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.
Channel
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).
