These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Channel The Wireless Channel sets the radio frequency used for communication. ¡EAccess Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. ¡E In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) ¡E If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. CAUTION: 1) To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons. 2) This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 27 Appendix B Troubleshooting Overview This chapter covers some common problems that may be encountered while using the HomePlug 802.11g Access Point and some possible solutions to them. If you follow the suggested steps and the HomePlug 802.11g Access Point still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the HomePlug 802.11g Access Point to configure it. Solution 1: If you don't know the Wireless settings of the HomePlug 802.11g Access Point, you must use the HomePlug interface for configuration.

The Windows utility is able to locate the HomePlug 802.11g Access Point even if its IP address is incompatible with your PC, or your PC and the HomePlug 802.11g Access Point are using different HomePlug network passwords. Problem 2: My PC's wireless interface can't connect to the HomePlug 802.11g Access Point. Solution 2 Check the following: • The SSID and wireless security settings on the PC match the settings on the HomePlug 802.11g Access Point. Note that if the SSID (network name) is not broadcast, you will not be able to see the HomePlug 802.11g Access Point in your PC's list of "Available Networks", so will not be able to select it. Instead, you must configure the network details manually. • On the PC, the wireless mode is set to "Infrastructure" Problem 3: My PC's HomePlug interface can't connect to the HomePlug 802.11g Access Point. Solution 3 Check that your PC and the HomePlug 802.11g Access Point are using the same HomePlug network password. 28 Appendix C Windows TCP/IP Overview Normally, no changes need to be made to your Network. Adding the HomePlug 802.11g Access Point does not change your network. • By default, the HomePlug 802.11g Access Point will act as a DHCP client, automatically obtaining a suitable IP Address (and related information) from your DHCP Server. • If you don't have a DHCP Server on your LAN, you should use fixed (static) IP addresses on each PC. • If using Fixed (specified) IP addresses on your LAN (instead of a DHCP Server), there is no need to change the TCP/IP of each PC. Just configure the HomePlug 802.11g Access Point to match your existing LAN. The following sections provide details about checking the TCP/IP settings for various types of Windows, should that be necessary. Checking TCP/IP Settings - Windows 9x/ME: 1.
