Wireless link
established, but
there is no
Ethernet activity
(BU-DS.11 and
RB-DS.11 units).
Possible Cause
Power cord is not
properly connected.
1. Power supply to units
may be faulty
2. The RB-DS.11 units
may not have the same
ESSID as the BU-
DS.11.
1. Power supply to units
may be faulty.
2. Cables may be
improperly connected
3. There may be some
problem with antenna
installation.
1. Ethernet hub port or
UTP cable is faulty.
2. Ethernet port in unit
is faulty.
3. The RB-DS.11 is
associated to a
BU-DS.11 unit that is
not connected correctly
to the LAN.
Corrective Action
Verify power cord is properly connected to the BreezeNET unit
and to the power outlet.
1. Verify power to units.
2. Verify that all units in the network have the same ESSID
(ESSID must be identical in all units in the WLAN; the ESSID is
case sensitive). Check that the units are on the same channel.
3. Verify wireless link:
Set BU-DS.11 and RB-DS.11 units side by side.
Power on each unit and see if a wireless link is established (even
"D" models without their external antennas should establish a link
if placed side by side).
If the units fail to associate, reset units to factory default values.
The units should now establish a wireless link.
1. Verify power to units.
2. Verify that all cables are connected securely.
3. Refer to previous Section and verify wireless link between the
units.
4. Verify that the antenna(s) are properly installed (see relevant
section in this manual):
Check antenna alignment.
Verify that antenna polarization is the same at both ends.
Verify that the range matches specifications.
Verify line-of-sight/antenna alignment/antenna height.
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 that the BU-DS.11 is correctly connected to the LAN.
