If your network card is showing a limited or no connectivity, the first step you should take is to check your network connections to ensure everything is plugged in correctly. This includes power for routers, modems, and any other networking hardware you may have. Make sure all cables are firmly inserted into both the outlet and the device connected to it.
If everything appears to be plugged in correctly, try rebooting your modem and router. If you have a separate modem and router, reboot them both. To do this, turn off both devices and wait 30 seconds. Then turn the modem on first, and then the router. Allow several minutes for them to connect properly.
If your network connection is still limited or not working at all, you can try to reset the TCP/IP settings on your computer. The TCP/IP (Transmission Control Protocol / Internet Protocol) is responsible for managing how data is sent and received across the internet. To reset the TCP/IP settings, follow these steps:
1. Open the Command Prompt by typing “cmd” in the search box of your Windows Start menu.
2. Copy and paste the following command into the Command Prompt window:
netsh int ip reset c:\resetlog.txt
3. Press enter.
This command will reset the TCP/IP settings to their default settings. Once the settings are reset, restart your computer and check to see if your network connection is back to normal.
If the above steps don’t work, it’s possible that the problem lies with the network adapter itself. To check if the adapter is the problem, you can use the Device Manager to see if your network adapter is enabled and functioning properly.
Follow these steps to access the Device Manager:
1. Press the Windows Key + R to open the Run dialog box.
2. Type “devmgmt.msc” into the Run dialog box and press Enter.
3. In the Device Manager window, expand the Network Adapters category.
4. Click on your network adapter and select the Properties option from the context menu.
5. In the Properties window, select the General tab. On the right side, you should be able to see information about the adapter’s connection status and IP address.
If the adapter’s connection status shows as Disabled or Disconnected, try clicking the Enable button to enable the adapter. If the connection status shows as Connected, try unplugging and plugging the adapter’s cable back in. If the adapter’s IP Address is showing 0.0.0.0, right-click on the adapter and select the Repair option.
If none of these solutions worked, one of the last troubleshooting steps you can try is to uninstall and reinstall the driver for your network adapter. To do this, follow these steps:
1. Open the Device Manager by pressing the Windows Key + R and typing “devmgmt.msc” into the Run dialog box.
2. In the Device Manager window, expand the Network Adapters category. Right-click on your network adapter and select the Uninstall Device option from the context menu.
3. Check the box next to “Delete the driver software for this device” and click Uninstall.
4. Once the driver has been uninstalled, restart your computer.
5. After the restart, Windows should detect the missing adapter and install the appropriate driver automatically.
If you’re still having issues with your network card after trying all of the above steps, then it’s possible that the card is malfunctioning and needs to be replaced. If this is the case, contact the manufacturer of your network card for further assistance.
