/. Active channel and signal strength is shown in the printer’s display 

window when the <i> key is pressed.

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.

 

Transmits current channel.

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”.

Transmits the MAC address of the associated access point.

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).

Transmits signal strength.

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).
