When connected to an emulation host, the emulation client unexpectedly suspends network activity.
The WL TE Client monitors the state of the Wireless LAN device and has the ability to suspend network activity.
This is maintained through the Network Support setting within the Emulation parameters. By default the Network Support setting is enabled and serves as a means to determining the state of the Wireless LAN device. It consists of two options, Detect Out-Of-Range and Detect Signal Quality.
Detect Out-Of-Range – By default this option is enabled and serves as a means to determining the state of the Wireless LAN device, including the SSID and whether or not it is associated. In doing so, Telnet will suspend network activity if it detects that the Wireless LAN adapter is not currently associated with an Access Point. Of course network activity will resume after the adapter associates with an Access Point.
Detect Signal Quality – By default this option is not enabled but can allow you to also suspend network activity when the network signal quality drops below a specified level.
Network Support governs both Detect Out-Of-Range and Detect Signal Quality.
If Network Support is disabled, Detect Out-Of-Range and Detect Signal Quality will both be disabled. There have been occasions when less than perfect coverage conditions in a facility warrant disabling Network Support.
RF Dense environment.
Environments where devices experience multiple roaming events.
Intermittent RF connectivity.
AP foot prints that force a device to capitulate between connections.
If coverage conditions aren’t always good, it may be best to disable Network Support (and through association Out-Of-Range checking), and allow the TCP retries to handle any lost network packets.
Network Support can be located and disabled by launching the Wavelink Product Configuration and selecting Emulation Parameters. Once within Emulation Parameters, select Emulation and navigate to the Network directory. Network Support, Detect Out-Of-Range and Detect Signal Quality are located within.
