Alternatively, you can check the Device Manager. Press the Windows key + X and select “Device Manager” from the menu. Expand the “Network adapters” section. If your network card is disabled, it will have a small down arrow icon on it. Additionally, if there’s an issue with the driver, you might see a yellow exclamation mark next to the network adapter’s name.

What do I do if enabling my network card doesn’t work?

If simply enabling the network card through the Network Connections window doesn’t work, the first step is to restart your computer. A simple reboot can often resolve temporary glitches and allow the adapter to function correctly. Next, try updating the network card driver. Right-click the network adapter in Device Manager, select “Update driver”, and choose “Search automatically for drivers”.

If updating the driver automatically doesn’t solve the problem, consider manually downloading the latest driver from the manufacturer’s website. Uninstall the current driver in Device Manager, then install the downloaded driver. As a last resort, try running the Windows Network Troubleshooter. You can find it in Settings > System > Troubleshoot > Other troubleshooters > Network Adapter. This troubleshooter can often automatically diagnose and fix common network problems.

How can I prevent my network card from being disabled automatically?

To prevent your network card from being disabled automatically, adjust the power management settings. Open Device Manager, expand “Network adapters”, right-click your network card, and select “Properties”. Go to the “Power Management” tab and uncheck the box that says “Allow the computer to turn off this device to save power”. This will ensure that Windows doesn’t automatically disable the network adapter when it deems it unnecessary.

Another way to prevent automatic disabling is by modifying your power plan settings. Go to Control Panel > Hardware and Sound > Power Options. Select your active power plan and click “Change plan settings”. Then, click “Change advanced power settings”. Find the “Wireless Adapter Settings” or “Network Adapters” section (depending on your adapter) and ensure that the “Power Saving Mode” is set to “Maximum Performance” or “No Power Saving”.

If the hardware connection seems fine, try scanning for hardware changes in Device Manager. Click “Action” in the menu bar and select “Scan for hardware changes”. This prompts Windows to redetect any connected hardware, including the network card. If this doesn’t work, try booting into Safe Mode with Networking. If the network card is recognized in Safe Mode, it suggests a conflict with another program or driver installed in normal mode.

How do I enable my network card using the command prompt?

You can enable your network card using the command prompt with administrative privileges. First, open the command prompt as an administrator by searching for “cmd” in the Start menu, right-clicking “Command Prompt”, and selecting “Run as administrator”. Then, type the command `netsh interface show interface` and press Enter. This command will list all network interfaces and their current status.

Identify the name of your disabled network card from the list. Then, type the command `netsh interface set interface name=”[Your Network Card Name]” admin=enable` and press Enter, replacing “[Your Network Card Name]” with the actual name of your network card. If the command is successful, it will enable the network card. You can verify this by checking the Network Connections window (ncpa.cpl) or Device Manager.

What should I do if the troubleshooter reports “A network cable is not properly plugged in or might be broken” when my connection is wireless?

This message, while usually related to Ethernet connections, can sometimes appear erroneously for wireless connections. First, ensure that Wi-Fi is enabled on your computer. Check the system tray for the Wi-Fi icon and make sure it’s turned on. Also, verify that Airplane Mode is disabled, as this will prevent any wireless connections.

If Wi-Fi is enabled and Airplane Mode is off, try restarting your wireless router or modem. Power it off, wait 30 seconds, and then power it back on. After the router restarts, try reconnecting to your Wi-Fi network. If the problem persists, consider updating your wireless adapter’s driver as described previously. The issue might be caused by outdated or corrupted drivers even if the message appears inaccurate.
