ProSafe Wireless-N Access Point WNAP320 Reference Manual Table 6. Basic Wireless Settings (Continued) Field 11ng mode only (continued) Descriptions Ext Channel Offset When you select a channel width of Dynamic 20/40 MHz or 40 MHz, you also need to select the offset for the extension channel from the Ext Channel Offset drop-down list. In addition to the default value Auto, you can also select Upper or Lower. 11b and 11bg modes only Output Power Guard Interval From the drop-down list, select the guard interval to protect transmissions from interference. In addition to the default value Auto, you can also select Long - 800 ns. Some legacy devices can operate only with a long guard interval. Data Rate From the drop-down list, select the transmit data rate of the wireless network. The default setting is Best. For a list of all options that you can select from in 11b mode and 11bg mode, see Factory Default Settings in Appendix A. From the drop-down list, select the transmission power of the wireless access point. The default is Full. Note: Increasing the power improves performance, but if two or more wireless access points are operating in the same area, on the same channel, it can cause interference. Channel Bonding Note: Make sure that you comply with the regulatory requirements for total radio frequency (RF) output power in your country. This drop-down list lets you to specify channels to bond. The available options are 20 MHz, 20/40 MHz, and 40 MHz. 3. If you have changed the wireless mode and selected the Turn Radio On check box, a popup window appears: click OK to confirm your change. 4. Click Apply to save your settings. You should not need to change the operating frequency (channel) unless you notice interference problems, or are setting up the wireless access point near another wireless access point. Observe the following guidelines: • Wireless access points use a fixed channel. You can select a channel that provides the least interference and best performance. In the United States and Canada, 11 channels are available. • If you are using multiple wireless access points, it is better if adjacent wireless access points use different channels to reduce interference. The recommended channel spacing between adjacent wireless access points is 5 channels (for example, use channels 1 and 6, or 6 and 11). • In infrastructure mode, wireless stations normally scan all channels, looking for a wireless access point. If more than one wireless access point can be used, the one with the strongest signal is used. This can happen only when the wireless access points use the same SSID. The WNAP320 wireless access point functions in infrastructure mode by default. 26 | Chapter 2. Installation and Basic Configuration
