The coax out is a digital sound output. You can not use that on your soundbar. The sub out is for hooking the tv to a subwoofer (bass only). You gonna have to use the Headphones output, buy a good 3.5mm to rca cable preferably one with a built-in noise filter so it can attenuate the "hum". Also try lower the volume on the TV so you can have less distortion. That's all!

Connect the base to the audio out jacks on your tv.

you cannot use the usb port on the tv to connect your router. If there is a wi fi setup menu on your tv then it will connect to a wireless router once set up correctly. If your router is not wifi capable then you'll need to get one.
