So I just encountered the problem on a new Asus Vivitab Smart, and searching on Google this appears to be "a thing" with win8. Here is one such discussion with more info on the matter: Windows 8: Hidden wireless networks will not reconnect on - Microsoft Community Has anyone with this issue managed to permanently solve the problem without resorting to annoying steps on each restart or wakeup? Has anyone with this issue tried win 8.1 preview to see if it has been addressed? And finally, what is everyone's thoughts on hidden SSIDs anyway? Microsoft seems to think they're evil.
