How to connect a router to a receiver

My DirecTV setup just arrived today! I totally get how everything connects, but I’m stuck on one specific thing. My router is tucked away in one part of the house, the TV is in the living room on the other side, and my phone jack is way off in a third area. To get the router and the receiver together, I’d have to move the router right next to the TV, but since the phone jack is so far away, I’d end up having to drill out a whole new connection near the TV.

So, is there any kind of device that can wirelessly link the router to my DirecTV receiver?

Alternatively, could I connect the DirecTV box to a receiver that's actually close to the router (like in my brother's room) and then somehow mirror that picture onto a second TV? Someone mentioned this might be doable, though they said both TVs would just show the same channels. I wouldn't mind that at all, but how could I pull it off without buying an extra receiver?

So, you’ve got those TP-Link Powerline adapters sitting there, but let’s be honest—they aren't exactly cheap, are they? They essentially hijack your existing electrical wiring to ferry data signals through the walls. The setup is fairly straightforward: you plug one unit directly into a wall outlet near your router, and then you stick the second one right into a wall socket by your DirecTV set-top box. From there, you just bridge the gap using Ethernet cables—one from the router to the first adapter, and another from the second adapter to the box, and voilà! You're done. One crucial caveat, though: you absolutely must plug the adapter directly into the wall outlet. If you try to use a power strip or an extension cord, don't come crying to me when it fails to work.

Yeah, I did a little digging and realized that $133 is such a heavy investment that I’d honestly rather just run some cables myself than go that route. Does anyone know if there's a way to set everything up downstairs so I can watch on two different TVs at once—without needing to buy an extra receiver—as long as they're both showing the exact same thing? It might be a bit impractical, but for starters, anything is better than nothing.

Should you go with an HDMI or a SCART cable? Honestly, I’m starting to doubt you’ll even be able to track down one long enough to reach.
