Au contraire! These are popular test devices here in DTS, so I upgraded one (of the three!) that I have lying around to 9.2.1 (-: Running the same test that I described yesterday, it worked as expected.
2016-01-21 10:44:10.552 CaptiveTest[236:6500] en0: CNCopyCurrentNetworkInfo returned {
BSSID = "xx:xx:xx:xx:xx:xx";
SSID = QuinnNet;
SSIDDATA = <5175696e 6e4e6574>;
}
I have no idea what's causing the failure in your environment but I think the usual debugging steps apply:
1. Make an encrypted backup of the device (you want an encrypted backup so that it saves the keychain).
2. Restore that backup to a similar device. If the problem follows the backup, you're in luck because a) if worst comes to worst, you have something to submit in a bug report, and b) you can perform the next steps and still get back to where you started from.
3. On the original device, reset your network settings; do you still have the problem?
4. On the original device, reset /all/ your settings; do you still have the problem?
5. On the original device, restore the OS; do you still have the problem?
... and so on.
Share and Enjoy
