    It will allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. By default he DSL-G604T broadcasts its SSID so that any wireless station in range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless environment for access points.
  • Page 17: About 802.11G Wireless

    About 802.11g Wireless Today's 11-megabits-per-second 802.11b wireless networks are fine for broadband Internet access (which typically tops out at about 1 mbps) but rather slow for large internal file transfers or streaming video. However, 54-mbps, corporate-oriented 802.11a is expensive--and because its radio uses the 5-GHz band and 802.11b uses the 2.4-GHz band, upgrading to an 802.11a network means either scrapping 802.11b gear or buying even-pricier hardware that can support both standards.

The bits of the subnet mask correspond directly to the bits of the IP address.
  • Page 78: Microfilters And Splitters

    Microfilters and Splitters Most ADSL clients will be required to install a simple device that prevents the ADSL line from interfering with regular telephone services. These devices are commonly referred to as microfilters or sometimes called (inaccurately) line splitters. They are easy to install and use standard telephone connectors and cable. Some ADSL service providers will send a telecommunications technician to modify the telephone line, usually at the point where the telephone line enters the building.
  • Page 79 Line Splitter If you are instructed to use a “line splitter”, you must install the device between the Router and the phone jack. Use standard telephone cable with standard RJ-11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the Router and if desired, a telephone or telephone device.
