●Transmission speed
Set the transmission speed. Automatic setup is possible when the DHCP function (P.3-36) is enabled.
Any of the settings shown in the table below can be selected. Please keep in mind that if you fix at a
higher communication speed, the transmission range will become shorter.

(default)
The transmission speed is automatically varied as ap-
propriate, depending on the distance between the ter-
minal and the access point. The speed is within the
range defined in IEEE802.11b (11, 5.5, 2 or 1 Mbps).

The transmission speed is automatically varied as ap-

minal and the access point. The speed is within the

tween the terminal and the access point.

◎
: Connection is possible. Priority is given to the 11g speed, and high-speed communica-
tions are possible.
○
: Connection is possible. Communications are performed at the 11b speed.
△
: Connection is possible. The throughput will be reduced due to 11b/g negotiation.
×
: Connection is not possible.
●RTS Threshold
This determines whether an RTS packet is transmitted before transmission of a data packet. When the
size of a data packet is larger than the set value, an RTS packet is transmitted, and RTS-CTS control is
performed. When a large number of terminals are connected to the same access point, or terminals
cannot detect each other because they are dispersed remotely even if detection of an access point is
possible, RTS-CTS control becomes effective. Although RTS-CTS control is effective in this case, the
throughput reduces. Usually set it to the default value (2347 bytes).
