Chromebook Network connection issues can be frustrating, but with a few techniques in your tool belt, you will be able to diagnose and troubleshoot them with ease. Here are some ideas for how to fix common network connection issues: * Check the physical ethernet connection if you are using a wired connection. Make sure the ethernet cable is plugged into your computer and the router. * Try restarting your device to see if the network connectivity issues reset and resolve. * Run a network troubleshooter, such as the Chrome Connectivity Diagnostics add-on. The troubleshooter should be able to point you in the direction of the problem. * Try to pinpoint the problem by doing a trace route (outlined in Part A of this Activity) to identify where the packets are not moving forward. This may help you find out whether the problem is with your local network or the website’s network. * Try to ping a website’s server (outlined in Part B of this Activity). If it fails, you will be told what the problem is, such as Request Timed Out. It may be that the website is down. * Try to reset the router by unplugging it, waiting for 10 seconds, and then plugging it back in. * Escalate the issue by contacting your ISP if nothing else works. Many network administrators use the command prompt rather than a graphical user interface (GUI) to control the network. It can provide a quick and powerful way to accomplish various network tasks. Part A In this part of the activity, you will be using a command prompt to trace the route that a packet takes across the internet to get to your computer. Note: You must have Developer Mode enabled in order to complete these steps. Consult your teacher for help in getting set up. 1. Open a crosh terminal by typing the shortcut Ctrl + Alt + T. 2. Type in the command tracepath, followed by the URL of the website you want to check. For example, tracepath www.google.com 3. Take a screenshot of the results and paste it in a word processing document. 4. Interpret the results that you see in a short paragraph. (How many hops did the packets take to reach the destination? Why are there three times listed for each hop? What other information is listed besides the times?) Part B Another useful utility in the command prompt is the ability to ping

Part B Another useful utility in the command prompt is the ability to ping a website, which refers to the process of checking whether the website is active and able to be reached by sending a packet to it. In this part of the activity, you will use the command prompt to ping a website. 1. Open a crosh terminal (see Part A for instructions). 2. Type in ping followed by the website you’d like to check (pick one that you know is active). For example, ping www.amazon.com. If your ping does not stop after a few seconds, you can press Ctrl + C to manually stop it. 3. You should receive several replies, along with a time for each. At the end, some statistics about the ping are displayed. Take a screenshot of the whole result and paste it into a word processing document. 4. Interpret the results in a paragraph. (What is the IP address of the website you chose? What would be displayed if you pinged a website that is down?)
