Communication (Windows OS type) FAQ

The ping command does not reach the PC from the terminal by wireless communication. How should I isolate the cause?

Generally, isolate the cause by the following procedure:

  1. Check to see if the terminal's antenna icon is displayed.
    x mark displayed .... Error in wireless settings Check SSID, WEP and other settings again.
    Antenna icon displayed ... Wireless settings OK ->Go to (2)
  2. Try entering and issuing the ping command to the access point.
    ping command does not reach access point ... Problem on network between PC and access point
    ping command reaches access point ... A probable cause is that the terminal is connected to the access point of a different segment by the same SSID.
    Check to see if there is an access point with the same SSID nearby.
The ping command does not reach the terminal from the PC by a wireless communication. How should I isolate the cause?

A possible cause is that the wireless connection is not in an open state. Set the wireless connection to a waiting state in the system menu, and check again.
If there is no problem, isolate the cause by the same procedure as in the previous question.

Wireless communication is not possible on only a specific Handy Terminal. What are the possible causes?

A probable cause is that "MAC address filtering" is set to the access point or that unique IP addresses are not set.
Pay particular attention to Handy Terminals that have been newly added on or swapped as a replacement for repair.

Tell me some examples where wireless electromagnetic interference is caused.

Below are some examples of electromagnetic interference:

  1. Near specific machinery -> Noise is generated from machinery
  2. Locations with lots of metal surfaces -> Noise is generated by a multipath delay
  3. Near a cordless phone -> Radio frequency interference

Be sure to conduct a site survey before installing a wireless Handy Terminal.

It is difficult to switch from a far access point to a close one (the handy terminal does not perform roaming). Can you suggest a good method to solve this problem?

You can make the BT switch between access points more quickly by increasing the roaming threshold on the "213. Connection Parameters" screen on the BT system menu. However, frequent switching between access points may make the battery power be consumed more quickly, and communication may be delayed when the BT switches. We ask that you perform sufficient on-site tests where you will use the BT.
