6. (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. Enable background scanning:
(config network wifi client new_client)> background_scanning enable
true
(config network wifi client new_client)>
b. Set the scan threshold (bgscan_strength), in dB, that is used to determine the scanning
frequency.
(config network wifi client new_client)> bgscan_strength value
(config network wifi client new_client)>
where value is an integer between -113 and 0.
The scan threshold works with the short and long intervals (bgscan_short_interval and
bgscan_long_interval) to determine how often the device should scan for available
access points:

c. Set 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
value of bgscan_strength:

wpa2:
i. Set the username that the client will use to connect to the access point:
(config network wifi client new_client)> ssid 0 encryption
id_wpa2 username
(config network wifi client new_client)>
ii. Set the password that the client will use to connect to the access point:
(config network wifi client new_client)> ssid 0 encryption
password_wpa2 pwd
(config network wifi client new_client)>
If the signal strength from the access point to which the client is currently
connected is below the value of bgscan_strength, it will use bgscan_short_
interval to determine how often to scan for available access points.
If the signal strength from the access point to which the client is currently
connected is stronger than the value of bgscan_strength, it will use bgscan_long_
interval to determine how often to scan for available access points.
If bgscan_short_interval and bgscan_long_interval are set to the same value,
bgscan_strength is ignored. For example, the default configuration has both
bgscan_short_interval and bgscan_long_interval set to 1 second, which means
that the device will scan for access points once per second regardless of the value
of bgscan_strength.
