A2
Verify whether the same network key (encryption
key) has been entered for both the AP and the
computer. The network key is an encryption key for
encrypting the data transmitted between the AP and
the computer. It is recommended setting the network
key manually.
► Check the AP Settings
For the AP settings, refer to the User Guide provided
by the AP manufacturer.
A3
Verify whether the environment is suitable for using
a wireless LAN. The use of a wireless LAN may be
restricted according to the environment and distance.
Obstacles such as walls or doors affect the use of
a wireless LAN. Install the AP in a high and open
space, 50cm from the wall and far removed from any
other radio signal sources.
A4
Verify whether the AP is operating properly.
● When the AP is not operating normally, turn off
the AP, wait a short while, and turn it on again.
● Verify whether the AP’s firmware is the most
recent version. (Contact the AP manufacturer or
the place where you purchased the AP for details
of the AP firmware.)
A5
Verify whether the AP has been properly connected
to the network. Verify whether the network is
operating normally by connecting the wired network
cable, which has been connected to the AP, to your
computer.
A6
Check the network key settings (encryption
key) again. When automatic code conversion (a
passphrase function) has been selected and data
communication is not functioning even with a normal
wireless connection, it is recommended entering the
network key (encryption key) manually.
A7
Check the AP settings as follows. (The following is
recommended for a standard environment and thus
may differ according to the specific wireless network
environment.)
● When several APs are present simultaneously,
check the channel settings for each AP. When
different APs are using nearby channels,
interference may occur between the electronic
waves. Set the AP channels further apart from
each other.
(Ex: Ch1, Ch5, Ch9, Ch13)
● When an AP’s SSID (Service Set ID) option is set
to “Hide”, you cannot search for that AP on the
computer. We recommend unselecting the “Hide”
option for the AP. The SSID is a name used for
distinguishing one wireless LAN from another
wireless LAN.
● It is recommended using Long Preamble.
Preamble is a signal for data transmission
synchronization. Short Preamble may be
supported by some types of APs but may cause
compatibility problems.
● It is recommended using a static IP.
● Since static channel selection is more reliable
than auto channel selection, it is recommended
using a static channel.
