Alvarion
Problem and
Indication
Possible Cause Corrective Action
Wireless link
established, but
there is no Ethernet
activity (BU-
DS.5800 and RB-
DS.5800 units).
1. Ethernet hub port or
UTP cable is faulty.
2. Ethernet port in unit
is faulty.
3. The RB-DS.5800 is
associated to a
BU-DS.5800 unit that is
not connected correctly
to the LAN.
1. Check that the LINK LED is lighted
Green. If this is not the case, the port is
inactive. Try another port on the hub or
another UTP cable.
2. Verify that Ethernet port in unit is
working. Ping unit to verify Ethernet
connection.
3. Verify that you are using a cross-over
UTP cable (pins 1 & 3, 2 & 6) if
connected directly to a workstation, or a
straight-through cable if connected to a
hub.
4. Check the unit’s LINK LED indicator
and check the Ethernet counters in the
monitor to verify Ethernet activity.
5. Check that the BU-DS.5800 is
correctly connected to the LAN.
Wireless link
established, but
poor or erratic
performance.
1. Antennas not aligned.
2. The link is too long.
3. Link path not clear.
1. Realign antennas.
2. Verify optimal link distence for the
antennas you are using.
3. Relocate the link to a clear path or
raise the antennas above any objects.
4. Relocate the antennas away from
interference.
5. Change channels or add a filter.
6. See FAQ question “Can a 2.4 GHz
network operate in the same area as a
BreezeNET DS.5800”.
