cant get connected to WiFi on my Samsung tablet

[Grace_4]

I have tried to connect to the network, but my tablet keeps saying 'not in range' Do I have to go to my server to get help? This tablet was bought last year and has been working just fine until a couple of nights ago when I just could not get on the Wi-Fi network.

Try rebooting wireless router and the tablet.
