The hidden status of the Wi-Fi network I am being allowed to connect to is not my option. I am using that Wi-Fi network now, to post this question. every time I boot up Ubuntu 16.04 LTS it fails to connect there, pops up a message saying that Wi-Fi networks are available (there are 5 non-hidden ones that are not usable) and I must manually select "Connect to Hidden Wi-Fi Network ..." and manually type in the SSID, select the type of "Wi-Fi security", and enter the password. It works fine until I reboot. At times when I am at other locations, other networks which are not hidden work automatically just fine after I select it once. I want to have this network saved and automatically connected when I reboot. How can I get that?
