/. Active channel and signal strength is shown in the printer's display
3
window when the <i> key is pressed.

Active Channel

802.11b/g operates on a number of different channels, corresponding
to different frequencies. The printer scans for a suitable access point and
channel. The selected channel can be read from the printer. The read-
only setup-variable "CHANNEL" can assume values from 0 up to 14
depending on the region setting. 0 signifies that an association has not
yet been made, 1-14 is the currently selected channel.
<STX><SI>wt,CHANNEL<ETX>
Transmits current channel.

Access Point Information

The printer associates with an access point. The read-only setup-variable
"AP_MAC" will assume the MAC address of the access point which the
printer is currently associated with. If no association has been performed,
the value of "AP_MAC" is "00:00:00:00:00:00".
<STX><SI>wt,AP_MAC<ETX>
Transmits the MAC address of the associated access point.

Signal Strength

An important tool when working out problems with wireless LANs
is a signal strength meter. The printer monitors the received signal
strength, and makes it available to the user. The read-only setup variable
"SIGNAL" assumes the value of the current received signal strength. The
value may vary from 0 (no signal) to 100 (maximum strength).
<STX><SI>wt,SIGNAL<ETX>
Transmits signal strength.

Speed

Depending on different (radio) network parameters—such as distribu-
tion of access points, frequencies, number of clients, etc.—the network
card may select a lower speed than the maximum for better overall per-
formance. The selected speed (rounded down to whole Mbps) can be
read from the printer. The read-only setup-variable "SPEED" can assume
values from 0 up to 54 (Mbps).
