I'm not sure I understand the question, but it is not necessary to connect a TV to Wi-Fi to use a Roku. The Roku connects to Wi-Fi (or, optionally, Ethernet on some models) and the Roku connects to the TV via HDMI.
We’re upgrading Roku Community to bring you a faster, more mobile-friendly experience. You may notice limited functionality or read-only access during this time. Read more here.
Planned Downtime:
Community will be unavailable for up to 24–48 hours during the upgrade window during the week of May 19th and you may notice reduced functionality.
In the meantime, for additional assistance, visit our Support Site.
We're sorry for this disruption — we’re excited to share what’s next!
