Unable to connect to the AP.
(The connection is dropped frequently.)
[Close to the device using the same frequency, OK]
A1 and other wireless LAN devices, wireless video transceivers, microwave, plasma,
such as light bulbs, etc. If you have products that use the frequency channel
interference may occur. Other product and channel interference occurs, AP change to
a different channel is recommended.
A2 IEEE802.11g mode operation, if the environment around the IEEE802.11b devices
operate in mixed mode operation, so that rates can cause a decrease in severe cases
can be disconnected.
[Authentication check]
A IEEE 802.1x authentication in an environment that does not use IEEE 802.1x
network authentication option is selected, if time allows and then disconnects.
Wireless Network Properties, view the properties of the AP. Authentication using IEEE
802.1x authentication on the network tab, uncheck the window. For more information
about authentication servers, contact your network administrator.
[AP Settings section of the check]
A1 is suitable for use in the wireless LAN environment check. The surrounding

Obstacles such as walls and doors affect the wireless access. AP to the high places,
around the teuin place, and the effects of propagation away from the other install. AP
has so far been installed, or installed in the building at one end to the other end, if you

If more than one AP, each AP to exist at the same time set the number of channels to
check. If the narrow channel between the AP interval can cause interference. Each AP
is set to be away from the left channel number. (Example: Ch1, Ch5, Ch9, Ch13)
AP's SSID is set to hidden options, the computer can not detect the AP. AP to set the
hidden option is recommended termination. SSID (Service Set ID) that differentiates
one wireless LAN to give other wireless raeneurobuteo name.
It is recommended that you use Long Preamble. Preamble for synchronizing data
transmission signal to Iran, AP, depending on the type of equipment to support the
Short Preamble, but may be compatible on the issues.
Automatic channel setting a fixed channel settings (Auto channel selection), so the
more stable it is recommended to set a fixed channel. Block Any, Any Connection
Block and is recommended not to use them. This network name in the Client Any one
or Blank ability to disallow the connection, but there may be compatibility issues.
