Problems hooking up DIRECTV to an LG

I received a DIRECTV Gemini BOX in the mail because I live in a multifamily development . I live in a Single Family Home and the HOA made an arrangement to allow Frontier Internet $$ and Directv as a package . My problem is that LG tvs have all the outlets to hook up other devices in the rear and the electrician choose a flat TV mount so the TV is flash to the wall and not possible outlets to connect the DIRECTV to it. I have been reading other people having almost  similar issues . My question is how to connect DIRECTV using WIFI instead of wires.
