TROUBLESHOOTING

This chapter describes common problems which may occur with this product and how

to handle them.

If any problems other than described here occur, check to confirm the re-occurrence.

Then, contact TOSHIBA authorized dealer or service engineer.

•Check if the LAN cables are connected correctly.

•Check if the DIP switch is set correctly.

•Check if the terminals which cannot communicate with each other have the

same ESS ID. Two terminals with different ESS ID cannot communicate with

each other.

•Check if the IP address and subnet settings have been entered.

•Check if the operating mode setting has been correctly entered.

•Check whether or not communication is restricted by security functions.

•Check whether or not the WEP key setting is the same as that of the recipient

device.

If the key placed in the default send key number used for transmission is differ-

ent from that placed in the same location on the recipient device, communica-

tion will not be performed.

•Check if the channel setting has been correctly entered.

•Check if the communication speed setting has been correctly entered.

•A nearby source of electromagnetic interference can prevent communication. In

general locations (excluding factories) the following may be sources of electro-

magnetic emissions.

•2.4GHz band wireless networks not compatible with IEEE 802.11b.

•Microwave ovens

•Security gates

•Elevator motors

•Sometimes communication is hindered by attenuation of electric waves. Attenu-

ation 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 pri-

marily responsible for attenuation are the following.

•Concrete walls

•Metallic surfaces around antennas

•Most electromagnetic sources other than wireless networks are local and not contin-

uous, and therefore by moving the location of the unit and waiting briefly, communi-

cation may be possible.

Also, do not place wireless devices too close together. A distance of at least 1m

should be allowed.

•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 Sta-

tus screen using the utility software.
