anmpuls, Thank you for sharing your experience with Wi-Fi connectivity on your DU6900 TV. This may be caused by a network issue. You might want to go through these steps to check your network connection: 1) Minimize interference by not using or turning off wireless devices. Also, verify that there are no obstacles between the TV and the modem or access point. (Wi-Fi strength can be decreased by appliances, cordless phones, stone walls/fireplaces, etc.) 2) If the wireless connection fails, connect the TV to the access point via a LAN cable. If the TV can connect to the Internet normally via the wired connection, there might be a problem with the access point. In this case, try using a different access point. 3) Perform a network test to check if there is a network problem. Press the Home button on your remote. Navigate to Settings > Support > Device Care > Self Diagnosis> Smart Hub Connection Test 4) Try a cold reboot of your TV by pressing and holding the power button for 5+ seconds until the TV turns off and on again. 5) Please also be sure you have the latest firmware update. You may want to enable automatic updates for convenience. Select Settings > Support > Software Update, then select Auto Update. I hope these tips help resolve your concerns.

Larry, To help resolve the issue with the YouTube app, I recommend running a cold reboot on your TV. There are two ways to do this: 1) Using the Remote: For most people, the easiest way is to hold down the Power button on the Samsung TV remote until the TV turns off and then on again. This should take about 5 seconds. 2) Using the Plug: If you do not have the remote, unplug your TV from the wall outlet or surge protector, leave it unplugged for 30 seconds, and then plug it back in. Next, I recommend ensuring the Youtube app is up to date by going to “Apps” on your Smart TV and selecting “Settings” from the top right corner. Next, select the YouTube app and select "Update," if available. If the issue persists or if there is no Update available, we will try deleting and reinstalling the YouTube app. To do so, navigate to “Apps” on your Smart TV and select “Settings” from the top right corner. Next, select the app. Finally, select Delete, and select Delete again to confirm. Then we will reinstall the app by returning to “Apps” on your Smart TV and selecting “Settings” from the top right corner. Click on “Youtube” and then select “Reinstall.” Also, please ensure you are running the latest Firmware update. Go to Settings> Support> Software Update.
