Different wireless network instances have been configured for a mobile thin client. The thin client should switch over to the strongest network automatically.
Parameters to configure WiFi roaming options can be found in the IGEL registry (Setup > System > Registry). These settings should be changed by experts only.
- Parameters for better control of WiFi roaming capabilities with access points that share the same SSID:
truethe device will stick to the access point it is connected to even if candidates with better signal quality are present.
Setting this parameter to
trueis a last resort for problems that are caused by too much roaming.
Only active with encryption methods WPA Enterprise and WPA2 Enterprise.
none: No background scanning is done.
simple: The WiFi module tries to scan for a potentially better signal in the background.
simpleprovides following options:
This defines a threshold that determines which of the following two parameters shall be effective.
Interval between background scans (in seconds) if the actual signal level of the currently connected access point is worse than signal_strength.
Interval between background scans (in seconds) if the actual signal level of the currently connected access point is better than signal_strength.If parameter lock_initial is
true, it is recommended to set bgscan.module to
- Parameters to control WiFi roaming between WiFi networks with different SSIDs:
The interval in seconds between checking if automatic roaming might be neccessary.
This includes detecting that a connection has been lost and a new one should be established.
If the current connection's quality percentage is below this value
scanning will be performed to find a potentially better network.
A candidate for automatic roaming is only considered if its quality percentage
is this much better than the current connection's quality.
During boot: If the previously used SSID's quality percentage is above this threshold it is preferred.
If true, the user can initiate roaming to a network via the WiFi tray icon's context menu (must be enabled).
If automatic roaming shall not interfere with the user's choice, the following values are appropriate:
