performance.
Illegal channel
:
The AP is configured on an illegal channel for the country.
Allowed channels in the 2.4 GHz and 5 GHz
frequency bands are regulated. For example, in the United States, 802.11 channels are regulated by the FCC. This
message indicates that an illegal channel has been detected for the country configured in the Setup menu (see
Security
:
The AP is using WEP or has no security.
The AP does not have encryption enabled or is using WEP. WEP is a
weak security mechanism and shouldn’t be used.
7.2 AP Locate Function
From the AP Scan Table, select an SSID from the list, and select the
Locate
function key, to open up the Locate function for the
SSID selected.
The Locate function is used to track the physical location of an Access Point. It measures the signal level of the traffic
received from the SSID under test and updates the display every 0.5 seconds.
To use this function, walk around the facility and monitor changes in Signal Level. A strong signal level (-20dBm or
greater) indicates close proximity to the AP under test.
This function can be used with the external directional antenna. Refer to
for information on the MTTplus-900 and WX150 external directional antennas, respectively. Alternatively, it can
be used with the unit’s internal antennas.
For antenna selection, refer to
AP Locate Function
SSID:
Service Set Identifier advertised by the Access Point. The SSID is the logical name used to identify the network.
SSID is configured by the network manager. Occasionally network managers prefer to hide the AP’s SSID for security
reasons. In that case, a blank SSID name or “[hidden]” are displayed instead.
BSSID:
Basic Service Set Identifier for the AP. The BSSID is a 48-bit unique MAC address of the AP’s network interface.
Last RX frame:
The Locate function’s Signal level measurement is based on the Signal level measured on frames
received from the SSID under test. If frames are being received on a continuous basis, this counter displays 0s ago,
meaning that traffic is currently received. If frames are not being received on a continuous basis, this counter displays the
duration since the last frame was received.
Min:
Minimum signal level in dBm detected since the beginning of the test. This is the low watermark level.
Current:
Current signal level in dBm measured updated every 0.5 s.
Max:
Maximum signal level in dBm detected since the beginning of the test. This is the high watermark level.
Audio On:
When the user moves closer to the access point, the unit beeps at a higher frequency as it detects a stronger
signal.
