How to Activate Your Android’s Wi-Fi Radio

By Dan Gookin

The mobile-data connection on your Android is nice, and it’s available pretty much all over, but it costs you money every month. A better option for an Internet connection is Wi-Fi, the same wireless networking standard that computers use.

To make the Wi-Fi connection work requires two steps. First, you must activate the device’s Wi-Fi radio. Second, connect to a specific wireless network.

Wi-Fi stands for wireless fidelity. It’s brought to you by the numbers 802.11 and various letter suffixes too many to mention.

Follow these steps to activate your Android’s Wi-Fi radio under stock Android version 8.0, or Oreo:

  1. Open the Settings app.
  2. Choose Network & Internet.
  3. Ensure that the Wi-Fi master control is set to the On position. To further access Wi-Fi settings, tap the Wi-Fi item.

On earlier versions of Android, choose Wi-Fi in Step 2.

For current Samsung devices, follow these steps:

  1. Open the Settings app.
  2. Choose Connections.
  3. Choose Wi-Fi. The Wi-Fi master control is on the Wi-Fi screen.

To deactivate the Wi-Fi radio, which also disconnects the device from the Wi-Fi network, set the master control to the Off position.

  • Use the Wi-Fi quick setting to instantly activate or deactivate the Wi-Fi connection.

  • Once the Wi-Fi is activated, the phone or tablet automatically connects to any memorized Wi-Fi networks.
  • It’s okay to keep the Wi-Fi radio on all the time. It is not a major drain on the battery.
  • Using Wi-Fi to connect to the Internet doesn’t incur data usage charges — unless you’re accessing a metered network.
