In this chapter, the advanced settings which include the settings of wireless, firewall, port forwarding, routing and
network will be introduced.
Wireless Settings
Click “Wireless” in the operation navigation to list the submenu of wireless settings.
Basic Settings
z “Wireless interface”: It specifies the wireless interface. “802.11b/g Compatible” means that you can use both
the 802.11b device and the 802.11g device to connect to 3G ROUTER via WLAN; “802.11g Only” means
that only the 802.11g device can be used to connect to 3G ROUTER via WLAN; “Disable” means that you
can’t use the wireless device to connect to 3G ROUTER via WLAN.
z “SSID”: SSID(the service set identifier) is used to identify a WLAN. A wireless device and a wireless router
can perform normal data communication only when they have the same SSIDs. To ensure the WLAN security,
do not use the default SSID. You can enter any character string as the SSID.
z “Channel”: IEEE 802.11b/g divides ISM band into multiple channels, and the number of channels varies with
different countries. You should set the same numbers for the channel.
z “SSID broadcast”: If the SSID broadcast is disabled, 3G ROUTER does not broadcast the SSID of WLAN.
Before accessing the WLAN, the device must obtain the SSID of the WLAN. Thus, the security of WLAN is
improved.
Wireless Advanced Settings
z “Beacon period”: The beacon period value indicates the frequency interval of the beacon. A beacon is a
packet broadcast by the router to synchronize the wireless network.
z “RTS threshold control”: If a network packet is smaller than the preset RTS threshold size, the RTS
mechanism will not be enabled. The router sends Request to Send(RTS) frames to a particular receiving
station and negotiates the sending of a data frame.
z “Fragmentation control”: This value specifies the maximum size for a packet before data is fragmented into
