Settings R Wrong On My Tablet.

last night when I went to bed the keyboard was working fine. The internet made some updates to the tablet and that's what messed it up. Now the settings are all wrong for the keyboard on the tablet and I don't know how to get them back right. I think I messed them up worse !! Because they made me mad cause my keyboard won't work now, So I tried to change a bunch of stuff to get it back right and I don't know what all I done. It says the Bluetooth is on, but before when it was on it would light up white now it stays gray, but still says it's on. Idk ? Help plz !
