Operating Frequency (Channel) Guidelines
You should not need to change the operating frequency (channel) unless you notice
interference problems, or are setting up the wireless VPN firewall near another wireless
access point. Observe the following guidelines:
• Wire
less 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 a
vailable.
• 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 in
frastructure mode, wireless devices 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 FVS318N wireless VPN firewall functions in infrastructure mode by
default.

smit power that you select, the

displayed in the Transmit Power field.
