I am confused

Does this come with a built in wifi of some sort or do i have to buy a wireless bridge or something because my tv is in the next room not by my computer?

nevermind sorry guys i found my answer i just need a wireless USB adapter:) 

or a cable hardwired to your router.  that’s what i used.  60’ cable on ebay $6 with free shipping and no drop outs or stuttering to worry about.
