Stop Firewall from Blocking Wi-Fi

You may encounter a message “your Internet access is blocked” when you try to visit certain websites. This is basically an error message caused by Firewall or an antivirus program installed on your device.

Annoying as it may, there is nothing to worry about because there are some easy and quick fixes to this error.

In this article, you will learn about the causes along with the methods and steps to follow for each in order to remove internet blocking.

KEY TAKEAWAYS

  • Wi-Fi may be blocked by Firewall as a security measure when it assumes there is a threat to the system from the internet traffic.
  • A simple solution to the Wi-Fi being blocked by Firewall is to update the firmware of both the router and the modem.
  • Sometimes simple fixes like rebooting the system and turning off the built-in protection in Windows temporarily may resolve the issue.
  • Unchecking the HSS DNS leak rule in the permissions options for Firewall is also an effective solution to this issue.
  • You may install an antivirus program that is better and can bypass the default Windows Defender Firewall automatically.

Why Does Firewall Block Wi-Fi?

Usually, Firewall and antivirus programs are configured in a specific way to prevent any potentially harmful apps or programs getting into your PC.

So, as a process, it may block your Wi-Fi and, in turn, the internet to prevent website spoofing, phishing scams, ransomware, viruses, and malware from entering into the system through the internet.

The primary purpose of it is to protect user data, information, files, folders, privacy, and functionality of the system.

It is basically a network security device. It monitors all incoming and outgoing traffic and determines whether a specific traffic is to be blocked or allowed, based on a precise set of parameters and security guidelines.

However, while configuring it, a few exceptions may be made, such as the email client or the browser may be excluded from the Firewall exceptions list, which might cause this error.

Also, it may misinterpret signals and decrypt Wi-Fi traffic as a threat, which may lead to this particular issue.

A few other reasons for your Wi-Fi to be blocked by Firewall are:

  • Malware or viruses
  • Conflicting apps and antivirus programs
  • Issues with network drivers

Irrespective of the reason for this issue to occur, here are some easy and effective solutions for it.

How to Stop Firewall from Blocking Wi-Fi?

One of the most effective ways to prevent Firewall from blocking your Wi-Fi connectivity is to disable it from the System and Security in the Control Panel.

There are also a few simple checks to make to ensure your internet connection is okay, before you start with the more advanced solutions.

More often than not, these simple checks can be the potential fix to the issue of the Firewall clocking your Wi-Fi connection.

These actions will eliminate other internal issues causing this error. These are:

  • Rebooting your PC
  • Restarting your modem and router
  • Switching on to a LAN connection from Wi-Fi to check issues with connectivity
  • Booting your computer system to Safe Mode with networking and connecting to the internet again
  • Running the built-in Windows troubleshooter to identify issues with the network and fix them automatically
  • Updating the firmware of your modem and the router
  • Running a Firewall reset command in the Command Prompt

Now, when the above checks and solutions cannot resolve the issue, here are some more effective methods to rectify the Firewall blocking the Wi-Fi error.

The steps to follow for these methods and some of the above simple methods are explained in detail for you.

Note: For all these examples, it is assumed that Windows Firewall is used and not Avast or any other third-party software. Also note that the settings and interface of Firewall may vary but the general process is the same.

And finally, be informed that disabling Firewall from your system for a long time may cause severe virus infection and other threats.

So, exercise extreme caution while performing a few particular solutions mentioned below.
