An IP address is a unique identifier for a device connected to a network. It is made up of four groups of numbers separated by periods and each number has to be within the 1 to 255 range, such as 192.168.1.15. Devices connected to a network use IP addresses to identify and communicate with each other.

There are two types of IP addresses that devices can have assigned to them:

  • Public - assigned to devices connected to the global network, the internet.
  • Private - assigned to devices connected to personal or organizational networks, which in turn can use a gateway device with a public IP address assigned to access the internet.

Devices on your home network, should be assigned private IP addresses that fall within one of the following ranges:

Start End
10.0.0.0 10.255.255.255
172.16.0.0 172.32.255.255
192.168.0.0 192.168.255.255

    • Signal strength (wireless only)

  7. If you're concerned with the quality of your Roku devices internet connection you may want to check the following details:
    • For a wireless connection:
      • Signal strength: A measure of the strength of the wireless signal from your router.
      • Internet download speed: A measure of the speed of your internet connection. The date of the connection check is also reported.
    • For a wired connection only the Internet download speed will appear.

  8. Excellent or Good results likely mean the connection is functioning without issue. However, a Fair or Poor connection can lead to playback issues or other unpredictable behavior.

Anyone who uses a device that connects to the internet may encounter a situation where their device becomes disconnected or experiences an issue related to that connection. Checking the status of your network connection is a common practice that can help:

  • Determine what Wi-Fi connection you are currently using.
  • Determine what your device's current connection status is.
  • Make sure that your device is connected to the correct Wi-Fi network.
  • Make sure all of your devices are connected to the same network in order to be able to communicate with one another.

In order for a mobile app to discover and control a networked device, the mobile device running the app needs to be connected to the same home network:

  • If the networked device is using a Wi-Fi (wireless) connection, the mobile device needs to be connected to the same Wi-Fi network.

  • If the networked device is using an Ethernet (wired) connection, the mobile device needs to be connected to the Wi-Fi network that is being broadcast by the same router or gateway.
