6 Introduction to 802.11b Wireless The IEEE 802.11b standard is the most widely used standard for wireless LANs today. A wireless LAN (WLAN) is a cellular computer network that transmits data using radio signals instead of cables. WLAN technology is commonly used in home, small office and large corporate networks. WLAN devices have a high degree of[...]

7 in its broadcast range. WLAN nodes transmit digital data using FM (frequency modulation) radio signals. WLAN devices generate a carrier wave and modulate this signal using various techniques. In this way, digital data can then be superimposed onto the carrier signal. This radio signal carries data to WLAN devices within range of the transmitting [...]

8 Hardware Installation The DSL-G664T functions on three separate networks: a wired Ethernet LAN, a wireless LAN and a wired ADSL WAN. Placement of the Router must take into account the fact that it is connected to these three networks with three types of media.

22 Wireless Security The DSL-G664T offers three types of network security: WEP , 802.1X , and WPA . WEP WEP (Wireless Encryption Protocol) encryption can be enabled for security and privacy. WEP encrypts the data portion of each frame transmitted from the wireless adapter using one of the predefined keys. The router offers 64-, 128, or 256-bit encr[...]

23 Important Note: If encryption of any kind, at any level is applied to the Router, all devices on the network must comply with all security measures. 802.1X Some network-security experts now recommend that wireless networks use 802.1X security measures to overcome some weaknesses in standard WEP applications. A RADIUS server is used to authentica[...]

24 WPA (Wi-Fi Protected Access) Wi-Fi Protected Access was designed to provide improved data encryption, perceived as weak in WEP, and to provide user authentication, largely nonexistent in WEP. For most small networks, such as in a small business or home-based enterprise, WPA is the easiest way to obtain effective network security. Of the three op[...]

25 Enter the appropriate values, then click Apply . Important Note: If encryption of any kind, at any level is applied to the Router, all devices on the network must comply with all security measures.

IGMP packets are used to control multicasts and discontinue multicasts to individual IP addresses when they are no longer needed. Figure 4-10. Multicast pass-through menu To enabl[...]

53 Static Routing Use Static Routing to specify a route used for data traffic within your Ethernet LAN or to route data on the WAN. This is used to specify that all packets destined for a particular network or subnet use a predetermined gateway. Figure 4-11. Static Routing menu To add a static route, choose a connection from the pull-down menu and [...]

54 Dynamic Routing The Router supports RIP v1 and RIP v2 used to share routing tables with other Layer 3 routing devices. It also supports use of password protection which requires password verification for RIP requests. Use the Dynamic Routing menu to enable RIP and if desired to configure password protection. Figure 4-12. D y namic Routing (RIP) [...]

55 Wireless Management For added security you can opt to use Access Control based on the MAC address. This feature lets you create a list of MAC addresses that are allowed or denied association with the Router through the wireless interface. When it is enabled, the access point is instructed to forward packets only from wireless devices only if the[...]

56 The remaining connection types (Bridge, Static, DHCP and CLIP) connect upon saving the settings and restarting the Router.
