OSNF Group Assignment Home Network & Fibre Broadband CSF/IT NYP Year1(2024/25) Sem 2, Singapore

Objectives

After completing this assignment, the team should be able to:

1. Understand the fibre broadband WAN technology provided by Internet Service Providers.
2. Draw a diagram to illustrate how devices are interconnected by wired and wireless connections in a typical home network.
3. Understand wireless AP configuration settings in the residential gateway.
4. Understand TCP/IP protocols (DHCP & IP) and the configuration settings in the residential gateway.
5. Troubleshoot problems encountered in wireless LAN and recommend solutions.

Introduction

This is a group assignment. Students are to work in groups of 3 to 4 students to discover their home network and access the network configuration settings on their residential gateway (or wireless router).

Background Reading and Preparation on Home Network and Fibre Broadband 

Residential homes in Singapore can access the Internet through fibre broadband connection. Most homes with fibre broadband also have a home network which enables several computers to access the Internet at the same time.  Computers, smartphones, network printers and Smart TV as well as network devices such as modem/ONT, wireless router and Wi-Fi Mesh system can be found in a home network.

All students should read up and research into Fibre Broadband Connection to Homes and Home Networking Guide found in the following link:

• Research on the fibre broadband connection in terms of the type of optical fibre, type of connector and the technique used to support simultaneous download and upload streams over a single strand of optical fibre.

(6 marks)

• Based on the selected Home Network, take relevant screenshots of the residential gateway (or wireless router) configuration settings and answer the questions.

(8 marks)

• With the floor plan of the selected Home Network, draw a network diagram showing where the network devices and network-enabled devices are located and how they are interconnected. The diagram should show the followings with clear labelling:

• types of network cables and connectors
• IP addresses assigned to devices (both static and dynamic addresses)
• others such as TV, telephone, Wi-Fi Mesh, structured cabling

(30 marks)

• Take relevant screenshot(s) of the wireless 5GHz Band configuration settings and answer the questions.

(6 marks)

• For one of the rooms, the wireless connection to a laptop in the room is unstable when the door is closed.
• What is the likely cause of this problem?
• Evaluate TWO suitable solutions to provide stable wireless connection for the laptop.
• Select the preferred solution with justifications in the context of the selected Home Network.
