There is no way to set the value of SecurityEnabled using the OBiTalk portal,
or the local webpage UI. However, connecting locally and browsing to
http://obiconnect.com/wifi brings up the "OBiWiFi" configuration page.
Using that tool to add a network (i.e SSID and WPA2 password) does produce a configuration
(visible from the local webpage UI) where the entries for both Access Point 1 and Access Point 2 are
populated, and each show SecurityEnabled as Yes. And in fact a connection is made to the AP2 network.
However, the tool also sets the value of PreferredAccessPoint to Access Point 2.
If I use the webpage UI to set the value of PreferredAccessPoint to None, then power cycle the router,
the entries for Access Point 2 are all erased!
My current guess is that setting wifi values using the local webpage UI is not a good idea.
The dedicated
obiconnect.com/wifi page seems to be the safe way to go.
