How do I activate fox now on my roku 3 - Roku XD Streaming Player 1080P Wireless-N (2050X)

https://support.roku.com/category/115001360548--troubleshooting

Fox has several different applications that allow streaming from the internet using Roku, Amazon Fire, and various other devices. Look for Fox under the applications section, select it, the application should begin downloading and then installed. If you have additional questions concerning Roku specifically, they have a nice website support section and have provided me very helpful customer service in the past.

Subscribers to participating cable and satellite providers can watch the latest episodes of over a dozen of FOX's TV series on the FOX NOW Roku channel. Currently (July 2013) participating are AT&T Uverse, dish, Mediacom, and Verizon FiOS. All Roku users can watch promo videos, behind-the-scenes interviews, and clips, and other select content. Make sure your Internet provider is on the list.

first of all, make sure all your connections are secure and threaded all the way in. Next, go to the main menu and press 5 (configuration) and press 1 (search for channels) if this doesn't work, press 4(signal strength meter) and see how strong your signal is. You may just need to re-position your antennae. If all else fails try system reset(number 5) and repeat search for channels. I've had similiar experiences with mine but I have a 62% signal strength and still get 20-something channels. Hope this helps.
