No Wifi Connection
Your Roku 3 is not connecting to WiFi.
Incorrect WiFi Login Information
Ensure that the login information to your network is correct.
WiFi Out of Range
If your Roku 3 player is not connecting to WiFi, it is possible that the WiFi signal from the router is out of range. In order to strengthen the signal, move the router and Roku 3 so that there are fewer objects and walls between them. You should also avoid putting the router in the basement, near a window, or near other electronics that may emit interference. Do not place the Roku 3 device or the router in enclosed areas that can block the signal. You could also re-orient the router’s antennas towards the device. For the most reliable connection, you may connect the Roku 3 directly to the router via an Ethernet cable.
System Needs to be Rebooted
It may be necessary to reboot both the router and the Roku 3 player. Unplug both devices and wait 5 seconds before plugging them back in. Retry wireless connection setup.
Wrong IP Address
If your device is unable to connect to your network, check your IP settings for your wireless connection. Under Settings, go to WiFi and select your network settings. If the method to obtain the IP address is set to “manual”, change this to “automatic”.
Low video Quality
Your Roku 3 is connected to High Speed Internet but is streaming poor video quality.
Weak Connection Between Roku 3 and Router
To strengthen the connection between your Roku 3 and router, move your Roku 3 to a higher area or away from any other devices that may be interfering with the connection. If this does not work, update your router firmware. To do this refer to the section entitled “Applications Crashing.”
Speed of Broadband Connection
To increase the speed of your broadband connection, discontinue the use of any other devices connected to the network being used by the Roku 3.

Both Remote and Roku Need to be Restarted
You may need to restart both the remote and Roku 3 device in order to pair the two devices. Unplug the power cord from the device and wait for 5 seconds until you reconnect the power. Once the Roku loading screen comes on, remove and reinsert the batteries in the remote. Next, you press and hold the black pairing button within the battery compartment for 3 seconds while the Roku continues to boot up. Once done, check to see if your remote is working.
Remote Needs to be Cleared
It is possible that the remote needs to be cleared and re-paired. You will want to remove the battery compartment cover and unplug your Roku player. Press and hold the A, B and black pairing button all at once until the LED light flashes. The LED should flash three more times to indicate that the remote is cleared. Reconnect the Roku player to power. Now, press and hold the purple pairing button until the LED light flashes again to indicate that the remote is paired.
Your application crashes or freezes randomly while using it.

This can be done by unplugging the device, waiting several seconds, and then plugging it back in.
