Fix Wi-Fi network connection problems

If you're having trouble connecting to Wi-Fi — for example, the Wi-Fi icon on your device's screen is orange, or has an exclamation point  — try the solutions below.

After each step, try connecting to the Wi-Fi network again by opening a webpage on your mobile browser.

Note: Android isn't the same on all devices. These instructions are for devices running Android 7.1 and up. Check which version of Android you have.

Step 1: Check your settings and restart

  1. Make sure Wi-Fi is on for your device. Then turn Wi-Fi off and on again to reconnect.
  2. Make sure Airplane mode is off for your device. Then turn Airplane mode on and off again to reconnect.
  3. Press your device's Power button for about 30 seconds, until your device restarts. Rebooting gives your device a fresh start. Sometimes, that's all you need to fix an issue.

Step 2: Check the source of the problem

  • Device problems
    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 specific to your device.
  • Network problems
    Check whether your device can connect to another Wi-Fi network, like at a friend's house or a public network. If your device can connect elsewhere, the problem is most likely specific to the network.
  • Internet problems
    If your device connects to the network but doesn't access the Internet, the problem is most likely specific to your Internet connection.

Step 3: Troubleshoot by problem type

Troubleshoot device problems

Check your network password

Check that your device is using the right network password.

  1. Open your device’s Settings app Settings.
  2. Tap Wi-Fi and then the network name.
  3. To see the password, tap Show password.
Delete and re-add the Wi-Fi network to your device

Delete a Wi-Fi network from your device

  1. Open your device’s Settings app Settings.
  2. Tap Wi-Fi.
  3. At the top, make sure the Wi-Fi switch is On.
  4. In the list, tap the name of a saved network.
    Tip: On Android 6.0 and below, to see Saved networks, tap More More.
  5. Tap Forget.

Add the Wi-Fi network again

  1. Open your device’s Settings app Settings.
  2. Tap Wi-Fi.
  3. At the end of the list, tap Add network.
    Tip: On Android 6.0 and below, to see Add network, tap More More.
  4. Enter the network name (SSID) and other security details, if needed.
  5. Tap Save.
  6. You may need to enter a password to connect.
See whether an app is causing the problem

The problem may be caused by an app that you downloaded. You can reboot your device in safe mode to determine whether a downloaded app is causing the problem.

  1. Turn on safe mode.
  2. Once you're in safe mode, try connecting to the Wi-Fi network again.
    1. Open your device's Settings app Settings and then Wi-Fi.
    2. Tap the network's name​.
  3. See whether the Wi-Fi connection works in safe mode.
    • If the Wi-Fi connection works in safe mode
      An installed app is most likely causing the issue.
      1. Restart your device to exit safe mode.
      2. Uninstall recently downloaded apps one by one. See whether the connection works.
      3. Once you remove the app that's causing the problem, you can reinstall the other apps that you removed.
    • If the Wi-Fi connection doesn't work in safe mode
      There's most likely a problem with the Wi-Fi network or Internet connection.

Troubleshoot network and Internet problems

Restart the Wi-Fi router and modem

If you have access to the router or modem, try turning it 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. The router and modem should turn on automatically.
  5. Wait a few minutes, until all the lights on the modem and router are working as intended.

If the lights on the router or modem aren't flashing as intended according to the manufacturer or manual, there may be an issue with the modem, router, or Internet connection.

Contact the network administrator or your Internet Service Provider to see if they can resolve this issue. For example, there might be a service outage, or they might need to reset your Internet connection.

To connect to a public network, sign in

Public networks, like at cafes or airports, often have a login or authentication page that you must complete to use that network. If you don't sign in or accept the terms on that page, the public Internet connection won't work.

If you see an authentication page on your device, sign in or accept the terms to get on that network.

If you don't see this page after you connect to the public network:

  • To check for a notification that asks you to sign in to the Wi-Fi network, swipe down from the top of your device's screen.
  • To see whether the authentication page will come up, open a new browser window and try to load a website.

If that doesn't work, try reestablishing your connection to the network:

  1. Open your device’s Settings app Settings.
  2. Tap Wi-Fi.
  3. Tap the name of the network. Then tap Forget.
  4. At the top of the screen, tap to switch Wi-Fi Off. Then tap again to switch it back On.
  5. On the list, tap the network name.
  6. You should get a notification to sign into the network. To bring up the authentication page on your device, tap the notification.
  7. To connect to the network, accept the terms.
Reset all network settings

To reset all your network settings:

  1. Open your device’s Settings app Settings.
  2. Under "Wireless & networks," tap More.
  3. Tap Network settings reset.
  4. At the bottom, tap Reset settings.

Troubleshoot creating a Wi-Fi hotspot

Make sure "Portable Wi-Fi hotspot" is on
  1. Open your device’s Settings app Settings.
  2. Under "Wireless & networks," tap More and then Tethering & portable hotspot.
  3. Tap Portable Wi-Fi hotspot to switch it on.
    • If it was already on, switch it off and then on again.
    • If your device has never before had a portable hotspot, first tap Set up Wi-Fi hotspot.

You can learn more about tethering with Wi-Fi hotspots, Bluetooth, or USB.

Contact your mobile carrier

Not all mobile service providers support mobile hotspots.

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

When you reconnect

When you reconnect, check for the latest system update. Updates may bring improvements that can help fix device issues.

You can also learn how to change your advanced Wi-Fi settings.

Still can't connect?

If you still can't connect, please contact your Internet Service Provider, router manufacturer, or network administrator.
