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

Environment

Samsung devices.

Summary

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.
