4.4 Guided Practice – Connecting to the Internet In this practice, you will be connecting the network you created in the 3.3 Guided Practice (Program an IoT network using Packet Tracer) to the Internet using a DSL modem, a cable modem, and a fiber connection to your home. 3.3 Guided Practice- Program an IoT network using Packet Tracer Task 1 – Connecting your network to a DSL modem DSL Internet service is connected to your home office using the standard telephone connection to your house. We will be connecting from your network to a simulated Internet using Packet Tracer. First, open the packet tracer file containing your 3.3 Guided Practice network . Then open the Internet_Cloud.pkt file from your exercise so that you have both open on your desktop at the same time. When you open the Internet_Cloud packet tracer, you will see the following: You should have 2 separate packet tracers open on your screen as shown below: 1

On your 3.3 Guided Practice Packet tracer file , highlight all the items on the desktop area. Note: To highlight items in Packet Tracer, press and hold down the left mouse button and drag the cursor diagonally across the items. The selected items will turn greyish. Press CTRL + C to copy the items. Go to the Internet.pkt file. Press CTRL + V to paste the items to its desktop area. After a few seconds, your devices should all connect back via wireless to your wireless router and IoT controller and all have green connections. Your desktop area should now have both of your systems in the same desktop area. 2

STOP! Click File and save this Packet Tracer file as StudID_4.4 Guided Practice (Ex. JOESMU1234_4.4 Guided Practice) Go into your WAN Emulation devices (looks like a cloud) and select the DSL modem. Drag and drop it onto your desktop just above the WRT300N Wi-Fi router. Connect the DSL modem Wi-Fi router (Internet Port) to the using a straight-through Ethernet (copper straight-through) cable. Make sure to connect to the Internet connector on the Wi-Fi router. 3

DSL Modem Connection Wi Fi Connection Now select the phone cable connector from the connections list and connect your DSL modem to one of the modems within the cloud-PT connection at your Internet Service Provider (ISP). It doesn’t matter which of the modems you connect to at the ISP as they are all programmed to work the same way. After your cables have synced up (green lights), go into your Wi-Fi router GUI using your PC. Connect using the web browser and connect to 192.168. x .1 ( X being your age. Ref: 3.3 Guided Practice ). You may need to troubleshoot your network if your PC isn’t connected to the Wi-Fi router correctly. After you have connected your PC to the Wi-Fi router GUI go to the tab labeled Status. Go down until you see the Internet IP address. Verify that your Internet address is in the 11.0.0.0 network (you should get an IP address of 11.0.0__ 255.255.255.0). If not, hit the refresh button or release and renew until you get a valid address. 4

Verify that 11.1.1.10 appears next to “DNS 1” of Wi-Fi router GUI. If the IP address is not present, perform the following: 1. Click on Setup. 2. In the Static DNS 1: section, type 11.1.1.10. 3. At the bottom of the screen, press Save Settings . With the DNS IP address now set, check all your devices to see if they are now pulling the DNS Server IP address. If not, cycle the device to Static and then back to DHCP. Go back to your PC, open the command prompt window and attempt to ping server.com. Be patient. It may take a few moments to respond. It is okay if your first response is a time-out as long as it keeps working after the first timeout. 5

Your system is now connected to the “Internet”. Go to your laptop, open the web browser and attempt to pull up the webpage at server.com . Take a screenshot of the webpage. Note in the upper left corner where it identifies which device you are using. Deliverables for Task 1 ● Screenshot the Internet webpage at http://server.com from your laptop. 6

Task 2 – Switching Internet connection to a cable modem You are now going to switch your DSL modem out for a cable modem. First, delete your DSL modem. The connections with the Wi Fi router and Internet cloud will automatically be deleted as well. Replace it with a cable modem from the same WAN Emulation devices (looks like a cloud) location. There is also a second device that needs to be added to your desktop from the hubs menu. It is called the Coaxial Splitter. Place the Coaxial Splitter above the cable modem. 7

Connect from your Wi-Fi router (Internet Port) to the cable modem (Port 1) using an Ethernet cable. Connect from your modem to the Splitter and then on to the Cloud-PT with Coaxial cables (Blue lightning bolt). 8 Internet Port Port 1 Port 0 Coaxial0 Coaxial1 Coaxial7 or Coaxial8

After you have connected your devices and they have a good green connection everything should be working. Check by pinging from your tablet to the server.com server. What is the difference between connecting using the DSL modem and the cable modem from the user’s point of view? Verify that everything is working on your network and pull up the “Internet” by going to your tablet and pulling up the webpage at server.com . Take a screenshot. Deliverables for Task 2 ● Answer the question about differences between cable and DSL modem connections from the user point of view. ● Screenshot of the Internet webpage from your tablet. 9

Task 3 – Changing to a fiber connection Lastly, we are going to switch our connection from a cable modem to a fiber connection. The fiber connection relies on a fiber repeater instead of a modem so you must first remove both your cable modem and coaxial splitter. The fiber repeater can either be inside your home or “at the curb”. In either case, you will simply run an Ethernet cable from your Wi-Fi router into the fiber repeater as shown below. Verify that everything is working correctly on your network. Using your smartphone, ping server.com to make sure everything is working correctly. 10 Ethernet1 Internet

What is the difference between connecting using the cable modem and the fiber repeater from the user’s point of view? Verify that everything is working on your network and pull up the “Internet” by going to your smartphone and pulling up the webpage at server.com . Take a screenshot. 11

Deliverables for Task 3 ● Answer the question about differences between cable modem and the fiber repeater from the user point of view. The DSL modem runs through a house and is easier to set up in my opinion, and the cable modem runs through cable lines. ● Screenshot of the Internet webpage from your smartphone. 12
