▶ Check the AP settings.
A1 Check if the surroundings are appropriate for a
wireless LAN. A wireless LAN connection may be
limited by the surrounding environment and distance.
Obstacles such as walls and door mats affect the
quality of the wireless LAN signal. You have to install
an AP in a high, open position far away from any
other radio signal sources. If the AP is excessively
far away, or is installed at the end of a building and
you are attempting to use the wireless LAN from the
other end, you may not be able to use the wireless
communication normally because the signal is
blocked by obstacles between you and the AP (such
as a wall).
A2 Check if the AP operates properly. If the AP is not
operating properly, turn it off and on again and try
again.
A3 Check if the AP firmware is the latest version. (For
more information on the AP firmware, ask the AP
manufacturer or your product provider.)
A4 Check if the AP is properly connected to the network.
Connect the LAN cable from the AP to a computer
and check if the network is connected properly.
A5 Check the Network Key (Encryption Key) settings
again. If the automatic password converting function
(passphrase function) is enabled and the wireless
connection is normal but you cannot send data
over the connection, please enter the Network Key
(Encryption Key) manually.
A6 Check the AP settings as follows.
If there are multiple APs running at the same time,
check the channel setting of each AP. If the interval
between the channels of the APs is narrow, you may
experience electromagnetic interference. Set the
channel numbers of the APs so that the internals
between the channels are maximized. (for example,
Ch1, Ch5, Ch9, Ch13) computer.
It is recommended unselecting the Hide option of
the AP. SSID (Service Set ID) is a name used to
distinguish a wireless LAN from other wireless LANs.
It is recommended using Long Preamble. Preamble
is a signal for data transmission synchronization.
Although some APs support Short Preamble, there
might be a compatibility problem.
Because "Fixed" channel selection is more stable
then 'Auto' channel selection, "Fixed" channel
selection is recommended. It is recommended
not using the "Block Any" and "Any Connection
Block" functions. Although these functions block
connections at the client side when the network
name is Any or Blank, it may cause a compatibility
problem.
For more information on the AP settings, see the
owner's manual supplied with the AP.
