Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point

•Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded easily, using only your Web browser, and can be upgraded remotely.

•Access Control. The Access Control MAC address filtering feature can ensure that only trusted wireless stations can use the WG102 to gain access to your LAN.

•Simple Configuration. If the default settings are unsuitable, they are easy to change.

•Hidden Mode. The SSID is not broadcast, assuring only clients configured with the correct SSID can connect.

•Configuration Backup. Configuration settings can be backed up to a file and restored.

•Power over Ethernet. Power can be supplied to the WG102 over the Ethernet port from any 802.3af compliant mid-span or end-span source such as the NETGEAR FSM7326P Managed Power over Ethernet Layer 3 managed switch.

•Autosensing Ethernet Connection with Auto Uplink Interface. Connects to 10/100 Mbps IEEE 802.3 Ethernet networks.

•LED Indicators. Power, test, LAN speed, LAN activity, and wireless activity are easily identified.

802.11g Standards-based Wireless Networking

The NETGEAR WG102 ProSafe 802.11g Wireless Access Point provides a bridge between Ethernet wired LANs and 802.11g compatible wireless LAN networks. It provides connectivity between Ethernet wired networks and radio-equipped wireless notebook systems, desktop systems, print servers, and other devices. Additionally, the WG102 supports the following wireless features:

•Distributed coordinated function (CSMA/CA, Back off procedure, ACK procedure, retransmission of unacknowledged frames)

•RTS/CTS handshake

•Beacon generation

•Packet fragmentation and reassembly

•Short or long preamble

•Roaming among access points on the same subnet

Autosensing Ethernet Connections with Auto Uplink

The WG102 can connect to a standard Ethernet network. The LAN interface is autosensing and capable of full-duplex or half-duplex operation.
