turned off. Most of these services have corresponding items in one of the menus, but some don't (at
least not directly).
Wireless Devices
The wireless devices header section lists Qual(ity), Signal, Noise, Rate, Freq(uency) Mode, and Link
Information. In client mode, all these fields will contain associated information. In AP mode, less
information is shown, link specific details can be found in the Interfaces -> wpci# -> wireless
configuration-> client list.
The first column lists the wireless device (wpci# or wlan#). This is followed by the specific radio
device.
Quality refers to percentage of packets not retransmitted. This provides a quick indication of how well
or poorly the link is running. A high number of retransmits (low percentage number) indicates a very
poor link. On APs, this column will contain the ESSID name.
The Signal column shows signal strength (client only). This number will be negative.
The Noise column (also a negative number) shows background noise level (limited by the driver and
speed – client only). The difference between signal and noise is the signal to noise ratio (SNR). The
SNR which is easily calculated by looking at the signal and noise numbers gives an indication of how
strong a signal your system hears.
The Rate column (client only) indicates the wireless speed. This number will show you the wireless
(not network) connection speed. The specific speeds that will be displayed here depend on operating
mode (802.11a, 802.11b, 802.11g, and turbo mode for those that support it). These speeds may change
during the course of communications if speed is set to auto in the wireless configuration.
The Freq column shows the frequency the system is transmitting/receiving on.
The Mode will consist of three comma separated fields. The first field indicates mode of operation,
one of ap or sta (for Access Point or Station). The second field shows the configured country code.
The third field shows the frequency operating mode, one of 11a, Ta, 11b, 11/jointfilesconvert/355170/bg, Tg, 11g.
The Link information will provide either the number of associations or the system MAC address.
The Information Bar
The information bar on the bottom of the screen provides at a glance a number of things. It provides a
quick way to logoff. It also provides the CPU load. Finally, the information bar shows you the
firmware you're running.
