  1. Module 5 Implementing Wireless Network Connections

  2. Module Overview • Overview of Wireless Networks Implementing a Wireless Network

  3. Lesson 1: Overview of Wireless Networks • What Is a Wireless Network? Wireless Network Technologies What Is Wireless Broadband? Security Protocols for a Wireless Network

  4. What Is a Wireless Network? A wireless network consists of: Can operate in two modes: Advantages Interconnected devices connected by radio waves instead of wires or cables • Extends or replaces wired infrastructure (wire-free) • Increases productivity for mobile employees • Provides access to internet in public places Disadvantages Ad hoc • Possible interference • Potential security risk • Additional management Infrastructure

  5. Wireless Network Technologies Windows 8 provides built-in support for all standards, but it also depends on: • The wireless network adapter • The wireless network adapter driver

  6. What Is Wireless Broadband? Wireless broadband: • Provides high-speed wireless Internet and data network access • Is comparable to wired broadband, such as ADSL or cable modem • Is used to provide constant connectivity to the Internet and corporate networks Windows 8 support for Wireless broadband: • Driver-based model for mobile broadband devices • Uses the same user interface regardless of the provider

  7. Security Protocols for a Wireless Network

  8. Lesson 2: Implementing a Wireless Network • Configuring Hardware for Connecting to a Wireless Network Wireless Network Settings Connecting to a Wireless Network Improving Wireless Signal Strength Process for Troubleshooting Wireless Network Connection Issues

  9. Configuring Hardware for Connecting to a Wireless Network • Connect and configure a WAP • Configure a wireless network adapter in the client computer Configuring Client Computers • Connect to a Network dialog box • Command line: netsh wlan • Group Policy

  10. Wireless Network Settings

  11. Connecting to a Wireless Network

  12. Improving Wireless Signal Strength To improve the signal strength: • Ensure close proximity to the WAP • Consider installing an external antenna • Check for physical obstructions • Add WAPs • Check for devices that may cause interference • Consider changing the wireless channel

  13. Process for Troubleshooting Wireless Network Connection Issues • Attempt to connect to a wireless network • Diagnose the connection by using Windows Network Diagnostics tool • Review the diagnostic information • Identify the problem from the list of problems found • Resolve the problem that you identified

  14. Lab: Planning the Implementation of Wireless Network Connections • Exercise 1: Planning a Wireless Network Exercise 2: Determining the Cause of Wireless Network Problems Logon Information No virtual machines are required for this exercise Estimated Time: 30 minutes

  15. Lab Scenario A. Datum Corporation is planning to implement a wireless network to enable certain employees to connect their laptops to the corporate network.

  16. Lab Review • In the lab, you were tasked with making the wireless network as secure as possible. Is this appropriate in situations where you want to make the wireless network accessible to anyone, for example, in a coffee shop? How will you go about configuring the wireless infrastructure to support access in this way? Is it advisable to connect this less-restricted wireless network to your corporate network? Can you think of a way in which legitimate users from your organization can connect wirelessly to your infrastructure from the same coffee shop area, while not providing the same access to anonymous users?

  17. Module Review and Takeaways • Real-world Issues and Scenarios Tools Common Issues and Troubleshooting Tips
