▶ 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.
