3. Choose Ad Hoc or Infrastructure Mode depending on your network type A brief explanation of each mode follows Ad Hoc This mode is used for a simple peer to peer network This type of network allows the sharing of local resources only between wireless clients without a wireless Access Point AP 31 Infrastructure This mode allows a wireless LAN to be integrated into an existing wired network through an AP Infrastructure type networks also permit roaming between Access Points while maintaining connection to all network resources Infrastructure mode provides additional features such as WEP security power saving and extended range SSID An acronym for Service Set Identifier SSID is the unique name shared among all clients and Access Points in a wireless network The SSID must be identical for all clients or Access Points participating in the same network The SSID is case sensitive and must not exceed 30 characters Ethernet Conversion The RFC1042 mode is the 802 11 standard conversion method and is selected by default If compatibility with older wireless LAN systems is necessary select another conversion implementation from the Ethernet Conversion drop down list Tx Rate The transmit rate or Tx Rate selects the allowable transfer rates of the wireless client To optimize performance and range the Tx Rate should be set to Fully Automatic which will automatically adjust the transfer speed for best performance and longest range
4. Note The Tx rate setting must be supported by the AP Ifthe AP does not support the Tx rate undesired results may occur WEP An acronym for Wired Equivalent Privacy WEP Is an encryption scheme used to protect your wireless data communications WEP uses a combination of 40 bit keys to provide access control to your network and encryption security for every data transmission To decode a data transmission each wireless client on the network must use an identical 40 bit key NOTE This feature is only available in Infrastructure Mode and must also be enabled on the Access Point Select the WEP tab to enable or disable this feature PS Mode Power Saving Mode enables or disables the power saving features of your wireless adapter When enabled on a laptop the power saving mode can reduce power consumption by the wireless card and extend the battery life of your laptop This setting is only implemented in a network operating in Infrastructure mode Changing the PS mode The PS Mode on your adapter is set to Disabled by default To change the setting select Enabled from the drop down list click OK and wait a few seconds The screen will then is updated and show the current Connection Status Link Quality and Signal Strength Channel This setting specifies the default 802 11 channel used by the Wireless LAN communication In an Infrastructure type network without an Access Point active on the default channel clients will scan
