keep the cause open.
Narrow the likely path
| Observation | Next check |
|---|---|
| SSID is missing | Check radio, band, client support and whether the network is hidden. |
| Password is accepted then rejected | Compare WPA mode, saved profile and client capabilities. |
| Internet works but local device fails | Inspect guest isolation and whether both devices share the same LAN. |
Decision after the first test
Check each device's security support and use a separate network for legacy gear if available; avoid WEP or an open main network.
Use a documented next step
Verify before escalating
After each change, repeat the exact failed task. If the result is unchanged, restore the previous setting and use the official support link for your exact hardware revision. Don’t assume a menu or capability from a related model.
