Are you using different SSID for the networks?

Yes, if you were using ap_scan=1 mode..

This is not a valid configuration line.

This makes the driver select which network to use. As long as you are
using different SSIDs in the networks, this should be enough. Actually,
I would expect the NDIS driver to select the WPA-enabled network
automatically even if the SSIDs were same.

The correct format for BSSID would be 00:0D:54:FC:70:18. However, this
is unlikely to be used with ap_scan=2 mode.

With ndiswrapper and NDIS drivers, wpa_supplicant has a bit less control
on which AP will be used. In practice, it is up to the NDIS driver to
decide what to do.
