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:
n
n
n
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:
(config network wifi client new_client)> bgscan_short_interval value
(config network wifi client new_client)>
where value is any integer greater than 0. The default is 1.
d. 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 greater than
the value of bgscan_strength:
(config network wifi client new_client)> bgscan_long_interval value
(config network wifi client new_client)>
where value is any integer greater than 0. The default is 1.
e. Configure the frequencies that will be scanned for available access points.
The IX20W device has three preconfigured frequencies:
n
n
n
You can delete the preconfigured frequencies and add additional frequencies. At least one
frequencies is required.
f. To delete a preconfigured frequencies:
i. Use the show command to determine the index number of the channel to be deleted:
(config network wifi client new_client)> show background_scanning
scan_freq
0 2412
1 2437
2 2462
(config network wifi client new_client)>
IX20 User Guide
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.
