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:
Command line:
- 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.
