On the accessible device screen, it says "0 devices found.". I know the IP addresses. I can go online and there is no problem with monitoring. But when it comes scanning, there is a problem found and there is no description. Also, my ethernet card is Atheros AR8151 PCI-E Gigabit Ethernet Controller. By the way, there is no problem with my wireless card that produced by the same factory, Atheros AR9002WB-1NG Wireless Network Adapter. Could someone give some advice, please?

searching for accessible nodes is a MAC-Adress-Broadcast. Some antivirus-programms are blocking it with a function called like "Network-Protect" or similar. Try to disable this function or the whole anti-virus-scan. Maybe an other device in your network is blocking that function(switch, router). This MAC-address-broadcast is not routable with IP-routing, because there is no IP(lower-OSI-level)

In the project tree there is a section named "Online access". If you expand that, you can see all options on your TIA Portal installation for searching for devices. Expand the network adapter connected to your PLC. Have it update and perform a search.

The point is, wireless network adapter works fine but ethernet controller does not. Might it be due to driver installation of tia portal? Because I can connect with any other device over ethernet but it does not show up anything when it comes to accessible nodes/devices at Tia Portal.

-You can try to reinitial your interfaces. this FAQ may help you:

How do you generally parameterize the PG/PC interface and how do you ensure that the device driver can be selected and is visible?

Outdated or buggy network drivers can cause various issues, such as crashes, freezes, or blue screen errors. By keeping your drivers up to date, you can minimize the risk of these problems and enjoy a more stable computing experience.

As new network technologies emerge and operating systems evolve, it's essential to keep your drivers updated to ensure seamless compatibility. This allows your computer to communicate effectively with the latest hardware and software.

Updating your network and Ethernet drivers can lead to significantly faster data transfer speeds, reduced latency, and more stable connections. This is especially important for online gaming, video streaming, and other bandwidth-intensive activities.

If you encounter network-related issues, one of the first troubleshooting steps is often to update your drivers. Newer driver versions may include fixes for specific problems or offer better compatibility with your network environment.

If your computer has built-in Wi-Fi, updating your network drivers can often bring support for the latest wireless standards, such as Wi-Fi 6 (802.11ax). This can result in faster speeds, better range, and improved reliability when connected to compatible routers.

Newer driver versions may introduce additional features and settings that can enhance your network experience. These can include advanced power management options, improved diagnostic tools, or support for cutting-edge technologies.

Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.

In the Device Manager window, locate the device for which you want to install or update the driver. You can find devices under their respective categories, such as Display adapters, Sound, Video and Game Controllers, or Network adapters.

Click on the Browse button and navigate to the location where you saved the downloaded driver files. Select the appropriate driver file and click OK. Then, click Next to begin the installation process.

Many device drivers are not updated through the Microsoft Windows Update service. If you are having trouble finding the right driver, stop searching and fix driver problems faster with the Automatic Driver Update Utility. Automatic updates could save you hours of time.

The Driver Update Utility automatically finds, downloads and installs the right driver for your hardware and operating system. It will Update all of your drivers in just a few clicks, and even backup your drivers before making any changes.

After finishing its analysis, the driver scanning tool will present a summary of outdated or missing drivers on your system. You'll then have the option to either update each driver separately or perform a bulk update of all required drivers simultaneously:

If you have had recent crashes, power outages, viruses or other computer problems, it is likely that your drivers may have become damaged. Browse the list above to find the driver that matches your device hardware. To see more matches, use our custom driver search engine to find the exact driver.
