Hi there,
Thanks for the note. You'll want to start here to troubleshoot wireless connection issues or buffering on your device: https://support.roku.com/article/213122277-tips-for-improving-the-wireless-connection-to-your-roku-s...
In particular, changing the wireless broadcast channel on your wireless router to decrease interference, by choosing another channel not in use by other networks around you, typically helps improve streaming performance. Your ISP or wireless router manufacturer can assist you further with this.
Thanks,
Tanner
