If you're trying to share your internet connection with multiple devices at your house, you may be wondering how to do it without complicated networking. Luckily, your Windows or Mac computer can easily share its internet connection with the rest of the network. You can even turn your computer into a wireless access point so you don't need a router to connect your wireless devices.

Sharing a Windows Computer's Connection

  1. Configure your devices on the network. When sharing internet through your network, it will require a slightly different layout than a standard network. The basic layout is as follows:
    • Connect the computer that is sharing the connection (the "host") to the broadband modem via Ethernet or 4G hotspot via USB. If you are connecting a modem to the host computer via Ethernet, it will need two Ethernet ports (one to connect to the modem, and the other to connect to the hub or router).
    • Connect the host computer to the WAN port of a wired hub or wireless router using an Ethernet cable.
    • Connect the other computers to the hub or router using Ethernet or a wireless signal. Note that the connecting computers don't need any special settings, and can be running any operating system.
    • If you're just connecting two computers, connect them directly via Ethernet.
  2. Open the Network Connections window on the host computer. You can quickly open this window by pressing the Windows key + R and typing {{kbd|ncpa.cpl

Turning a Windows Computer into a Wireless Hotspot

  1. Follow the steps in the first section to enable internet connection sharing on the host computer. This method will allow you to use an unused wireless adapter on your Windows host computer to broadcast a wireless network that any other device can connect to, just like a wireless router. First, you'll need to enable internet connection sharing on the host computer by following Steps 1-5 of the first section.
    • The host computer will need to have a wireless adapter that isn't being used in order to broadcast a signal for other computers and devices to connect to. If the host computer doesn't have a wireless card installed, you can use a USB wireless adapter.
    • Make sure you only enable internet connection sharing on the adapter that's connected to the internet. Don't enable internet sharing on the wireless adapter that you'll be using to create the wireless network.
  2. Right-click on the network icon in your System Tray and select "Open Network and Sharing Center". This will open a new window with your active network connections.
  3. Select "Set up a new connection or network". This link can be found towards the bottom of the Network and Sharing Center window.
  4. Select "Set up a wireless ad hoc (computer-to-computer) network". If you are using Windows 8, you will need to download a free program like Virtual Router (, which accomplishes the same thing.
  5. Enter the settings for your new wireless network. Give the network a name and select "WPA2-Personal" as the Security Type. Make sure that the Security Key cannot be easily guessed.
    • Make sure to check the "Save this network" box, or you'll need to reconfigure it every time you reboot the computer.
  6. Connect your other computers and devices to the new wireless network. With the wireless network created and internet connection sharing enabled, you should now be able to connect any of your other computers or mobile devices to the wireless network just like any other wireless network. Enter in the Security Key you created in the previous step to connect.

Sharing a Mac Computer's Connection

  1. Understand the ways you can share your connection. OS X's Sharing menu allows you to easily share your Mac's internet connection using any of your installed network adapters. The computer sharing the network is called the "host" computer. You will need at least two network adapters installed in the host to share your connection; one to connect to the internet, and one to connect to the rest of your network.
    • If you have an unused wireless adapter (for example, your host is connected to the modem via Ethernet), you can use it to create a wireless network that other devices can connect to in order to access the internet.
    • If you have two Ethernet adapters, you can connect one to the modem, and the other to a network switch or router. Your other computers and devices can then connect to this network.
  2. Connect the host computer directly to the internet source. For the best results, it's recommended that you connect the host computer directly to your broadband modem via Ethernet, or use a USB hotspot. If your Mac doesn't have an Ethernet port, you can use a USB or Thunderbolt adapter.
  3. Open the System Preferences menu on the host Mac computer. Click the Apple menu and select "System Preferences".
  4. Click the "Sharing" option. This will open the Sharing window.
  5. Check the "Internet Sharing" box in the left frame. This will enable sharing for the host computer's internet connection.
  6. Click the "Share your connection from" menu and select your internet source. If you're connected to your modem via Ethernet, select it from the menu. If you're connected to a USB hotspot, select it instead.
    • Click Start to confirm that you want to enable internet sharing. Note that turning internet connection sharing on will likely disrupt any existing network you have set up.
  7. Select the method that you want to broadcast your connection. The method you choose depends on the way you want other computers to connect.
    • If you want to turn your Mac into a wireless hotspot, check the "Wi-Fi" box.
    • If you want to connect your Mac to a network hub or wireless router, select "Ethernet".
  8. Connect the host mac to the network hub or router's WAN port (Ethernet). If you opted to share your host's internet connection with a hub or router which the other computers will connect to, use an Ethernet cable and connect your host to the hub's WAN port.
  9. Configure your wireless settings (Wi-Fi). If you decided to turn your Mac into a wireless access point, click the Wi-Fi Options... to set a name and security key for the network. Make sure to select "WPA2 Personal" as the "Security" type, and create a password that won't be easily guessed.
    • If you're in a crowded living area such as an apartment complex, change the "Channel" to something other than 6 or 11, as these are the two most common ones. Doing so will help reduce interference.
  10. Connect your other computers and devices to the router or hub. Your host Mac is now ready to share its internet connection, and you can connect the other computers and devices as if it was a typical network.
    • If connecting via Ethernet, connect each additional computer to the LAN ports on the router or hub. They should automatically get IP addressed and be able to connect to the internet.
    • If connecting wirelessly, connect to the router as if you were connecting to any wireless network.


  • Sharing your internet connection at work or in another secured location may cause problems with the network. Sharing at home will likely disable any networks you had previously configured.Thanks!Helpful0Not Helpful0
