Hi Thomas, Thank you for sharing your thoughts on the available inputs for the U8000F. Your TV has 3 HDMI ports and is Bluetooth-enabled.

A J,<br /><br />Thank you for sharing your experience with Wi-Fi connectivity. If your TV is having trouble connecting to the network, the following steps may help resolve the issue:<br /><br />Signal &amp; Setup Tips:<br />1. Check TV-to-router distance – Your TV should be within 50 feet of the modem or access point for reliable signal strength.<br />2. Minimize interference – Turn off nearby wireless devices and make sure there are no physical barriers (stone walls, fireplaces, appliances) between the TV and router.<br /> Power Cycle Devices:<br />3. Restart both your TV and router – Unplug both devices for at least 30 seconds, then plug them back in and allow them to reboot fully.<br />Connection Type:<br />4. Evaluate your connection method –<br />o If using Wi-Fi, move your router closer to the TV and eliminate any obstructions.<br />o For a more stable connection, we strongly recommend using a wired Ethernet cable.<br />o If already using Ethernet, verify the cable is working by testing it with another device.<br />Run Built-In Diagnostic Tools:<br />5. Network Test: Settings &gt; Support &gt; Device Care &gt; Self Diagnosis &gt; Smart Hub Connection Test<br />6. Wi-Fi Check: Settings &gt; Support &gt; Device Care &gt; Self Diagnosis &gt; Wi-Fi<br />Last Resort:<br />7. Perform a Factory Reset (if issues persist): Settings &gt; All Settings &gt; General &amp; Privacy &gt; Reset &gt; Factory Data Reset. Note that this will return all settings to their original defaults.<br /><br />If these steps don’t resolve the issue, please reach out to Samsung Support at 1-800-SAMSUNG, available 8AM – 12AM EST, 7 days a week.
