Different wireless network instances have been configured for a mobile device. The device should switch over to the strongest network automatically.
Parameters to configure Wi-Fi 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 Wi-Fi roaming capabilities with access points that share the same SSID:
true, the 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 Wi-Fi 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 Wi-Fi roaming between Wi-Fi 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.
true, the user can initiate roaming to a network via the Wi-Fi tray icon's context menu (must be enabled).
If automatic roaming shall not interfere with the user's choice, the following values are appropriate:
