Samsung NP35RP05S4/SES, NP35RH033E/SEG manual A6 Check the network key settings encryption key

A5 Verify whether the AP has been properly connected to the network.

Verify whether the network is operating normally by connecting the wired net- work cable, which has been connected to the AP, to your computer.

A6 Check the network key settings (encryption key).

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 envi- ronment.)

When several APs are present simultaneously, check the channel setting for each AP. When different APs are using nearby channels, interference may occur between electronic waves. Set the APs’ 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 canceling the “Hide” option for an AP. The SSID is a name for distinguishing one wireless LAN from another wireless LAN.

It is recommended using Long Preamble. Preamble is a signal for data trans- mission 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 setting a static channel.

Q5 In the Windows XP ‘Available wireless networks’ window, the Wireless Network Connection is displayed as ‘Not Available’.

A1 When there is a Wireless LAN button, ensure that the Wireless LAN button is turned on. (Refer to ”Hot Keys” (P. 1-11))

A2 Check if there is additional program for a wireless LAN connection installed. Windows XP supports wireless LAN connections through the Wireless Zero Configuration (WZC) service. Therefore, an additional program for wireless LAN connection is not required, unless the network requires a specific program. However, installation of some wireless LAN related programs may sometimes dis- able the [View Available Wireless Networks] window supported by WZC service. Exit the wireless LAN related program then check whether the window is enabled.
