Chosen Solution
I share WiFi with upstairs neighbor. My phones and laptop are signed in, but the tablet won’t pick it up. I have proper password, but still won’t authenticate.
Pls try these steps: [] Ensure that there are no other file sharing apps running in the background i.e. ShareIt etc (they can interfere with the attempt to connect to a local wifi) - - next [] Get access to the router and press the WPS button (manual authentication button) something like this
then tap the same icon you’ll find in your tablet (wifi advanced setting ). [] if it works, great! if not, your neighbor maybe blocking your tablet from connecting. He (I mean he or she) checks his router settings and ensure tablets arent blocked or your tablet’s mac ID isnt blocked. I assume he knows how to do it.
