EZ C ONNECT ™ 802.11 A W IR ELESS A CCESS P OINT 16 Note: The “Advanced Setup” screen allows you to v iew and change the current configurations of the Access Point. Aft er modifying the configuration parameters, you must click on the “Apply” button to save the changes.
S YSTEM C ONFIGURATION 17 Channel Radio Channel : The radio channel through which the Ac cess Point communicates to PCs in its BSS. (Default: “52” for U S and “38” for Japan) Note that the DC channel for wireless clients is automatically set to the same as that used by the Access Point to which it is linked.
EZ C ONNECT ™ 802.11 A W IR ELESS A CCESS P OINT 18 Note: During “N ormal Mode,” the ch annel bandwidth i s 20MHz. During “Turbo Mode,” the channel bandwidth is increased to 40MHz. However, there will only be three chan nels available when the “Tu rbo Mode” is enabled (Onl y 1 channel in Japan).
S YSTEM C ONFIGURATION 19 Synchronization In order to obtain transmission, the Access Point and connected clients need to be synchronized. Beacon Interval (20-1000) : Set the interval value of beacon between synchronized frames. These synch ronous frames also contain indication of frames that nee d to transmit to the power-saved stations.
EZ C ONNECT ™ 802.11 A W IR ELESS A CCESS P OINT 20 The DTIM is the interval between two syn chronous frames with broadcast infor mation. If you set the v alue to 2, th e access point will save all multicast frames for the BSS and forward them after every second beacon.
S YSTEM C ONFIGURATION 21 RTS Len gth (256-2346) : Set the R TS (Request to Send) frame length. Y ou may configure the access point to initiate an RTS frame sequence always, never , or only on frames longer than a specified length.
22 by the network DHCP server . (Default: Disable) Note: If there is no DHCP server o n your network, then the access point will auto matically start up with its default IP address, 192.
S YSTEM C ONFIGURATION 23 Encryption Wired Eq uivalent Priv acy (WEP) is implement ed in this device t o prevent unautho rized access to your wi reless network. The W EP setting must be the same on each client in your wireless network. For more secure data transmission, you may set the WEP to prevent unautho rized access to your wirele ss network.
EZ C ONNECT ™ 802.11 A W IR ELESS A CCESS P OINT 24 If Shared Key is enabled, the WEP should be en abled and at least one shared key should be defined.
S YSTEM C ONFIGURATION 25 Using MAC Filter Set the MAC filter to filter out specified MAC addresses. The Access Control List (ACL) provides a mechanism to take certain actions based on the stations MAC addr ess. Any frames with a source or destination MAC address entered in this table will be filtered from the Access Point.
