[. . . ] This is done to bring a computer back onto the network after moving it to a different location, or after experiencing an unexpected outage. Computers on DHCP networks often (but not always) re-establish network connectivity automatically. 14 EN · Site Survey Selecting the Site Survey tab displays a list of available wireless network access points. It shows you the following information: · Network type shows the network setup · The name of the wireless connection (Network Name, or SSID) · Network mode shows which WIFI standard is used · An icon reflecting if encryption is enabled · Signal strength · Channel that is used by the network · MAC address of the device Double-click one of the network names to open the Profile Wizard for establishing a wireless connection with that network. · Version information Selecting this tab displays vendor and version information. 15 EN Network terminology Read this chapter if you want to know how to interpret the terminology used in this manual. A network provides a means of communication between two or more computers (and other devices) that are connected to each other through wired or wireless means. WIRED At each computer, you will need a network adapter or Network Interface Card (NIC) to be able to connect the computer to the network cable. Examples are: Ethernet cable Ethernet notebook adapter Already built-in ETHERNET WIRELESS At each computer, you will need to install a WiFi wireless adapter to be able to connect to another wireless enabled device. Examples are: Wireless USB adapter Wireless notebook adapter 11g Already built-in 16 EN In a network, the computers need to be able to connect to each other physically. Therefore, another important network property is how the computers connect to each other, either directly or through a central device. 2 PCs) NOTE: Use a crossover Ethernet cable to connect two computers directly to each other. WIRED NETWORK WITH MORE THAN 2 PCs Use a hub or switch to connect more than 2 PCs to each other. NOTE: Use straight-through Ethernet cables to connect the computers to the central device (hub/switch). HOW TO INTERCONNECT WIRED NETWORKS Use a gateway router to connect one network to another (e. g. to the Internet, also known as WAN). ONE-ON-ONE WIRELESS NETWORK Also known as: Ad Hoc / Peer-to-Peer WIRELESS NETWORK WITH MORE THAN 2 PCs Also known as: Ad Hoc / Peer-to-Peer The wireless medium forms a hub in and of itself. No hardware hub is needed. CONNECTING WIRELESS TO WIRED NETWORKS also known as: Infrastructure / Access Point Use a wireless base station. Central devices, like a hub, switch, router or wireless access point may be standalone devices or built into a computer. · A hub has multiple ports and serves as a central connection point for communication lines from all computers on a wired network. A switch is similar to a hub, but is able to handle different network speeds at each port. · Gateway routers and wireless access points route network traffic from one network to another (e. g. from a wired network to the Internet, or from a wireless network to a wired network or to the Internet). 17 EN Glossary of terms DHCP ­ Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP settings of every computer on your home network. DNS Server Address ­ DNS stands for Domain Name System, which allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a domain name is requested, the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. [. . . ] Service unavailable. Check that you have enabled and configured the service correctly. If you cannot connect to a particular server, be sure that you have access rights and a valid ID and password. If you cannot access the Internet, be sure you have configured your system for TCP/IP. Make sure the access point that the station is associated with is powered on. [. . . ]
