This document is a wireless LAN security configuration guide for NEC NP3250/NP2250/NP1250/NP3250W. It mainly introduces the configuration methods of WPA-PSK, WPA2-PSK, WPA-EAP, and WPA2-EAP.
This guide explains how to configure the enhanced wireless LAN security (WPA/WPA2) on NEC NP3250, NP2250, NP1250 and NP3250W LCD projectors. It provides step‑by‑step instructions for selecting the network type, choosing the security method, and entering the required credentials.
The document also covers setting the projector's date, time, and time‑zone before installing digital certificates, and shows how to verify the authentication status on the information screen. Additional notes include clock behavior when power is removed and password length requirements. This manual is written in Spanish.
| Password length | 8 to 63 characters |
|---|---|
| Built‑in clock runtime without power | Approximately 2 weeks |
Select [CONFIG.] → [INSTALACION] → [CONFIG. DE LA RED], choose the wireless tab, set the network type to [INFRAESTRUCTURA], select WPA‑PSK or WPA2‑PSK, choose TKIP or AES, and enter a key of 8‑63 characters.
An "error de autenticación" message appears because the projector cannot verify the certificate’s expiration date.
The internal clock continues to run for about two weeks without main power.
Open the [INFORMACION] screen from the main menu; the current authentication state is shown in the [AUTENTICACION] field.
