WIRELESS
Signal (%) This field displays the signal strength of the target
wireless network, as received by the CGNV2, as a
percentage fro 0 (no reception) to 100 (perfect
reception)
W-mode This field displays the wireless network standard (for
instance, 11n) that the target wireless network is using.
ExtCH For IEEE 802.11n networks that support 40MHz
wireless transmissions, this field displays whether the
network uses channel bonding, and specifies whether
the extension channel is above or below the primary
control channel.
NOTE: Channel bonding allows an access point to
increase data throughput by using two wireless
channels simultaneously, instead of a single
channel. When you use channel bonding, you
have a primary control channel, and an
extension channel. The extension channel may
be either directly above the control channel, or
directly below.

For IEEE 802.11n networks using channel bonding,
where the extension channel is above the main
channel,
ABOVE displays.

For IEEE 802.11n networks using channel bonding,
where the extension channel is above the main
channel,
BELOW displays.

For networks that do not use channel bonding,
NONE displays.
