`ping`, `nslookup`, and `traceroute` are root aliases. The four station-profile slots use lower priority values first. Edits to a disabled profile's SSID, priority, security mode, or secret are staged in RAM and do not interrupt the current Wi-Fi connection. Enabling or disabling a profile, changing an enabled profile, or changing AP policy/configuration applies the new radio policy and may reconnect Wi-Fi. Use `wifi save` to persist working changes. Passwords are not displayed by ordinary status output.
## mDNS
| Command | Description |
|---|---|
| `mdns status` | Show the configured `sak-<suffix>.local` hostname and announcement state. |
| `mdns suffix <value>` | Set a 1–55-character lowercase hostname suffix in RAM. |
| `mdns save` / `mdns load` | Save the working suffix to its independent NVS record or load it. |
| `mdns defaults` / `mdns reset` | Restore the MAC-derived suffix in RAM, or restore and persist it. |
When the Wi-Fi station receives an IPv4 address, the Wi-Fi manager announces `sak-<suffix>.local`. The default suffix is the lower-case hexadecimal STA MAC address. Suffixes may contain lowercase ASCII letters, digits, and internal hyphens only. Changing a suffix while online causes a best-effort reannouncement; mDNS failures do not stop Wi-Fi, UART0, UART1, or native USB access.
