How to set up a Wi-Fi network

wi-fi connected devices
The Internet is a really powerful tool. It gives us access to all kinds of information at a moment's notice—think email, Google search, and Wikipedia. So there's something a little counter intuitive about only being able to use the Internet when you sit down at a desktop computer. What if you could use the Internet from anywhere in your home or office?
If you already have high-speed (broadband) Internet service at your house, it's pretty easy to create your own home wireless network. Commonly known as Wi-Fi, a wireless network allows you to connect laptops, smartphones, and other mobile devices to your home Internet service without an Ethernet cable.
So you wanna know how to set it up? then let's go!

Buy a wireless router

To create your own Wi-Fi network, you'll need a wireless router. This is the device that will broadcast the Wi-Fi signal from your Internet modem throughout your house. Your Internet service provider (ISP) may offer you a wireless router for a small monthly fee. If you've never set up a Wi-Fi network before, this may be the easiest option.
If you want to buy your own router, we'd recommend spending a little more time researching different options. PC Mag offers a comprehensive guide on How to Buy a Wireless Router.
Some Internet modems may already have a built-in wireless router, which means you won't need to purchase a separate one. 

Connect the cables

connecting the cables for a wi-fi router
  1. Once you've acquired a wireless router, you'll need to connect it to your existing Internet modem.
  2. Connect an Ethernet cable from your modem to the wireless router (there is usually a short Ethernet cable included with your wireless router for this purpose).
  3. Plug in the power cable for the wireless router.
  4. Wait at least 30-60 seconds and make sure the lights on your router are working correctly.

Configure your router

Next, you'll need to use your computer to configure your router's default settings. This includes setting a unique name and password for your wireless network.
  1. Using your web browser, enter the router's default IP address into the address bar, then press Enter. Your router's instructions should include this information, but some of the most common addresses include192.168.0.1, 192.168.1.1, and 192.168.2.1.
  2. The router's sign-in page will appear. Again, the exact sign-in details should be included with your router's instructions, but most routers use a standard user name and password combination, such as admin andpassword.
  3. Your router's settings page will appear. Locate and select the Network Name setting, then enter a unique network name.
  4. Locate and select the Network Password setting, and choose an Encryption option. There are several types of encryption you can use, but we recommend WPA2—this is generally considered to be the most secure.
  5. Enter your desired password. Make sure to use a strong password to help ensure no one else can access your network.
  6. Locate and select the Save button to save your settings.

Connect!

That's it! Now you're ready to connect to your Wi-Fi network and make sure it's working. The process for connecting to a Wi-Fi network will vary slightly depending on what type of computer or device you're using, but any system will require these basics steps:
  1. Locate your computer's network settings and search for nearby Wi-Fi networks.
  2. Select your network and enter your password.
  3. If the connection is successful, open your web browser and try navigating to a webpage like www.google.com. If the page loads, it means your Wi-Fi connection is working correctly!

Congratulations!

You see that its so simple,You've just set up your own home wireless network—way to go!

Linux Kernel Networking: Implementation and Theory

Linux Kernel Networking takes you on a guided in-depth tour of the current Linux networking implementation and the theory behind it. Linux kernel networking is a complex topic, so the book won't burden you with topics not directly related to networking. This book will also not overload you with cumbersome line-by-line code walkthroughs not directly related to what you're searching for; you'll find just what you need, with in-depth explanations in each chapter and a quick reference at the end of each chapter.

Linux Kernel Networking is the only up-to-date reference guide to understanding how networking is implemented, and it will be indispensable in years to come since so many devices now use Linux or operating systems based on Linux, like Android, and since Linux is so prevalent in the data center arena, including Linux-based virtualization technologies like Xen and KVM.

What you’ll learn

    •Kernel networking basics, including socket buffers
    •How key protocols like ARP, Neighbour Discovery and ICMP are implemented
    •In-depth looks at both IPv4 and IPv6
    •Everything you need to know about Linux routing
    •How netfilter and IPsec are implemented
    •Linux wireless networking
    •Additional topics like Network Namespaces, NFC, IEEE 802.15.4, Bluetooth, InfiniBand and more

      Who this book is for

      Software developers and architects, project managers, CTOs, network admins and architects, network security professionals, computer science researchers, and Linux kernel hackers. A basic knowledge of C and networking is required; basic knowledge of the Linux kernel is helpful but not mandatory.
