To help troubleshoot a slow internet connection on your smart TV, here is a list of things to consider:

1. Check the nearby router to be sure that all cables are properly connected and that there are no errors.
2. Look for any nearby routers or mobile hotspots and make sure they aren't interfering with your signal.
3. Connect your TV to the network via an Ethernet cable if possible.
4. Check for any available updates that might improve your connection speed.
5. Confirm that no other devices are using up a significant amount of your internet bandwidth.
