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.
