Part 1: Identify and Work with PC NICs Step 1: Use the Network and Sharing Center. c. In the Network Connections window, what did you see? Identify and explain In the Network Connections window, I can see three items which are Bluetooth Network Connection, Ethernet, and Wi-Fi. Bluetooth is a proprietary networking standard used for short-range wireless connectivity and is often used to connect peripherals to base devices. Ethernet is the traditional technology for connecting devices in a wired local area network (LAN) or wide area network (WAN). Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet.

Link-local IPv6 Address is fe80::a85b:3fbe:eca3:c7d0%9(Preferred). IPv4 Address is 192.168.1.10(Preferred). Subnet Mask is 255.255.255.0. Lease Obtained is Wednesday, 26 October 2022 10:39:13 AM. The lease Expires is Wednesday, 26 October 2022 2:39:15 PM. Default Gateway is fe80::66ee:b7ff:fefc:6729%9 192.168.1.1. DHCP Server is 192.168.1.1. DHCPv6 IAID is 87582867. DHCPv6 Client DUID is 00-01-00-01-26-CB-08-96-00-2B-67-EC-6D-84. DNS Servers is fe80::66ee:b7ff:fefc:6729%9192.168.1.1. NetBIOS over Tcpip is Enabled. i. In the Wireless Network Properties window, click the Security tab. Explain what you saw. In the Wireless Network Properties window, after clicking the security tab, I can see the security type is WPA2-Personal, the encryption type is AES, and the network security key. j. Close the Wireless Network Properties and the Wi-Fi Status windows. Select and rightclick the Wi-Fi option > Connect/Disconnect. Explain what did you see. After I clicked > Connect/Disconnect on the Wi-Fi option, I can see the disconnect button on the SSID that my computer connected to on the bottom right of my screen. k. To join one of the other wireless network SSIDs listed, click the SSID that you want to join, and then click Connect. Describe what will happen next. When I clicked connect on the SSID that I want to join, it asked me to enter the network security key to enable me to click the next button below it and there was a cancel button too. Step 3: Work with your wired NIC. Based on your experience Step 2, do answer: a. Describe what did you see when you are on the Network Connections window, select and right-click the Ethernet option to display the drop-down list. When I right-click the Ethernet option, disable, status, diagnose, bridge connections, create shortcut, delete, rename, and properties are displayed in the drop-down list. b. What is the results when you click the Status window? When I click the status window, general info about the Ethernet is displayed. Under the connection heading, IPv4 and IPv6 connectivity are internet. Media state is enabled. Duration is 00:00:51. Speed is 1.0 Gbps. Then, there’s a details button. Under the activity heading, the bytes of wired connection for sent is 354,393 while the bytes for received is 7,907,140. Then, there’re properties, disable and diagnose buttons on the bottom. c. What is the purpose of Details? the purpose of Details is to show the details of the network connection. d. At the command window prompt and type ipconfig /all. What is the difference between Ethernet adapter information and the information displayed on wireless NIC? Close a Windows Command Prompt. The difference between the Ethernet adapter information and the information displayed on the wireless NIC is for the description of Ethernet, it displayed Realtek PCIe GbE Family Controller while the description for the wireless NIC is Intel(R) Wi-Fi 6 AX201 160MHz Part 2: Identify and Use the System Tray Network Icons In Part 2, you will use the network icons in your system tray to determine and control the NICs on your PC. Step 1: Use the network icon. c. In the Network Connections window, right-click Wi-Fi. What happens if you click Disable? When I clicked disable on Wi-Fi, the Wi-Fi turned off and my computer cannot connect to any Wi-Fi connections. d. You can also disable the Ethernet network. Explain how.

In the Network and Sharing Center, explain how your PC could resolve the network issue for you? In the Network and Sharing Center, my computer could resolve the network issue for me by clicking the troubleshooting programs. It will diagnose and repair network problems or get troubleshooting info. Reflection Question Why would you activate more than one NIC on a PC? I would activate more than one NIC on a PC because it improves throughput across the servers and provides an additional failover measure. It also enables more control such as better traffic isolation.
