When Communication Fails
Check hardware
- If connecting via the wired LAN, check that the LAN cable is connected correctly.
- Check that there are no obstructions in the way of this product.
Check software
- The FLEXLAN-DS540 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 that the AP IP address and subnet settings have been entered.
- Check whether the wireless link mode has been set correctly.
To use the AP in an infrastructure mode, use the user unit in the infrastructure mode as well.
- Check whether communication is restricted by security functions.
- 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).
