4 Wireless Modifying Virtual Access Point Settings Table 10 Radio Settings Field Descriptions Field Channel Description Select the Channel. NOTE: If Radio Interface is set to Off, the Channel cannot be changed. The range of available channels is determined by the mode of the wireless radio interface and the country code setting. If you select Auto for the channel setting, the access point scans all available channels, immediately selects a channel, and begins operation. If interference or errors occur on that channel, another channel is automatically selected. The Channel defines the portion of the wireless radio spectrum the wireless radio uses for transmitting and receiving. Each mode offers a number of channels, depending on how the spectrum is licensed by national and transnational authorities such as the Federal Communications Commission (FCC) or the International Telecommunication Union (ITU-R). NOTE After you configure the wireless settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the access point to stop and restart system processes. If this happens, wireless clients temporarily lose connectivity. We recommend that you change access point settings when WLAN traffic is low. Modifying Virtual Access Point Settings To change VAP 0 or to enable and configure additional VAPs, select the Virtual Access Points (SSIDs) tab in the Wireless section. VAPs segment the wireless LAN into multiple broadcast domains that are the wireless equivalent of Ethernet VLANs. VAPs simulate multiple access points in one physical access point. The Cisco AP 541N supports up to 16 VAPs. 55 Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide
