Wireless Connection error

[Mark McLeod]

There are ways to hide the SSID, but you'd have to do it on purpose by changing a setting on the DLink.

I'd suggest:
1) Moving the switch to 5GHz and waiting for it to reboot to see if it shows up
2) Checking with other computers/phones to see if they can see it (for both 2.4GHz & 5GHz settings)
3) Taking just the DLink home to see if it can be seen away from the school environment (some can suppress unrecognized APs).
4) Resetting once again to the factory defaults, but not using the FRC tool on it right away. See if the default "dlink" shows up in your list of available networks.

If it still doesn't show then the DLink wireless may be broken.
