Samsung NP-Q1U/YM/SEG, NP-Q1U/001/SEG manual A5 Check the Network Key Encryption Key settings 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. (E.g., Ch1, Ch5, Ch9, Ch13)

If the SSID option is set to Hide, you will not be able to find the AP on your 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, refer to the owner’s manual supplied with the AP.
