I have a Samsung 6500 series curved smart 4k tv with 2 HDMI connections, samsung 4k Bluetooth dvd with 1 HDMI connector. I purchased a Klipsch RSB14 Sound bar. I have cable service, time Warner with a newer Arris router. I haven't the foggiest idea how to hook it up, I'm old. I tried but don't know how to connect to Bluetooth or Wi-Fi. I don't have a optic connection on tv, can I use HDMI cables? Please help. Thank you
