Troubleshooting
If you are experiencing difficulties with your wireless installation, consult the troubleshooting steps listed
below. For best results, identify the symptoms of the problem you are having and attempt all of the cor-
rective actions listed for the particular symptom.
Symptom
Possible Cause
Corrective Action
Devices will not connect.
Devices have
mismatched net-
work IDs.
• Devices will not connect if they do not have
the same network ID. Verify that both devices
share the same network ID.
Devices are out of
range or there are
obstacles block-
ing the wireless
path.
• Bring devices closer together to see if it alle-
viates the issue. Units will display LINK OK if
they are connected. If devices connect, con-
sider placing closer together permanently, re-
moving any obstacles, or mounting higher.
• Ensure antennas are on parallel plane. De-
vices that are vertically separated will not
have as strong of a connection.
• If communicating over distance of miles, con-
sider installing PDW30-RNA repeaters or a
high gain directional antenna.
Multiple wireless
devices in the
area with the
same ID.
• If there are multiple PDW90 wireless systems
or PDW30 wireless signal bridges, verify that
each system has its own unique network ID.
All units intended to communicate with each
other should share a unique network ID.
Encryption keys
do not match
• If using encryption, ensure that the encryp-
tion keys on both devices match exactly.
Intermittent signal issues.
Signal is too poor. • Check RSSI. If signal is too low, consider
moving devices closer together, clearing ob-
stacles in wireless path, or mounting devices
higher.
• Ensure devices are on parallel plane.
• If communicating over distance of miles, con-
sider installing high gain directional antenna.
Temporary obsta-
cles are blocking
the wireless path.
• Temporary obstacles, such as large trucks or
heavy equipment, can interfere with wireless
path. Consider moving wireless units higher
or to an area with less traffic.
