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.
Remote Control Not Responding
Your Roku 3 device is not responding to the remote.
Battery Needs to be Replaced
If your remote is not working, it is possible that the batteries of your remote are drained or are not functioning well. Replace the two AA batteries, if necessary, using this guide and the LED light on the front of the remote should flash if it is working properly. Once the remote is working again, the remote pairing dialog should appear on the screen.
It might be necessary to make sure that your remote is paired to the Roku device. Re-pair the remote to the device by pressing and holding the black pairing button within the battery compartment for 3 seconds until the LED light flashes and the remote pairing dialog appears on the screen.
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.
If your applications are crashing or freezing often, then there may be an issue with the application. Try closing out the application you are currently using and open another one. Check to see if the problem reoccurs. If that application also crashes, then try rebooting your device. This can be done by unplugging the device, waiting several seconds, and then plugging it back in.
Roku 3 Firmware Out of Date
Your Roku may not be up-to-date to be able to the new updates to your applications. To solve this, go to the home screen and enter the Settings. Under Settings, select System, then System Update, and Check now. If an update is available, apply the update and check the functionality of your applications.
The Roku 3 device will not update and an error message or code appears on the screen.
Firewall is Blocking the Connection with the Roku 3 Update Server
If your Roku 3 is not updating, you may need to disable firewall. To do this, log into your router settings. For Windows devices you do this by opening a browser and connecting to 192.168.1.1. That should be the default for almost all routers. Find the firewall section. Click that section and turn off the firewall.
TV Not Communicating with Roku 3 Update Server
The TV might not be properly connecting with the Roku Update Server. To fix this, you can connect to the secret screen and update from there. To get to the secret screen use your remote to press Home five times, Fast Forward three times, Rewind two times. Next, scroll to “Update Software” and click “OK.”
Power light not turning on
Might be accompanied by slight buzzing sound with power plugged in
Could be caused by power LED leads touching the RF antenna
Need to disassemble the Roku 3, and take out the motherboard following iFixit guide. Then make sure the black cover containing the white power LED is sitting upright, and that the back pin of the LED is not touching the antenna. You can remove the cover of the power LED and examine the pins. Try plugging in power after making sure the LED pins are clear.
