Fix Wi-Fi connection problems

If you're having Wi-Fi connection problems, like with Wi-Fi authentication or staying connected, try the solutions below. For example, try these steps if the Wi-Fi icon on your phone's screen has an exclamation point Wi-Fi problem.

To test whether each solution works, try to open a webpage on your phone.

Note: Some of these steps work only on Android 8.1 and up. Learn how to check your Android version.

Step 1: Check settings & restart

  1. Make sure Wi-Fi is on. Then turn it off and on again to reconnect. Learn how to connect to Wi-Fi networks
  2. Make sure Airplane mode is off. Then turn it on and off again to reconnect. Learn how to enable and disable Airplane mode.
  3. Press your phone's power button for a few seconds. Then, on your screen, tap Restart Restart. (If you don't see "Restart," hold the power button for about 30 seconds, until your phone restarts.)

Step 2: Find the problem type

  • Phone: Try connecting to the Wi-Fi network with another device, like a laptop computer or friend's phone. If other devices can use the network, the problem is most likely with your phone.
  • Network: Check whether your phone can connect to another Wi-Fi network, like at a friend's house or a public network. If your phone can connect elsewhere, the problem is most likely with the network.
  • Internet: If your phone connects to the Wi-Fi network but you still have no internet, the problem is most likely with your internet connection.

Step 3: Troubleshoot by problem type

Internet & network

Restart the router & modem

If the Wi-Fi router and modem are yours, try turning them off and then on again.

  1. Unplug the router and modem's power cords from the power outlet for 15 seconds.
  2. Plug the power cords back in.
  3. Check that all cords and cables are secure at both ends.
  4. Wait a few minutes, until the lights on the modem and router are working right. (See the device manual or manufacturer's support site.)

If the lights aren't working right, you could have an issue with the modem, router, or internet connection.

Contact the network administrator or your Internet Service Provider. For example, there could be a service outage, or they could need to reset your connection.

Sign in to a public network

Public networks, like at cafes or airports, often have a webpage for you to complete. If you don't complete that page, the public connection won't work.

Contact your mobile carrier

Not all mobile service providers work with mobile hotspots.

If you have issues, check with your carrier. Ask whether your phone can connect to mobile hotspots and whether they're in your data plan.

When you reconnect

When you reconnect, we recommend checking for the latest system update. Updates can bring improvements that help fix issues. Learn how to check and update your Android version.
