7 Info(Information) The setup home page will display the information about the current settings of this access point.
8 Assoc(Associations)—Only for Access Point mode This page shows the MAC addresses of devices connected to this Wireless 802.11g Access Point.
9 Wireless (Wireless Configuration) Here you can set/change wireless configuration including visibility status, PHY profiles, SSID, channel, transmission rate … etc. See the description that comes after each function. When you are done with the change, remember to restart this access point to let the new settings take effect. Visibility Status If you select invisible, this AP can not be detected by wireless sniffers; which means all the wireless clients can not associated to this AP unless they know/use the SSID.
10 PHY Profiles You can select different wireless networking hardware (PHY) to meet your wireless environment or for optimal performance. You can thus choose from the list. Wireless Network Name (SSID) The SSID is the unique name shared among all points in your wireless network. The name must be identical for all devices and points attempting to connect to the same network. Channel Shows the selected channel that is currently in use. (There are 14 channels available, depending on the country.) Transmission rate (Mbps) Shows the current transfer rate There are Best (Automatic), Fixed 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54Mbps. )
11 Access (Access Control)-Only for Access Point mode This AP provides MAC Address filtering, which prevents the unauthorized MAC Addresses from accessing your Wireless LAN. Once you check to enable access control, only MAC addresses entered in following fields are allowed to associate to this AP. Note: 1. You can enter 16 MAC Addresses to associate to this AP. 2. You can copy the MAC addresses shown on the Station List and past them to the MAC address table to save the effort of typing and avoid typo as well. Figure: Access Control
12 Advanced (Advanced Wireless) Maximum associated stations 200 Fragmentation threshold To fragment MSDU or MMPDU into small sizes of frames for increasing the reliability of frame (The maximum value of 2346 means no fragmentation is needed) transmission. The performance will be decreased as well, thus a noisy environment is recommended. RTS Threshold RTS (Request To Send) is a control frame sent from the transmitting station to the
13 receiving station requesting permission to transmit. This value is recommended to remain at its default setting of 2432. Should you encounter inconsistent data flow, only minor modifications of this value are recommended. Beacon period This is also called Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the AP to synchronize the wireless network. The default value is 100. DTIM interval DTIM stands for Delivery Traffic Indication Message. A DTIM is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the access point has buffered broadcast or multicast message for associated clients, it sends the next DTIM with a DTIM Interval value. Access Point clients hear and awaken to receive the broadcast and multicast messages.
14 Maximum burst time The amount of time the radio will be reserved to send data without requiring an ACK. Adding a burst time should help throughput for 802.11g clients when AP is running in mixed mode. This number is in units of microseconds. A typical value would be 1000 microseconds. When this number is zero, bursting is disabled. Enable PSM buffer PSM stands for Power Save Mechanisms. Turn this on to enable support for stations in power save mode.
15 Security Here you can enable the WEP and set the WEP key, if you enable the WEP, the client PC also need to set the WEP key. Enable WEP WEP (Wired Equivalent Privacy) encryption can be used to ensure the security of your wireless network. The window allows you to set to 64bit or 128bit Encryption (WEP) by using either Passphrase or Manual Entry methods. Note: To allow Decryption and communication, all wireless devices must share the identical encryption key on the same network. WEP key lengths Select between 64-bit and 128-bit. WEP key You can enter WEP key here or use the default settings shown in the next field. Default WEP key to use Select one of the four keys to encrypt your data. Only
16 the key you select it in the “Default WEP key to use” will take effect. Deny unencrypted data To access this wireless network clients are required to use encryption. This should be checked together with the item “Enable WEP”. Authentication The authentication mode defines configuration options for the sharing of wireless networks to verify identity and access privileges of roaming wireless network cards. You may choose between Open, Shared Authentication, and Both. If the Access Point is using "Open Authentication”, then the wireless adapter will need to be set to the same authentication mode. Shared Authentication is when both the sender and the recipient share a secret key. Select Both for the network adapter to select the Authentication mode automatically depending on the Access Point Authentication mode.
17 IP Addr (IP Address Settings) -Only for Access Point mode Set the management IP for the Wireless 802.11g Access Point, the default IP address is 192.168.1.240. IP Address Mode If you select DHCP, DHCP server will automatically assign IP addresses to this device. And the fields that follow will be grayed out and need no settings. If, otherwise you select Static, you will have to manually set the device IP address.
18 Access point name You can name this Access Point for identification. You can leave it blank without entering anything. However, the name for the access point will be useful for identification especially when there are more than on Access Points in your wireless network.
