Comparable to a smart TV lacking internet connectivity, a Roku device will truly operate even when it’s not linked to your Wi-Fi. That said, your options will be quite restricted when offline. None of your Roku’s streaming applications (such as Netflix, Hulu, Disney+, etc.) will actually work, and even the clock displayed in the upper-right corner of Roku OS will not appear. Nevertheless, some Roku users might still find options available.
If you own the Roku Ultra, Roku Streambar SE, or any previous Roku model that has a USB port, you can still utilize the Roku Media Player app to watch, view, or listen to content stored on a USB flash drive or other external storage devices.
The newest iteration of the Roku Ultra features a USB 3.0 port and accommodates a variety of video, audio, and image formats, including MKV, MP4, MOV, FLAC, AAC, JPG, and PNG. The Roku Streambar SE similarly supports file formats but incorporates a USB 2.0 connection.
