So my wifi router is in the oppset side of where my computer is. I gate horrible ping in games and even surfing at the Internet goes slow. I can cable inside my living room and outside it can get down to 20 minus degreds i dont know if the cable can handle that. And the power line i bougt didnt work because you need to be at the same powerline to make it work. So how can I get stabile conection to my computer?
