Hi ANGELO, Thank you for purchasing the Samsung AU8000 and for sharing your detailed review. The feedback you have provided regarding the sound quality and connection issues you are experiencing are important to us and will be shared with our internal teams. We suggest you try the following to improve your experience: 1. Use 5Ghz Wi-Fi if possible 2. Try wired LAN if available 3. Try repositioning the router so there are no obstacles between your TV and the router Please also be sure you are running the latest firmware (v.1903.0). You can check to see what software version your TV is using and if there is an available update through the settings on your TV. Go to: Settings > Support > Software Update. You may want to enable automatic updates for conveniences. Go to Settings > Support > Software Update, then select Auto Update. Additionally, to optimize the smart TV performance, please try Device Care option under the Support Menu. Go to Settings > Support> Device Care > Start Device Care. This improves your apps performance as it frees up unused cached memory and closes background apps. To tune the sound to your liking, you may want to try adjusting the several sound settings to suit your personal sound preferences. You can change the Sound Mode by going to: Settings > Sound > Sound Mode You can also customize the sound with Expert Settings by going to: Settings > Sound > Expert Settings I hope these tips help you enjoy the experience provided by your new Samsung TV.
