How can I tell if my device is connected to a network?

Samsung devices

If you are experiencing network issues, check both of the following:
  • Wi-Fi status — Some apps might provide file transfers over Wi-Fi only. For example, IT admins can set up a corporate email policy to download attachments only when a device is connected to Wi-Fi. Also, files downloaded during a Knox update may be sent over Wi-Fi only.
  • Cellular status — If applicable.

To check the Wi-Fi status

  1. On the home screen, tap Apps > Settings.
  2. Under Network Connections, tap Wi-Fi; then tap the connected Wi-Fi network.
  3. Check the Signal strength.

To check the cellular and power status

  1. On the home screen, tap Apps > Settings.
  2. Find and tap About Device > Status.
This displays the following information:
  • Battery level — If you need to send or receive a large file, ensure that there is enough power to avoid interrupting the file transfer.
  • Network — The carrier that is currently providing cellular service.
  • Signal strength — A value of:
    • 100-120 dBm — Indicates a location with weak cellular reception
    • 60-80 dBm — Indicates strong cellular reception
  • Mobile network type — Indicates the wireless technology currently used by the carrier, which implies the data speed: 2G (GSM), 2.5G (GPRS), 2.75G (EDGE), 3G (UMTS), 3.5G (HSDPA, HSPA+), 4G (LTE).
  • Mobile network state — This should be connected for cellular service.
