Network - Wireless & Wired Connections

My roku keeps saying it can't connect to the internet. Everytime I try to use an app to stream something it defaults back to the start up screen and says the internet is not connected.

What model Roku do you have?

Roku models Express, Express+, Premiere, and Premiere+ cannot connect to the 5 GHz wifi band, only to the 2.4 GHz band. If you have one of these models and a dual band router with both 2.4 and 5 GHz bands, be sure the router's 2.4 GHz band is turned on. 

There have been numerous reports lately of people with ISP-provided routers having had their 2.4 GHz band disabled and having to have their ISP re-enable it.

If that's not the problem, try this:

• Restart your router (even if other devices have no problem finding and connecting). Sometimes that's all it takes, if not keep going.
• Restart the Roku to clear its memory via Settings > System > System restart (for a Roku TV it's Settings > System > Power > System restart). Again sometimes that's all it takes, if not keep going.
• Find and connect to your network via Settings> Network > Set up connection

If that doesn't fix it, try disconnecting the power to your Roku for a few seconds.  When it comes back up, see if you then can set up the network connection.
