Network Troubleshooting Case Study
The following are four troubleshooting scenarios that represent typical networking problems. Read each one carefully. For each question or activity that follows, write a 150-word response. Place your responses into a Microsoft® Word document, including the title of each scenario.
Part 1: Troubleshooting a Connection Problem
Chris works for a large corporation that has several branch offices in the city. Operating as a certified computer support technician, he must roam among the branch offices, solving computer and network problems as they arise. Chris receives a call that a remote office is having network problems. When he arrives at the remote office, he is told that the network is down. This office consists of seven computers connected to a router, which is connected to a cable modem.
Answer the following question: What are the first three things Chris should check?
The three things I think Chris should check is the computers, wireless router, and modem. Since there are 7 computers that are all connected to a router and modem and no network connectivity to either on sounds like or maybe an issue with the router or modem. Making sure that all cables are securely in place and ac power cords are plugged in, if not connectivity try rebooting the router and modem. Unplug the router first, and then unplug the modem. Count down to 10, then plug the modem back in and then the router. Give them both times to boot up and connect by watching the activity lights. Then try connecting to the internet again on your computer. At this point all the lights should be on and he will have connectivity to the computers. If this does not resolve the issue I recommend Chris to connect one of the computers directly to modem to eliminate the router. Reboot the modem again and try to get online, if it doesn’t connect then it is within the router. He must then troubleshoot the router. With the router’s user
