[. . . ] Try the following troubleshooting steps. · Check whether other computers work. If they do, ensure that your computer's TCP/IP settings are correct. If using a fixed (Static) IP Address, check the Subnet Mask, Default Gateway, DNS, and IP Addresses. If the computers are configured correctly, but still not working, ensure that the WPN802 is connected and turned on. If you cannot connect to it, check the LAN and power connections. Troubleshooting 202-10101-01, May 2005 · 6-2 Reference Manual for the NETGEAR RangeMaxTM Wireless Access Point WPN802 · · · · If the WPN802 is configured correctly, check your Internet connection (DSL/Cable modem, etc. ) to make sure that it is working. When entering configuration settings, be sure to click the Apply button before moving to another menu or tab, or your changes are lost. Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration. Using the Reset Button to Restore Factory Default Settings The reset button on the rear panel of the WPN802 has two functions: · · Reboot: When pressed and released quickly, the WPN802 will reboot (restart). Reset to Factory Defaults: This button can also be used to clear ALL data and restore ALL settings to the factory default values. These settings are shown in "Default Factory Settings" on page 3-1. To clear all data and restore the factory default values: 1. Power off the WPN802 and power it back on. Use something with a small point, such as a pen, to press the reset button in and hold it in for at least five seconds. The factory default configuration has now been restored, and the WPN802 is ready for use.

Wireless Networking Overview The WPN802 Access Point conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802. 11b and 802. 11g standards for wireless LANs (WLANs). On an 802. 11b or g wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2. 5GHz. The maximum data rate for the 802. 11b wireless link is 11 Mbps, but it will automatically back down from 11 Mbps to 5. 5, 2, and 1 Mbps when the radio signal is weak or when interference is detected. The 802. 11g auto rate sensing rates are 1, 2, 5. 5, 6, 9, 12, 18, 24, 36, 48, 54, and 108 Mbps. The 802. 11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet Compatibility Alliance (WECA, see http://www. wi-fi. net), an industry standard group promoting interoperability among 802. 11 devices. The 802. 11 standard offers two methods for configuring a wireless network - ad hoc and infrastructure. Infrastructure Mode With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This mode provides wireless connectivity to multiple wireless network devices within a fixed range or area of coverage, interacting with wireless nodes via an antenna. In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. [. . . ] But, using TKIP, WPA-PSK automatically changes the keys at a preset time interval, making it much more difficult for hackers to find and exploit them. The Wi-Fi Alliance will call this, 'WPA-Personal. ' Wi-Fi Protected Access and IEEE 802. 11i Comparison Wi-Fi Protected Access will be forward-compatible with the IEEE 802. 11i security specification currently under development by the IEEE. Wi-Fi Protected Access is a subset of the current 802. 11i draft, taking certain pieces of the 802. 11i draft that are ready to bring to market today, such as its implementation of 802. 1x and TKIP. These features can also be enabled on most existing Wi-Fi CERTIFIED products as a software upgrade. [. . . ]
