The roaming table contains various threshold values which influence the precise control over the LANCOM Wireless Router's behavior when roaming in the 'Client' operating mode.
LANconfig: Wireless LAN / Expert WLAN settings / Roaming
WEBconfig: LCOS menu tree / Setup / Interfaces / WLAN / Roaming
- Soft roaming This option enables a client to use scan information to roam to the strongest access point (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 This defines how many access-point beacons can be missed before
an associated 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 smaller the value set here, the sooner a potential
interruption to the connection will be recognized; the client can start searching for an
alternative access point sooner.
Note: 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 access
point.
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 access point will take place.
- Forced 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 access point is required.
- Connect threshold This value defines field strength in percent defining the minimum that an access point 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 access point with field strength below this value is considered as lost.
