Lab – Remote Technician – Fix a Network Problem (Answers Version)

Answers Note: Red font color or gray highlights indicate text that appears in the Answers copy only.

Introduction

In this lab, you will gather data from the customer and then instruct the customer to fix a computer that does not connect to the network. Document the customer’s problem in the work order below.

Lab Setup

Answers Note: In this lab, the goal is to demonstrate the special skills needed to help a customer fix a computer remotely.

  • On the wireless router, set the “Maximum Number of Users” setting for DHCP to one less than the number of computers connected to the wireless router with Ethernet patch cables.

Example: If you connect 4 student computers to each wireless router with Ethernet patch cables, set the “Maximum Number of DHCP Users” to 3. This setting is found under Setup > Basic Setup on the wireless router.

  • Clear the DHCP table on the wireless router so that each computer or mobile device needs to renew the IP address assigned by DHCP.
  • Renew the IP addresses of all the computers connected to the wireless router except for the computer that will be broken. Validate that the IP addresses fall in the DHCP range of the wireless router.

Renew the IP address of the “broken” computer. It will receive a 169.254.x.x address because the DHCP server has no more addresses to assign.

Problem Description

Well, the problem does not always seem to be there. Typically, not all computers on the network are used all the time, so everything seems to be fine. On some busy days, every computer is being used, and there is always one computer that cannot connect. I cannot figure out what the problem is because it is not usually on the same computer. When a computer cannot make connectivity, I check to make sure all cables and connections are fine.

Note: After you have given the level-two tech the problem description, use the Additional Information to answer any followup questions the technician may ask.

Additional Information

  • Windows 10
  • The computer has no new hardware
  • The computer has not been moved recently
  • An extra computer was added to the network recently
  • The computer looks the same as it did yesterday
