Select this option to keep your AP’s SSID private. Only users who
explicitly enter the SSID name in their connection window while con-
necting will be able to “see” it.

Wireless
Mode
This displays a list of available wireless modes. As of this writing, the
N220 only supports 2.4 GHz.
N220 only supports 2.4 GHz.
Channel
Select a channel on which on broadcast your AP’s wireless signal.
If there are a high number of APs broadcast within range of one
another, try to use a channel that is either not in use or that has the
fewest number of broadcasters. Too many APs using the same channel
can interfere with one another.

Output
Power
Set this field if you need to conserve power consumption (especially for
notebook computers). This control changes the strength of the N220’s
antenna gain or transmission power. Antenna gain, listed here as a per-
centage, is the increase in coverage. Higher antenna gain improves the
range of the signal for better communications.
• 100% - Sets the antenna gain at maximum output power. This has
notebook computers). This control changes the strength of the N220’s
antenna gain or transmission power. Antenna gain, listed here as a per-
centage, is the increase in coverage. Higher antenna gain improves the
range of the signal for better communications.
• 100% - Sets the antenna gain at maximum output power. This has
the highest level of power consumption. If you are using the N220 on
a notebook computer running on battery power, then using this
power setting will drain the battery the fastest.
• 75% - Sets the antenna gain to medium-high output power. This is
a decent comprimise between signal strength and power consump-
tion.
• 50% - Sets the antenna gain to medium output power. The range is
reduced but the power consumption is much less.
• 25% - Sets the antenna gain to low output power. This significantly
reduces the transmission range but save considerable power.
• Lowest - Sets the antenna gain to minimal output power. You are
trading decent transmission range for significant power savings.
Bridge

(NIC)) on your computer from the drop-down list box. This allows you
to connect your wireless network to the specified wired network.
