Wi-Fi
5. (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:

(config network wifi client new_client)>
iii. Set the client certificate by using the client_cert paramater and
pasting the certificte in PEM format:
(config network wifi client new_client)> ssid 0
encryption client_cert certificate
(config network wifi client new_client)>
iv. Set the private key by using the private_key paramater and pasting
the private key in PEM format:
(config network wifi client new_client)> ssid 0
encryption private_key key
(config network wifi client new_client)>
v. (Optional) Set the private key passphrase:
(config network wifi client new_client)> ssid 0
encryption private_key_passphrase passphrase
(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.
