I'm sorry, but I cannot determine if the Ethernet network cable was removed without further information or context. If you provide me with more details or specific information, I would be happy to help you with your question. **

To switch from Ethernet to Network 3, you will need to go to your computer's network settings. From there, you can select the option to connect to Network 3 instead of Ethernet. Make sure you have the necessary credentials and permissions to connect to Network 3. Once you have selected Network 3, your computer should automatically disconnect from Ethernet and connect to Network 3. **

Ethernet is a standard communication protocol used for connecting devices in a local area network (LAN) and is commonly used in office environments. Industrial Ethernet, on the other hand, is a specialized version of Ethernet designed for use in industrial applications such as manufacturing, automation, and control systems. Industrial Ethernet typically has additional features such as higher reliability, real-time communication capabilities, and support for harsh industrial environments, making it more suitable for industrial use compared to standard Ethernet. **

The choice between Ethernet and WLAN depends on your specific needs and circumstances. Ethernet provides a more stable and reliable connection, making it ideal for tasks that require high bandwidth and low latency, such as online gaming or video streaming. On the other hand, WLAN offers more flexibility and convenience, allowing you to connect to the internet from anywhere within the range of the wireless network. If you prioritize speed and stability, Ethernet may be the better option, but if mobility and convenience are more important to you, WLAN may be the way to go. **

Ethernet itself is not inherently slow. The speed of an Ethernet connection depends on the type of Ethernet technology being used, such as Fast Ethernet (100 Mbps), Gigabit Ethernet (1 Gbps), or 10 Gigabit Ethernet (10 Gbps). In comparison to other networking technologies, Ethernet is generally considered to be fast and reliable for local area network (LAN) connections. However, the speed of an Ethernet connection can be affected by factors such as network congestion, distance from the router, and the quality of the Ethernet cables being used. **

To best hide Ethernet cables in a network, you can use cable management solutions such as cable raceways, cable trays, or cable sleeves to conceal the cables along walls or ceilings. Additionally, you can run the cables behind furniture or along baseboards to keep them out of sight. Using wireless networking technology can also help reduce the need for visible Ethernet cables in the network. **

Ethernet may not work due to various reasons such as faulty cables or connectors, incorrect network configurations, issues with network adapters or drivers, or problems with the network switch or router. It could also be caused by interference from other electronic devices, network congestion, or a malfunctioning network interface card. Troubleshooting these potential issues can help identify and resolve the problem with Ethernet connectivity. **

The choice between Ethernet and Wi-Fi depends on your specific needs and preferences. Ethernet typically offers faster and more reliable connections, making it ideal for activities like online gaming or streaming. On the other hand, Wi-Fi provides more flexibility and convenience, allowing you to connect multiple devices without the need for cables. Ultimately, the best option for you will depend on factors such as your internet usage, the layout of your home or office, and your personal preferences. **
