Problem and Indication Possible Cause Corrective Action
No network detected at
Station Adapter (SA-10, SA-
40) workstation.
1. Workstation networking
is improperly configured.
2. UTP cable connection is
faulty.
3. Failure to pass Ethernet
packets.
1. Reset both Access Point and Station
Adapter.
• Re-establish network connection.
• Verify proper workstation network
configuration.
2. Try to ping the remote network. Failure
to detect the network may indicate a
failure to pass Ethernet packets.
3. Verify UTP cable connection. Solid
LINK LED in workstation NIC indicates
proper Ethernet connection.
4. Check monitor messages for errors or
other indications of problems.
5. Check station counters to verify
increase in Ethernet counters which
indicates Ethernet activity (see Section
3.6.1).
High quality signal but
throughput is poor.
1. Too much interference
or multipath propagation.
2. Ethernet port of the unit
may be faulty.
1. Move the unit or the antennas out of
the range of interference.
• Check counters to see if more than
10% of total transmitted frames are
retransmitted fragments (see Section
3.6.1).
• Check if more than 10% of total
received data frames are bad
fragments.
2. Verify Ethernet port activity by checking
Ethernet counters (see Section 3.6.1).
Link signal quality low or not
as good as expected (indoor
installation).
1. Possible multipath or
structural interference.
Reposition the unit outside range of
possible interference.
• Check for heavy metal structures (e.g.
elevators, racks, file cabinets) near
unit.
• Check counters for excessive
retransmissions or received bad
fragments.
• Site may require higher gain
antennas.
• site may require a multicell structure
(multiple AP units) due to
multipath/structural interference.
