7. Troubleshooting
This chapter describes common problems that may occur with this product and what to do about them.
If any problems occur that are not described here, check to confirm that the re-occur, then contact the
retailer.
When Communication Fails
Check wired LAN communication
Check the wired LAN communication between this product and the connected PC.
-
Check that the LAN cable is connected correctly.
-
Check if the IP addresses and subnet masks of the product and PC are set correctly.
-
The communication with this product is not possible unless the TCP/IP protocol is installed in the
PC.
Check wireless LAN communication
If no problem is detected in the wired LAN communication between the product and PC, check the
wireless LAN communication between the product and access point.
-
The FLEXLAN series is designed to handle a variety of operating formats, and requires software
setting for each type of operation. Check that the settings are appropriate for the type of operation,
and check the format in which communication is being attempted. Also check DIP switch settings.
-
The terminals that cannot communicate with each other may have the same ESSID. Two terminals
with the same ESSID cannot communicate with each other.
-
Check whether the wireless link mode has been set correctly. The wireless link mode of the station
(slave station) must support the wireless link mode set on this product.
-
Check whether communication is restricted by security functions such as the MAC address filtering.
-
Check whether the data encryption setting is the same as that of the recipient.
Communication cannot be performed while data encryption is being switched between ON (enabled)
and OFF (disabled).
Check the peripheral environment and place of installation
-
A nearby source of electromagnetic interference can prevent communication. In general locations
(excluding factories) the following may be sources of electromagnetic emissions.
-
Wireless network not conforming to wireless LAN (IEEE802.11a/b/g/n).
-
When using by 2.4GHz band, electric devices which give off 2.4GHz band electric wave -
microwave oven, security gate (it is an antitheft gate in the shop), copy machine and so on.
Most electromagnetic sources other than wireless networks are local and not continuous, and therefore by
moving the location of the unit and waiting briefly, communication may be possible.
