It is very sad when your internet provider's customer service rep does not know what the WiFi SSID is. Good thing I found the answer anyway. Thanks, google-sensei. How to Hide Your SkyCable Wifi's SSID: The SkyCable wifi modem I have is the black tower, Technicolor. I assume you are already connected and logged in to the admin panel... Important: Note down the SSID before doing this. Because when you hit "apply," it will immediately disconnect without any confirmation prompt. Go to the Wireless > Primary Network tab. On the Closed Network field, select Closed. Then, go down the page and hit Apply. Done. Like I said, after a few moments it will disconnect, and you have to manually add the network name (ssid) and password to connect again.
