No wireless tv

Not sure what you mean by "wireless TV"?

If you want to share your DirecTV Stream service on that "wireless TV" you'll need a separate streaming device, like Roku or FireStick. That will need to connect to your home network via WiFi. 

The OP may also be referring to DIRECTV satellite because they say ‘needs a plug in’. OP do you mean DIRECTV satellite as in a coaxial cable or DIRECTV STREAM (Ethernet)?

yes. They will need  ethernet to use on their TV while I have a wireless router connection in the living room. It's for the back room. IT seems wireless connections doesn't work that good in my spare bedroom. 

Ethernet would be the preferred way to go then. Get a DIRECTV STREAM Osprey Box (if you haven’t already) and get it hardwired via Ethernet. Then, it should be good to go.

thanks for the information. i'll try my best to make that happen.
