Windows 10: After I reset this windows tablet it won't connect to my internet connection!!!

So I found this windows tablet at a thrift store and when I got home I figured out it was a tablet and it had a micro USB port but it didn't work but eventually it worked and I saw that someone named Lisa owned the tablet and there was a password on it the password hint was you! But I couldn't login so the next day I figured out how to reset it without the password and I set it up and I noticed that my previous network connection didn't show up I was able to get it on the correct date and time but I wasn't able to find my network connection do you know how to fix it let me know in the reply ch

Limited Connection (can't connect wirelessly)

I'm stumped.

My desktop is on the internet just fine but all of a sudden none of my Wireless devices can connect to my router to obtain internet.

They all say Limited Connection.

My droid simply doesn't ever get an IP from my router.

I have reset the broadband, IP, I've cleared the device list. Powered on and off but I still get the same issue.

What The F is wrong here?

This is for 2 Laptops, 1 Desktop and a Droid. All trying to connect via wireless.
