Connect devices to your WiFi network

If you’re in an environment with more than one wireless network, like an apartment or office building, you can set up your Mac to join a preferred network by following these steps.

1. Open the Apple menu, indicated by the Apple logo.
2. Select System Preferences and then click Network.
3. On the list on the left, select WiFi. Then, select Advanced.
4. Drag your preferred WiFi network to the top of the list to give it the highest priority. Your computer will try to join this network first when in range.

If you’ve previously joined a network that isn’t secure, remove it from the list by selecting it and clicking Remove.

If your Android device is not connecting automatically, here's how to change the settings.

1. Open Settings.
2. Tap on Network & Internet and choose WiFi.
3. Tap your desired WiFi network within range. Networks that require a password show a lock symbol next to the network name.
4. After you connect, the network will be saved on your device. When your device is in range and WiFi is turned on, it will automatically connect to that network.
   
   

If you turn your WiFi off, your device will no longer automatically connect until you turn your WiFi back on. However, Android devices also include the ability to automatically turn on WiFi when in range of a known network. If you want to keep your WiFi off, you can turn off this function:

1. Open Settings.
2. Tap on Network & Internet and choose WiFi.
3. Scroll down and tap WiFi Preferences.
4. Select Turn on WiFi automatically.
   

By default, your Windows computer will automatically connect to a WiFi network it’s previously been connected to. If your computer does not automatically connect, troubleshoot the problem by disconnecting from WiFi:

1. Click on the WiFi icon on the taskbar.
2. Choose your WiFi network name.
3. Select Disconnect to forget the WiFi network temporarily.
4. Once you’ve disconnected from WiFi, choose the same network and reconnect. You may need to reenter the WiFi password to reconnect.
   

These instructions will vary slightly by device. Generally, you can disconnect or remove a saved network by going back into the same WiFi Network list you accessed when you connected.

General steps:

1. Make sure WiFi is turned on so that you can access the device's list of active wireless networks. 
   
   
2. Select the network (SSID) you want to remove. 
   
   
3. Long hold or click to open options for that network, then select Disconnect. You can also Forget or Remove the network to prevent your device from auto-connecting next time.

You can remove all saved networks if your device is attempting to connect to the wrong network, or as a way to reset WiFi if you are unable to connect.

Try these suggestions if you are having trouble connecting:

• Look up the wireless network settings if you don't have the modem sticker.
  
• Use the WPS button to connect certain devices without entering a password.
• Is the WiFi light green on your modem? If not, you may need to enable wireless in the modem settings.
• Troubleshoot WiFi connection issues.

If you're having trouble with a specific device, you will need to get additional guidance from the device manufacturer about how to connect to WiFi or troubleshoot connection problems. Go to the support site for the device to access manuals and guides.
