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. **

Smartphones do not typically have built-in Ethernet LAN support as they primarily rely on wireless connectivity such as Wi-Fi or cellular data. However, some smartphones can support Ethernet LAN through the use of adapters or dongles that connect to the device's USB-C or Lightning port. These adapters allow users to connect their smartphone to a wired Ethernet network for faster and more stable internet connectivity. Some examples of smartphones that can support Ethernet LAN with the use of adapters include certain models of Samsung Galaxy smartphones, Google Pixel phones, and iPhones. **

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. **

Most smartphones do not have built-in Ethernet drivers as they are designed to primarily connect to the internet via Wi-Fi or cellular data. However, some Android smartphones, such as the Samsung Galaxy S20 and the Sony Xperia 1 II, have the capability to connect to Ethernet using a USB-C to Ethernet adapter. This allows for a more stable and faster internet connection in situations where Wi-Fi may be unreliable. Keep in mind that not all smartphones support this feature, so it's important to check the specifications of the specific model you are interested in. **

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. **

If the network is connected via Ethernet but there is no internet access, there could be several potential issues causing the problem. It could be a problem with the Ethernet cable, the network configuration, the router, or the internet service provider. Troubleshooting steps could include checking the Ethernet cable for damage, restarting the router, checking the network settings, and contacting the internet service provider for assistance. **

There could be several reasons why you have no network access over Ethernet after a restart. It could be due to a faulty Ethernet cable, a problem with the network adapter, or a misconfiguration of network settings. It's also possible that the network infrastructure, such as the router or switch, is experiencing issues. To troubleshoot the problem, you can try using a different Ethernet cable, checking the network adapter settings, and ensuring that the network infrastructure is functioning properly. If the issue persists, you may need to seek assistance from a network technician. **

Ethernet controllers are hardware devices that enable a computer to connect to a local area network (LAN) and communicate with other devices on the network. They manage the transmission and reception of data packets over the network. PCI devices, on the other hand, are hardware components that connect to a computer's peripheral component interconnect (PCI) bus. This bus allows the devices to communicate with the computer's CPU and other components. PCI devices can include Ethernet controllers, sound cards, graphics cards, and other expansion cards that add functionality to a computer. **
