4. Select any one SSID checkbox shown on AP Scan Result, and then

click Select.

5. Enter up to three preferred AP MAC addresses on Preferred AP0 /

AP1 / AP2 Mac that station associates them preferentially. Preferred AP0

is the highest priority. These entries are optional.

6. Select Enable Roaming checkbox to enable roaming on station.

This entry is optional.

7. Enter SNR value from 0dB to 100dB on Scan SNR Threshold that

station performs channel scanning if the SNR of received signal from

serving AP is less than (<) this threshold; 35 is default setting.

8. Enter SNR value from 0dB to 100dB on Roaming SNR Threshold

that station triggers roaming from the serving AP to other AP if the SNR of

received signal from serving AP is less than (<) this threshold; 30 is default

setting.

Note:

- Scan SNR Threshold MUST be higher than (>)

9. Specify the duration from 1s to 3600s on Max Scan Interval for

channel scanning; 60s is default setting. CPE device conducts at least one

scanning within this interval.

10. Specify the duration from 1s to 60s on Min Scan Interval for

channel scanning; 10s is default setting. No more than one scanning will be

conducted within this interval. This parameter is to prevent too often channel

scanning from affecting the data transmission.

Note:

- Max Scan Interval MUST be higher than (>)

Min Scan

Interval

11. Enter SNR value from 0dB to 10dB on Scan SNR Fluctuation

Threshold. CPE device perform channel scan when the fluctuation of

received signal level from a serving AP is larger than (>) this value. 5dB is

default setting.

12. Select Roaming Hysteresis checkbox to prevent CPE jumping

between two APs due to the received signal level fluctuation. It is known as

Ping-Pong effect. This entry is optional.

13. Select desired channel(s) on Background Scan Channel. CPE

scan the selected channel if the channel scan for roaming is triggered. If no

any channels are checked in a list, all channels are scanned. This entry is

optional.
