How to deal with Marvell LAN Port Is Not Working?

firmware for the router.

 

Defective Port

 

·         If your Marvell LAN port fails to work after installing the firmware and turning off or rebooting the router, the LAN port itself may be bad. This typically occurs when the router is dropped or otherwise damaged. The port may also be defective due to a manufacturing error. You can usually resolve this issue by contacting Marvell to have your router's LAN port repaired or replaced.

 

Bad Cable

 

·         When connecting a device to your Marvell's LAN port, you must use an Ethernet cable. If the cable is damaged in any way, the LAN port appears as if it's not working. Signs of cable damage include exposed or bent parts of the wire, although some cables may appear to be fine even though they aren't fully functional. If your cable is to blame for your LAN port issue, you can fix the problem by repairing or replacing it. Cables can be purchased at any electronics store or online.

Windows Firewall Connection Problems

tcx2018 -
Microsoft's Windows operating system includes integrated firewall software that can stop hackers and malicious software from accessing your computer when you go online. Sometimes the firewall prevents legitimate applications from connecting to the Internet. If some programs experience firewall connection problems, troubleshoot the issue by tweaking the firewall's settings.

About the Windows Firewall

 

·         The firewall feature in Microsoft Windows acts as barrier between your computer and the Internet, allowing only trusted programs on your computer to go online and communicate with the Internet. The firewall also blocks unrecognized, external online services from connecting to the data on your computer, thwarting attempts by hackers to hijack your computer or access your personal data.

 

Firewall Permissions

 

·         The firewall automatically authorizes many of the standard applications on your computer to access the Internet. For other programs and third-party applications that you download and install, the firewall prompts you to authorize the application when you first try to use it. The firewall connection problem occurs when a legitimate program or application that you haven't authorized tries to access the Internet from your computer. Because the program isn't approved, the firewall automatically blocks the connection.

 

Troubleshooting: Access Firewall Settings

 

·         Windows lets you configure the firewall to approve access for applications experiencing connection problems. To let a program through the firewall, select the "Control Panel" feature from the computer's Start menu. Type "firewall" into the system search field at the bottom of the Start menu. Click "Windows Firewall" in the Control Panel section of the search results.

 

Troubleshooting: Configure Firewall Settings

 

·         Accessing the Windows Firewall opens the firewall settings dialog in a new window. In the left-hand pane, click the "Allow a Program or Feature Through Windows Firewall" option. Click the "Change Settings" button with security shield logo. Before making changes, you may need to enter your Windows login password into the applicable input box. Windows Firewall displays a list of applications and programs in the main pane where you can select the program or application that you want to allow through the firewall. Save the changes and when you launch the program again, it should be able to go online normally.

Hardware vs Software

tcx2018 -
Hardware is any part of your computer that has a physical structure, such as the keyboard or mouse. It also includes all of the computer's internal parts.
Software is any set of instructions that tells the hardware what to do and how to do it. Examples of software include web browsers, games, and word processors. 
Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser (software) and using your mouse (hardware) to click from page to page. As you learn about different types of computers, ask yourself about the differences in their hardware. As you progress through this tutorial, you'll see that different types of computers also often use different types of software.
