Description

Channel	Shows the channel on which the access point is currently broadcasting.
	The Channel defines the portion of the radio spectrum that the radio uses for
	transmitting and receiving.
	The channel is set on the Advanced menu’s Radio Settings page. (See “Radio”
	on page 129.)

Signal	Indicates the strength of the radio signal emitting from this access point as
	measured in decibels (Db).

# of Beacons	Shows the total number of beacons transmitted by this access point since the
	access point was last booted.

Last Beacon	Shows the date and time of the most recent beacon transmission from the
	access point.

Rates	Shows supported and basic (advertised) rate sets for the neighbouring access
	point. Rates are shown in megabits per second (Mbps).
	All supported rates are listed, with basic rates shown in bold.
	Rate sets are configured on the Advanced menu’s Radio Settings page. (See
	“Radio” on page 129.) The rates shown for an access point will always be the
	rates currently specified for that access point in its radio settings.
