The roaming table

The roaming table contains various threshold values which control the behavior of the WLAN device when it is roaming in the 'Client' operating mode.





LANconfig: Wireless LAN > General > Extended settings > Expert WLAN settings > Roaming

Command line: Setup > Interfaces > WLAN > Roaming

Enable soft roaming
With this option enabled, a client uses scan information to roam to a stronger AP (soft roaming). Roaming due to connection loss (hard roaming) is unaffected by this. The roaming threshold values only take effect when soft roaming is activated.
Beacon miss threshold
The beacon loss threshold defines how many AP beacons can be missed before a registered client starts searching again. Higher values will delay the recognition of an interrupted connection, so a longer time period will pass before the connection is re-established. The lower the value set here, the sooner a potential interruption to the connection will be recognized; the client can start searching for an alternative AP sooner.
Important: Values which are too small may cause the client to detect lost connections more often than necessary.
Roaming threshold
This value is the percentage difference in signal strength between access points above which the client will switch to the stronger AP.
Note: Other contexts require the value of signal strengths in dB. The following conversion applies:

64dB – 100%

32dB – 50%

0dB – 0%

No roaming threshold
This threshold refers to the field strength in percent. Field strengths exceeding the value set here are considered to be so good that no switching to another AP takes place.
Force roaming threshold
This threshold refers to the field strength in percent. Field strengths below the value set here are considered to be so poor that a switch to another AP is required.
Connect threshold
This value defines field strength in percent defining the minimum that an AP has to show for a client to attempt to associate with it.
Connect hold threshold:
This threshold defines field strength in percent. A connection to an AP with field strength below this value is considered as lost.
Min. connect signal level
Similar to the connect threshold, but specified as absolute signal strength.
Min. connect hold signal level
Similar to the connection hold threshold, but specified as absolute signal strength.
Block time
If your device is operating as a WLAN client in an environment with multiple WLAN access points all with the same SSID, you can define a time period during which the WLAN client will avoid associating with a particular AP after receiving an "association-reject" from it. Possible values are 0 to 4294967295 seconds. The default value is 0 seconds. Client authentication is not blocked.
