Troubleshooting

Check the peripheral environment and place of installation
･ A nearby source of electromagnetic interference can prevent
communication. In general locations (excluding factories) the
following may be sources of electromagnetic emissions.
･ 2.4GHz band wireless networks not compatible with IEEE
802.11b.
･ Microwave ovens
･ Security gates
･ Copiers
･ Elevator motors
Most electromagnetic sources other than wireless networks are
local and not continuous, and therefore by moving the location of
the unit and waiting briefly, communication may be possible.
Also, do not place wireless devices too close together. A distance
of at least 1m should be allowed.
･ Sometimes communication is hindered by attenuation of electric
waves. Attenuation occurs naturally as distance from the source
of transmission increases, but may also be caused by objects in
the path of the transmission. The objects primarily responsible
for attenuation are the following.
･ Concrete walls
･ Metallic surfaces around antennas
Stable transmission at 11Mbps requires an RSSI value of at least 80.
The RSSI value can be verified on the Wireless Device Information
tab on the Status screen using the utility software.
When SNMP Connections Fail
･ It is possible that the device cannot locate a control parameter, or
that a private MIB has not been compiled. See Chapter 6.
･ If MIB settings have not been made, the correct community name
may not have been entered. Be sure the community name
setting agrees with the network manager's setting.
･ Check the SNMP settings that are being used.
