This is easily done by buying the following items:
Connect your modem to the Internet source port, next connect one of the modem outputs to the internet input port of the router. The router will set up a Wi-Fi wireless network in your dwelling & the Roku streamer will connect to it. Next connect the Ruku output to one of the HDMI input ports of your TV.
If you have an old TV with no HDMI ports it will have a white-red-yellow RCA audio visual input port. Connect it, using the extra cable provided with the Roku Express Plus, to the similar RCA input port of the Roku streamer.
Next get on your computer or smart phone, down load the Roku application to create your Roku streaming account & initialize your Roku streamer(s) following easy instructions. The app seems to accept phone # only in the format xxx.xxx.xxxx & does not remind you of it, and presto! you are all set to stream from Netflix, Amazon, Hulu, Spectrum, PBS, and many more. You will need accounts with each of these. One more thing, you can wirelessly stream to as many rooms in your house has you have TVs or home theatres, as long as you purchase enough Roku streamers. They are quite inexpensive.
A wonderful example of the miraculously magic serendipities of these technologies. I recently discovered that Roku does an excellent job of mirroring or casting what is on your small screen (smart phone, laptop or tablet) to your big screen & audio complex.
This works for casting/mirroring videos from streamers that use the DIAL protocol. Presently (December 2018) only UTube & Netflix do.
Do the following steps:
In view of this I will, from time to time add below lists of links to exceptional UTube videos for you to enjoy on a home theater.
