ok long story short my father moving in with us has a android tablet and needs a wifi connection to use it. I currently have a modem/router to a network switch wired through the house on ethernet wiring and don't want to change that out. so I read somewhere briefly that that can disable NAT i guess in the router and turn it into a switch? wasn't sure how to go about doing that without screwing my whole network up, I'm somewhat an amateur about networking. so just wanted to know if i can hook up a wireless router to an existing network and how to disable the NAT. or maybe is there a adapter to add to my existing network from ethernet. thanks in advance.

What you want is to convert a wireless router into an access point. An access point is an extension of your exsisting network that lets your primary router do all of the address/routing/logic, it just provies wifi and more ethernet ports.

You can use any wifi router for this.
Set IP address of 2nd router. IP needs to be in same subnet of primary router but outside of DHCP server rage. Thus if primary router IP is 192.168.1.1 and DHCP server is .100-.254 then set 2nd router IP to 192.168.1.2 becuase the first three numbers match the router, and .2 is NOT in the DHCP server range.
Set subnet to 255.255.255.0 and gateway and dns to router IP.
Dissable DHCP server on 2nd router.
Plug ethernet port from LAN port of 1st router (or a switch)...

ADDED: You are not incorrect about the NAT, NAT provides a security layer blocking the WAN adapter from accessing your local devices without the local devices requesting something (this is why you have to port forward to allow an unrequested connection to a PC). An access ponit uses the LAN port and not the WAN port and thus bypasses the NAT firewall.
