How to connect "polaroid tablet pmid921x" to my wireless?

[3WAYsplit]

Xmas added this: polaroid tablet pmid921x to my tech family.

I'm trying to connect this to my WAP. I was able to add my SSID to the available list,
but it won't stay connected. It keeps stating no internet connection.

My network setup is as follows:

Cable internet into Cable Modem
Cable Modem to Wired Linksys Router
Wired Linksys Router connects to: PC, Smart TV, Linksys WAP
Linksys WAP connects Wifi Laptop

I want to connect the "polaroid tablet pmid921x" to my Linksys WAP.

What do I need to do to get this to work with my setup?
