What is the model number of the problem Roku device? (Settings..System..About [press OK])
Normally changing the wireless channel (try ch. 1, 6, or 11) from within the router and lowering the Bandwidth/Channel Width to 20mhz will help most 2.4ghz connection issues. If your device is dual band, try using the 2.4ghz connection rather than the 5ghz. (if applicable)
Another option is to try a wireless extender that you can place in the same room (or at least closer) to the problem device. 20 feet is not that far, but you could be experiencing some interference from neighboring networks or other devices in your home. Again, that is where using an alternate wireless channel may be helpful.
Using your Roku remote, go to the Home Screen of your Roku. Press Home 5 times, then Up, Down, Up, Down, Up. You should be presented a Wireless Screen that tells you your signal strength and noise detected as well as some other values. Feel free to post the values next to the colored bars as well as the first line that includes Channel and ends with SNR. (or post a screenshot). With this screen present you can also move the Roku device around a little bit and see if these values improve or change. Then go back to the router and move that around a little bit and see if the values change. I would also make the settings changes regarding wireless channel and see if values change.
Normally, as long as the Strength is around 20 and green, your Roku device is picking up a decent enough signal to stream. The other numbers on the screen will indicate if there is some interference being detected.
Feel free to post back with an update. Include your router model number as well as the Roku model number and the results from above including any changes to the settings you make (better, worse, etc).
