Hi @shawdon2,
Greetings from the Roku Community!
We appreciate you directly raising this inquiry with us. If you're currently using a Roku Ultra 4640, you might consider upgrading to a newer model. Newer Roku Ultras offer significant improvements like faster processing speeds, Wi-Fi 6 support, a better remote with USB-C charging, and potentially better overall performance, especially if you are experiencing lagging or slow streaming on your current device.
Hope you'll find this info useful.
Best regards,
John
