Hello! Thank you for reaching out! I see how this can be frustrating with your remote doesn't work properly. You can try the following below to help solve this issue,
1. Switch the TV off.
2. On the remote, hold down the "back (Return)" button and the "4 Colour" button together for about 15 seconds until the LED stops flashing. This process will reset the remote and unpair it from the TV.
3. Switch the TV on and the Bluetooth connection between the remote and TV should re-pair.
While your internet may be fine you could also reset the connection to see if that makes any difference.
If this does not help I would recommend getting a new remote. You can purchase a new one at samsungparts.com.
