How to connect to the Internet/Intranet by NAPS-02
with LAN card

When the DHCP server is prepared in customer's LAN environment, wireless LAN service can be provided only by inserting LAN card in NAPS-02. (If there is no DHCP server in customer's network, to set network information (Refer to the router set chapter of the manual) so that the wireless LAN service can be provided.)

[Relation between IP address system on customer side LAN and IP address on wireless LAN side]

Customer side LAN is 192.168.xxx.yyy ---> wireless LAN side is set to
Customer sides LAN is other addressing ---> wireless LAN side is set to



Put the NAPS-02 on the safe place and insert LAN card into PCMCIA slot of NAPS-02.

(Please do not turn on the power supply until the card is put. )


Connect LAN card to the hub/switch in the customers LAN.

(Use straight cable to connect hub/switch. Cross-over cable to connect directly the router or the computer.)


Turn on the power supply to start NAPS-02.

If the card inserted this time is different from the card last time, NAPS-02 will re-load the card information file from FlashROM then it takes some more time to launch NAPS-02 (around 2-3min).

(Please see the reference in the manual about the behavior of LED under launching. )


NAPS-02 acquires DHCP information from the customer's LAN.

Afterwards, a preparation necessary for wireless LAN service is complete.

  • Confirmation of LAN connection normality
  • Acquisition of IP address of NAPS-02 (outside address)
  • Acquisition of DNS server address
  • Acquisition of NTP time
    (For the account time adjustment and for the self check)

Wireless LAN side for the computers connection starts.

When wireless LAN starts, the computers in wireless LAN area receives the signal of wireless LAN (beacon).

After a while, IP address is distributed from the DHCP server of NAPS-02.

At this time, the IP address in wireless LAN side is different from customer side existing LAN, not to conflict each other..

(The method of connecting the computers to the Internet via NAPS-02 is described in detail to "How to connect to the Internet from the notebook computers" on the post-page. )
