  • Page 8: Introduction

    Congratulations on your purchase of the RangeLAN802 Access Point, a member of the RangeLAN802 family, Proxim’s IEEE 802.11-compliant wireless LAN products. Proxim has long been a leader in wireless networking and is excited to introduce IEEE 802.11 products. RangeLAN802 Access Point was designed to be a “plug-and-play” product. In many cases, you will not even need to run any software to configure it.
  • Page 9: The Rangelan802 Family

    The RangeLAN802 Family The RangeLAN802 Access Point is part of a family of high-performance products that provides a complete wireless networking solution. RangeLAN802 8401 is a 100 mW wireless LAN adapter which fits into a PC Card (PCMCIA) Type II slot on a portable notebook, laptop or pen-based computer.

  • Page 12: Quick Installation

    2. Quick Installation You may follow the quick installation steps if the following conditions are true: There will only be one Access Point on this network; You will use all the software default values; You do not need to configure an IP address for the Access Point and do not intend to manage it via telnet or a Web browser;...
  • Page 13 Figure 2 Attachment of the RangeLAN802 Access Point Antenna 2. Attach an Ethernet cable to the Ethernet port on the back of the RangeLAN802 Access Point. 3. Plug the power cable into the back of the RangeLAN802 Access Point and into an AC power outlet. Since there is no On/Off switch on the Access Point box, the unit will turn on as soon as power is applied.
  • Page 14: Installation

    Antenna Options The RangeLAN802 Access Point is shipped with a standard directly-connected antenna. To install the antenna, screw it clockwise onto the antenna connector. Proxim sells several antenna alternatives including higher gain and directional antennas. Each of these antennas ships with installation and mounting instructions. For information on...
  • Page 15: Mounting Options

    Also, Proxim recommends that the Access Point be mounted vertically in installations with extreme ambient temperatures. In addition, Proxim offers an optional Outdoor Enclosure (shown without the lid at- tached in Figure 5, below) for installations which afford little or no protection against the elements and where the ambient temperature exceeds the operating temperature specifi- cation of the Access Point, as described in Appendix F.

  • Page 18: Wireless Topologies

    4. Wireless Topologies RangeLAN802 products look and operate similar to Ethernet products. The only difference is that a radio replaces the wire between various nodes. This means that all of your existing applications that operate over Ethernet will work with RangeLAN802 without any special wireless networking software.
  • Page 19: Infrastructure Network

    Infrastructure Network Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by attaching an Access Point to the wired LAN. This allows the wireless clients to access the network re- sources.

  • Page 22: Configuration

    5. Configuration You need to configure the RangeLAN802 Access Point if: There is more than one RangeLAN802 Access Point on this network, for example in a roaming environment; You need to change the software default values, including IP address; You want to set ESSID on your network; or You want to enable Security and set an Encryption Key on your network.
  • Page 23: Remotely (In-Band)

    1. Connect the null modem RS-232 cable between the RangeLAN802 Access Point Local Management Port and a free serial port on your terminal or PC. 2. Configure the terminal or terminal emulation package for 9600 bps, no parity, 8 data bits, and 1 stop bit. If you are using a terminal emulation package, choose TTY as the terminal type.
  • Page 24: Modem Support

    Modem Support The RangeLAN802 Access Point may be remotely configured via a dial-up modem. To allow for this type of configuration: 1. Configure the modem from a terminal or terminal emulation program at 9600 bps. 2. Issue the following commands to the modem: (Auto-answer after 1 ring) ATS0=1 (Ignore DTR)

  • Page 28: Tcp/Ip Configuration Menu

    TCP/IP Configuration Menu Use this option to change the TCP/IP parameters of the RangeLAN802 Access Point. t l u IP Address indicates the IP address that will be assigned to the RangeLAN802 Access Point. It must be a unique address on the network. This parameter will not change until the Access Point is reset.
  • Page 29: Filter Configuration Menu

    Subnet Mask indicates the mask that will be used to determine what network the RangeLAN802 Access Point is on. This parameter will not change until the Access Point is reset. If a packet generated by the Access Point is destined for an IP host or node belonging to a different IP subnet, the RangeLAN802 Access Point will send this IP packet to the Default Gateway (usually a router) so that the packet can be routed to the proper desti- nation.
  • Page 31 The Protocol Type Filters prevent traffic of a particular protocol type from being forwarded from Ethernet to RangeLAN802. When “Other Types” is enabled, all types other than those listed will be filtered out. DO NOT filter out the types of packets you know RangeLAN802 nodes will need to receive.

  • Page 33 This option allows you to change the various wireless parameters. The Radio Port Administrative Status is for SNMP usage. It corresponds to the SNMP MIB-II Administrative status parameter and can be used to bring the radio inter- face back up after it has been disabled by an SNMP manager. The Delay Radio Reconfigure parameter allows you to delay radio parameter changes from taking effect.
  • Page 34: Ethernet Configuration Menu

    The Hopping Pattern defines a hopping sequence as specified in the IEEE 802.11 specification. All Access Points in a roaming environment must have a unique Hopping Pattern. For a compatibility table between Proxim's RangeLAN802 Hopping Pattern and other IEEE 802.11 products’ Set and Patterns, see Appendix E.
  • Page 35: Authorization Table

    Note that clients configured to use “Any” ESSID may continue to associate with the non-functional Access Point. Therefore, Proxim recommends that all wireless clients be manually configured with an ESSID and that customers avoid using the “Any” option if the 10BaseT Link Monitor has been enabled on an Access Point.
  • Page 36: Upload Configuration Menu

    This feature allows you to upload the current configuration of an Access Point on the network to a file on an FTP server. A member of the Proxim Technical Support Depart- ment may ask you to create this file for troubleshooting purposes.

    Radio Statistics Menu This menu displays the number of successfully transmitted and received packets through the radio interface of the RangeLAN802 Access Point. The WEP ICV Errors statistic counts the number of frames whose received Integrity Check Value (ICV) does not match the calculated value. An ICV is a checksum for an encrypted packet, distinct from the frame checksum.
  • Page 40: Ethernet Statistics Menu

    Ethernet Statistics Menu This menu displays various statistics about Ethernet traffic to and from the RangeLAN802 Access Point. Bridge Statistics Menu This menu displays information regarding packets that were filtered due to the bridge’s learning about the location of nodes. It also shows the percentage of the bridge’s for- warding table that is used up by learned node addresses.

    The Read/Write SNMP Community parameter specifies a community sup- ported by the RangeLAN802 Access Point. Actions permitted by this commu- nity are “read-write” (GET, GET-NEXT, and SET). The Read/Write SNMP Manager IP Address specifies the IP address of the SNMP manager which is permitted to use the Read/Write SNMP Community. An address of 0.0.0.0 indicates any manager may use the community.
