Troubleshooting
Blank Pages Appear When Open the Utility Program
It is possibly due to the unavailability of the COM port. Please pay attention to the
Connection and Overall Status field next to the Connect button. Press the
Connect button again to see if the status indicates “Connected.” If not, check to
see if you have another running program that access the same COM port.
No Radio Link
If the Link Quality indicator in the Radio Status panel shows 0%, check the
following for possible causes:
• Make sure that a target radio, an AP or a Station, is turned on and
operating properly by checking LED’s on the radio.
• Make sure that the Signal Strength indicator under Radio Status panel is
not zero. A minimum of 20% is recommended. If the “Signal Strength” is
less than 20%, the distance between the WiSER2400 and the targeted
radio (an AP or another Station) may be too far. Decrease the distance
between the radio pair to see if the radio link can be established.
• If two WiSER2400 radios are meant to operate as a dedicated point-to-
point link, make sure that one radio in the pair has the role of AP and the
other has the role of Station. No link can be established if both radios are
set up as the same role.
• Make sure that the encryption keys are entered correctly if WEP
encryption is enabled.
• Make sure that there is no RF interference present in the radio network.
No Data Transfer While the Radio Link is Good
If the Link Quality indicator shows good link quality, but the host
computer/equipment cannot properly exchange data:
• Make sure the RS232 cables are properly connected to the radios and
computer/equipment.
• Make sure that the RS232 cables in use are not defective.

• Make sure that the COM port on the computer/equipment is available, not
used by another active program/process.
