My RCA tablet doesn't find any WiFi when I turn it on. My RCA tablet will find and connect to my home and school WiFi only after I restart the tablet. Sometimes I have to restart more than once. I think this issue might have something to do with the power, hibernation, or sleep settings; but I'm unsure because I couldn't find any setting that fixed the problem.
I kept getting an authentication error when trying to connect to my WiFi even though I was connected to it till a few days ago. My other devices were still connected too it. So, I knew it wasn't my router. Here's what helped me:
In the WiFi screen, I selected the menu icon.
Selected Advanced settings
Clicked on WPS push button
I pushed the WPS button on the front of my router and it instantly connected
