[. . . ] EN Dear Customer, Gigaset Communications GmbH is the legal successor to Siemens Home and Office Communication Devices GmbH & Co. KG (SHC), which in turn continued the Gigaset business of Siemens AG. Any statements made by Siemens AG or SHC that are found in the user guides should therefore be understood as statements of Gigaset Communications GmbH. Sehr geehrte Kundin, sehr geehrter Kunde, die Gigaset Communications GmbH ist Rechtsnachfolgerin der Siemens Home and Office Communication Devices GmbH & Co. [. . . ] A much greater range makes it easier to eavesdrop on your wireless data transmission. 96 Configuring the Advanced Settings Super G (108 Mbit/s) With the aid of channel bundling, the Super G transmission mode enables wireless data transfer up to 108 Mbps. The channel for wireless data transfer cannot be changed. You can only use Super G if this function is supported by at least one client in your wireless network. For the best possible data transfer rates, all clients in your LAN should support Super G. Please remember: If you activate Super G as the transmission mode, but it is not supported by all components in your wireless network, then for technical reasons the transfer rate in the network may be significantly lower than the possible maximum of 108 Mbit/s. ì Select the mode for using Super G (108 Mbit/s) for your wireless network to increase the data transmission speed. ­ Static: Wireless transmission is at a rate of just 108 Mbps. Clients that do not support this speed cannot connect to Access Point. ­ Dynamic: If you select this transmission mode, the router accepts subscribers that communicate at different transfer rates and adjusts to the slowest client in the network. menu. ì If you do not wish to use Super G (108 Mbit/s), select Disabled in the selection XR (extended range) Activating XR enables data transfer even in the peripheral areas of your wireless network, albeit at very low data transfer rates. Conversion to XR mode occurs automatically when the signal is weak enough and if the partner station is also XR capable. ì Activate or deactivate XR for your wireless network to increase the range. ì Click on OK to apply the settings. 97 Configuring the Advanced Settings Setting Wireless Security If you are sending data over wireless channels, we recommend that you activate encryption (WEP or WPA) on your wireless network components. We therefore recommend that you choose WPA encryption if it is supported by all components in your wireless network. WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic keys based on TKIP (Temporal Key Integration Protocol) offer increased security. WPA also supports the use of an authentication server. ì In the Wireless Network menu, select Encryption & Authentication. The following security mechanisms are currently available: u WPA2-PSK and WPA2-PSK / WPA-PSK (see page 99) u WAP2 and WPA2 / WPA with authentication server (see page 100) u WEP encryption (Wired Equivalent Privacy) (see page 101) 98 Configuring the Advanced Settings WPA2-PSK and WPA2-PSK / WPA-PSK WPA with Pre-shared Key (WPA-PSK) WPA-PSK is a special WPA mode that provides encryption protection for users at home and in small companies without a company authentication server. Encryption keys are automatically generated with the Pre-shared Key and automatically changed (rekeying) and authenticated between the devices after a certain period of time (Rekey Interval). Which standard of encryption you can choose depends on the components in your wireless network. Every PC (network adapter) that requires access to a wireless network protected by WPA must also support WPA. To find out whether and how you can use WPA on your PC, read your network adapter's operating instructions. If all components support WPA2, select option WPA2-PSK. If you are using network adapters that only support WPA, select the option WPA2-PSK / WPA-PSK. The entries described below are the same for both options. ì Select the required option in the Security field. ì Enter a key in the Pre-shared key field (up to 32 alphanumerical characters) and confirm it by entering it again. ì Apply the settings by clicking OK. 99 Configuring the Advanced Settings WPA and WPA2 with authentication server In large networks (for example in companies), WPA enables the use of an additional authentication service.
