Hi @maria23,
Thanks for posting to the Roku Community!
We're happy to assist you with your problem with your Roku stick. How are you powering your device? Did you connect your Advanced Wireless Receiver (AWR)? Please be advised that your Roku stick should not be plugged into the TV's USB port but directly into a wall outlet. Also, the Roku stick should be plugged into the TV's HDMI; the AWR into the Roku stick; the USB extender into the Advanced Wireless Receiver; and the extender into the USB adapter and the wall. The Advanced Wireless Receiver (AWR) should be included in your device's box.
Warm regards,
Eunice
