Figure 48: Video Gateway connected to "SV-WIFI" access point
If Random Selection of SSID is enabled, the unit remains connected to that access point until the connection
is lost. If Random Selection of SSID is cleared, it disconnects from the access point if it can connect to a
higher-priority access point.
Note: In some cases, "Connected" may appear even if the Video Gateway has not successfully connected to
the network. This usually occurs when the signal is relatively weak, the WiFi antenna is not connected
securely to the unit, or the encryption key is incorrect. In these cases, the
System Summary
screen will list
WiFi as “Unavailable.” If the Video Gateway has an IP address in the System Summary
screen (as in figure
43 on page 48), you can be sure that it is properly connected to the access point. Complete and accurate
information about the Video Gateway's network connections can also be seen in SVMultiClient, in the
Statistics
window. For additional information, please refer to the SVMultiClient User Guide .
Note: If you install a WiFi card when the unit is running, you must restart the unit to access wireless networks.
11. Save the settings to store them permanently (see Saving Configuration Changes , page 156). It is not necessary
to restart the system.
Removing an Access Point from the List
If you do not want the Video Gateway to try to connect to an access point that is in the Configured SSID s list, you
can remove it from the list.


 To remove an access point from the list of Configured SSIDs:
1. In the
WiFi Configuration
screen, in the Configured SSIDs list, delete the SSID of the access point.
2. Click Update , and then save the settings (see Saving Configuration Changes , page 156). It is not necessary to
restart the system.
Turning WiFi Off
You can disable all WiFi services without removing the WiFi card from the USB connector or deleting any SSIDs
from the Configured SSIDs list. If the Video Gateway is configured to function as an access point (see
Configuring
the Unit to Function as an Access Point , page 53), this functionality is also suspended when you disable the WiFi
services.
