7. (Optional) Configure Background scanning .
Background scanning allows the device to scan for nearby access points and to move between
access points that have the same SSID that is configured for the client connection, based on
the signal strength of the access points.
a. Click to expand Background scanning .
b. Click Enable background scanning to enable.
c. For Scan threshold , enter a value in dB that is used to determine the scanning frequency.
The allowed value is an integer between- 113 and 0 .
The Scan threshold works with the Short interval and Long interval options to
determine how often the device should scan for available access points:
n
If the signal strength from the access point to which the client is currently
connected is below the
Scan threshold , it will use the Short interval to determine
how often to scan for available access points.
n
If the signal strength from the access point to which the client is currently
connected is stronger the
Scan threshold , it will use the Long interval to
determine how often to scan for available access points.
n
If Short interval and Long interval are set to the same value, Scan threshold is
ignored. For example, the default configuration has both Short interval and Long
interval set to 1 second, which means that the device will scan for access points
once per second regardless of the Scan threshold .
d. For Short interval , type the number of seconds to wait between scans for access points,
when the signal strength from the access point to which the client is currently connected is
below the
Scan threshold .
e. For Long interval , type the number of seconds to wait between scans for access points,
when the signal strength from the access point to which the client is currently connected is
stronger than the
Scan threshold .
f. Click to expand Scan frequencies list .
The TX54 device has three preconfigured channels that will be scanned for available
access points:
n
Channel 1 (2412 MHz)
n
Channel 6 (2437 MHz)
n
Channel 11 (2462 MHz)
You can delete the preconfigured channels and add additional channels. At least one
channel is required.
g. To delete a preconfigured channel, click the menu icon ( ... ) next to the channel and select
Delete .
