► 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.
