I am unable to connect to a hidden wireless network on my ThinkPad running Ubuntu 14.04.
The login credentials are definitely correct and work on both an old iPad-Tablet and an Android phone, however when entering the hidden SSID and password on my Ubuntu laptop, the Wifi-Icon will flash for a few seconds and then show an error message, stating that no network connection has been established, without a password-prompt or any other response.
I am currently re-installing my laptop and have had this problem on Xubuntu 16.04, Ubuntu 16.04 and now on Ubuntu 14.04 (because I read that 16.04 in particular appears to have bugs regarding hidden wireless networks).
I can connect to the guest-network established by the same Wifi-Router without any issues, just connecting to the private hidden network on my laptop does not work.
Is there anything that I can try to solve this?
