If the basic checks and fixes do not resolve the issue, you may try a few more-than-the-basic solutions, such as:

  • Ensuring the router is located in a proper place and is not overheating
  • Testing the port by using a different device or in a different location
  • Checking for interference from other nearby devices and removing them if needed
  • Using a different power source for the router to rule out the chances of power being the culprit
  • Scanning the system for existing bugs and malware
  • Disabling firewall or security software temporarily
  • Performing a factory reset
  • Verifying and resetting the network settings of the device if necessary
  • Checking and changing the IP address to rule out chances of conflicts
  • Going through the router logs and reviewing them carefully to find any error messages
  • Checking and replacing the damaged, failing, or malfunctioning hardware
  • Updating router drivers
  • Updating the router firmware and reconfiguring it
  • Contacting your ISP to know and resolve any service-related issues

Here are the steps to follow systematically for the advanced solutions to the Wi-Fi router port issue and restore the proper functionality of your network.

Method 1: Rollback or Update Drivers

If the basic checks and fixes did not work, chances are that the driver is faulty. There are a few things to do in this case.

First, roll back the driver to see whether the issue is due to incompatibility or a bug in the updated driver. If it is not, update the driver.

Finally, you must uninstall the driver and let Windows install a generic driver version for the network card.


To roll back the updated driver to the previous version:

  • Press and hold the Windows key and press R.
  • Type devmgmt.msc in the Run dialog box.
  • Hit Enter.


  • In the Device Manager window, double-click on Network adapters.
  • Find and double-click on your network device.
  • Go to the Driver tab.
  • Click on Roll Back Driver.
  • Follow the on-screen instructions.

Clicking on Roll Back Driver

Note: If the Roll Back Driver button is greyed out, as it is in this case, you cannot go back to the previous version.

If you can, now restart the computer once the process is complete and check if the issue is solved or not. If the problem still persists, update the driver.

Note: A few of the following steps, such as downloading the latest firmware version may not work on your PC since it is facing problems connecting to the internet. So, perform them on another PC with an internet connection. Then, copy the downloaded file to the problematic system via USB.

  • Follow the same steps as above in the problematic PC to find and right-click on your network device and go to the Driver tab.
  • Check the Driver Version and note it down.

Checking the Driver Version

  • Minimize the Device Manager window.
  • Now, open your web browser on another PC with an internet connection.
  • Go to your manufacturer’s website.
  • Search for the latest driver for your device. Tally it with the driver version you noted before.
  • Download the latest driver, install it, and save it.
  • Copy it in a USB storage and transfer it to the problematic device.
  • Now, maximize the Device Manager window in the problematic device.
  • Right-click on your network device.
  • Select Update driver from the dropdown options.
