Facing TV Problems? Ask a TV Technician.
Welcome to JustAnswer.comSorry to hear that you're having trouble with this, I'll do my best to help - Is it first time setting up that Roku device?
Okay, while setting the wifi, do you get your wifi router name and able to select it?
Did you put correct wifi password ***** establish a connection with the router?
Okay, that means the Roku device isn't connected properly with the internet
Please reset it to default settings by pressing the Reset button on it to start over the setup process and reply back with the result
If it is a Roku stick then check the sides of it for a reset button
If it is a Box then find a reset pinhole on the rear side of the box near the power input jack
Nice, please go through the setup and complete the network setup again to see how it worked
Okay, are the other devices such as laptop, computer, cellphone connected to the same wifi working fine, right?
Okay, it seems that Roku Express device is faulty, have problem with the wifi circuitry which is causing the problem, I am really sorry about this and you are going to have to return the unit to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you
The Roku device is strictly for the TV and there is no way to connect it to a computer
You have it replaced which is new info, I would recommend rebooting your wifi modem/ router at this point and try again to run the network setup
