Help will not save router info

[jag77]

Toshiba 7 inch tablet, model AT7-C, running Android 4.4.2

My wireless router is configured to not broadcast its presence. After powering up the tablet the specifics of the router are entered. When complete Save is selected and the tablet connects within seconds. Later the tablet is powered off and still later back on. Every time it is turned off all the specifics for this router must be entered again. The WiFi section shows other routers in the area, but not mine.
What can I do to get the Save function the really save the data entered?
Thank you for your time.

I would bet this is a software bug, but one you can work around by making your network visible. Worth a try at least. If it will then remember the network, just give your WiFi a name that will not give your name or location away and secure it with a decent password and encryption. Then, who cares if your network is visible?
