How to Bridge an Internet Connection

In the current age of computers and the internet, wireless has taken a huge leap in usage because of how much it has improved over the years. That’s good for many portable devices such as laptops, smart phones, etc. But for people using desktops a wireless adapter may not be included or you may want to have a stable connection. Shown in this article will be simple steps so that anyone can create their own bridged connection.

Steps

  1. Make sure the machines and Crossover Cable are working. To see if the cable is working plug it into both machines, if the port lights up than you know that it works, if it does not light up the cord is not in working order.
  2. Getting Started. On both machines go the the start menu, open the control panel and go to “Network and Internet”. The Local Area Connection should show up with no internet access in the window.
  3. Creating the Bridge on the host machine. Go to “Change adapter settings” on the left pane on the host machine. Two or more connections should show up. Highlight both Local Area Connection and Wireless Network Connection. Right click one of the icons you highlighted and an options menu should come up with only “Bridge Connection”, click it and it should take a second to set up the connection.
  4. Bridge already working? Some machines cards will automatically assign the needed network information for you, if it does an Icon on the client machines task bar will show up with a Monitor and a Fork like plug beside it. If the icon has a caution sign it means that the information needs to be assigned manually
  5. Error Checking. A new icon should show up in the window called “Network Bridge” and it should display the name of the wireless network you are connected to below “Network Bridge”, if not repeat step 3 to remove the bridge and restart the process.
  6. Accessing Command Line. Still on the host machine open the start menu and in the search bar type “CMD”, open notepad and be prepared to write down your network information.
  7. Getting the machines network information. In the CMD window type “ipconfig /all”, a large list of information should show up, scroll to the top and look for “Ethernet adapter Network Bridge:”, copy the IPv4 Address, Subnet Mask, Default Gateway, and the DNS Servers.
  8. Client Machine Setup. Now on the Client machine click on “Local Area Connection” a window should pop up called “Local Area Connection Status”, select Properties, and in that window double click “Internet Protocol Version 4 (TCP/IPv4)”.
  9. Entering IP information. To enter the network information select “Use the following IP Address”, now the three bars should be lit up. In the IP address row enter the IPv4 address from the host machine, and for the last section of numbers increase it by 1. Example: 192.168.1.179 becomes 192.168.1.180. The Subnet Mask is the same as what was copied as with the Default Gateway.
  10. DNS Servers. The DNS servers will also be changed to what was copied down from the host machines network info. For the first row enter the information as it was from the Host, and in the second row put in the same number but increase the last number by 1. Example 192.168.1.1 and 192.168.1.2.
  11. Finalizing the connection. Click the box about Validating Settings upon exit and click ok. It will take a second to validate but the connection should start working a few seconds after clicking ok. You’re new connection should be working now.

Warnings

  • These steps should only be used in context with a Windows 7 machine, as they are not guaranteed to to work on previous versions, or machines running another OS such as iOS, or Linux.
  • The connection speed will not be as fast as it was previously since you are splitting the connection

Things You’ll Need

  • A laptop with 1 Ethernet port (RJ45 specifically), and an active wireless connection
  • A Desktop (or laptop) with a working Ethernet port
  • A cross over cable to connect the two machines. To check if your cable is a crossover cable check the connector and look at the pin colours, if the two sides have the colours in different positions, you have a crossover cable.
