Comment 40 for bug 1542733

I've just done a fresh install today of 16.04.2 which has network manager version 1.2.2. Once the updates are completed the network manager has been upgraded to version 1.2.6. I can confirm that the "Connect" button when trying to connect to a Hidden Wireless network so no longer greyed out & the problem has been resolved! As Sebastien mentioned in comment #24 up & coming updates have been passed through & have resolved the issue.

Because of this I'd say the status of this bug will need to be changed to Fix Released & close this bug.

Cheers.
