54GN-A15AG Wireless Access Point User GuideChapter5 TroubleshootingThis chapter gives information about troubleshooting your wireless Access Point. Readthe descriptions below to help you diagnose and solve the problem.Q:What to do if you forget your password or forget the IP address of the AccessPoint?A:Please press the “init” bottom on the Access Point about 5 sec. The Access Point willbe restart and the system setting will restore to the default value.Q:Unable to connect to the Internet?A:1.Please confirm whether or not the power cord is connected properly, and thepower indicating light of the Access Point is normal.2.Please confirm whether or not all of the settings described in this manual areset.3.Please confirm if ADSL or Cable Modem operates properly, and if the ISPnetwork service expires.4.Please confirm if your network cable is connected properly, and the LED statusis normal.Q:What is the IEEE802.11b standard?A:It also referred to as 802.11 High Rate or Wi-Fi. It is an extension to 802.11 thatapplies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5,2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999ratification to the original 802.11 standard, allowing wireless functionalitycomparable to Ethernet.Q:Unable to access the Access Point’s Web Configuration Interface?A:1.Please check the Ethernet connection between the PC and the Access Point iscorrectness.2.Make sure your computer’s IP address is on the same subnet as the AccessPoint.3.Make sure you are using the correct login information.Q:What is WEP?A:Wired Equivalent Privacy. Security mechanism defined within the 802.11 standarddesigned to make the link integrity of the wireless medium equal to wired cable. Dataprivacy mechanism based on a 40 bits (128 bit optional ) shared key algorithm, asdescribed in the IEEE 802.11 standard.
GN-A15AG Wireless Access Point User Guide55Q:What is the IEEE802.11g standard?A:IEEE 802.11g standard specifies data rates of up to 54 Mbits/s in the 2.45-GHzband. It uses orthogonal frequency division multiplexing (OFDM), mandatoryprovisions have been made within the standard to make it inherently compatible withthe well-established 802.11b standard at 11 Mbits/s, which uses complementary codekeying (CCK) modulation. Both .11g and .11b operate at ranges of up to 300 feet.
56GN-A15AG Wireless Access Point User GuideAppendix A: GlossaryAuto-MDI/MDIXOn a network hub or switch, an auto-MDI/MDIX port automatically senses if it needs to actas a MDI or MDIX port. The auto-MDI/MDIX capability eliminates the need for crossovercables.ADSLAsymmetric digital subscriber line (ADSL) is a new modem technology that converts exist-ing twisted-pair telephone lines into access paths for high-speed communications of vari-ous sorts.Auto-negotiateTo automatically determine the correct settings. The term is often used with communica-tions and networking.DHCPThe Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automatingthe configuration of computers that use TCP/IP. DHCP can be used to automatically as-sign IP addresses, to deliver TCP/IP stack configuration parameters such as the subnetmask and default router, and to provide other configuration information such as the ad-dresses for printer, time and news servers.DSSSAlso known as “Direct Sequence Spread Spectrum,” this is a variety of radio transmissionmethods that continuously change frequencies or signal patterns. Direct Sequence SpreadSpectrum (DSSS), which is used in CDMA, multiplies the data bits by a very fast, pseudo-random bit pattern (PN sequence) that “spreads” the data into a large coded stream thattakes the full bandwidth of the channel.Access PointAn access point is a wired controller that sends data to the wireless NICs installed in yournetwork computers, and received data back from them. An AP is often connected to theNetwork computer that has Internet access, or is directly connected to a ADSL or cablemodem.
GN-A15AG Wireless Access Point User Guide57GatewayA device, usually a router, that connects hosts on a local network to other networks.IP AddressEvery machine on the Internet has a unique identifying number, called an IP Address. Atypical IP address looks like this: 216.27.61.137MAC AddressOn a local area network (LAN) or other network, the MAC (Media Access Control) addressis your computer's unique hardware number. Usually written in the form 01:23:45:67:89:abPing (Packet Internet Groper)A utility to determine whether a specific IP address is accessible. It works by sending apacket to the specified address and waiting for a reply. PING is used primarily to trouble-shoot Internet connections.RouterA device that forwards data packets along networks. A router is connected to at least twonetworks, commonly two LANs or WANs or a LAN and its ISP’s network. Routers arelocated at gateways, the places where two or more networks connect.DNSThe Domain Name System (DNS) is a distributed Internet directory service. DNS is usedmostly to translate between domain names and IP addresses, and to control Internet emaildelivery. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot belocated and email delivery stalls.Dynamic IP AddressAn IP address that is automatically assigned to a client station in a TCP/IP network,typically by a DHCP server.FirewallA system designed to prevent unauthorized access to or from a private network. Firewallscan be implemented in both hardware and software, or a combination of both. Firewallsare frequently used to prevent unauthorized Internet users from accessing privatenetworks connected to the Internet, especially intranets. All messages entering or leavingthe intranet pass through the firewall, which examines each message and blocks thosethat do not meet the specified security criteria.
58GN-A15AG Wireless Access Point User GuideWANWide Area Network, a communication network that covers a relatively large geographicarea, consisting of two or more LANs. Broadband communication over the WAN is oftenthrough public networks such as the ADSL or Cable systems, or through leased lines orsatellites. In its most basic definition, the Internet could be considered a WAN.WEPWEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 64/128-bit sharedkey algorithm, as described in the IEEE 802.11 standard.TCP/IPTCP/IP (Transmission Control Protocol/Internet Protocol), the suite of communicationsprotocols used to connect hosts on the Internet.Subnet MaskA mask used to determine what subnet an IP address belongs to. An IP address has twocomponents, the network address and the host address. Subnetting enables the networkadministrator to further divide the host part of the address into two or more subnets.SSIDThe SSID is the name represent the router in the wireless network.
