That's odd, because it should be sending out a probe request anyway,
getting the probe response with the IE back, and updating it's scan
table.  At least, that's the way it's reasonable to expect that it would
work.  I wouldn't expect it to ignore the scan_ssid=1 just because the
network block doesn't match, because then what's the point of the
scan_ssid=1 anyway...

I assume you're not specifying the BSSID in the network block?
