I'm aware of similar threads like this:
How do I connect a Windows 8 laptop to a wireless network (which has a hidden SSID)?
but apparently there are no definite answers to this question. In short, connecting to hidden networks fails in Windows 8.
I've attempted connection to the same hidden network through Win7, Ubuntu and Android and have succeeded through all of them.
I've tried creating a manual connection through Network & Sharing Center.
I don't have access to the router and can't modify the visibility of it, even though I'm aware that a hidden network is not the best security practice.
How can I fix this? If there are Windows logs I can post to help resolve this problem, please do let me know.
