Wi-Fi Networks Disrupted by Windows 11 Update
Have You Installed the December 2023 Windows 11 Update? Here’s How It Affects Wi-Fi Networks

If you’ve installed the December 2023 Windows 11 update, you might notice that it causes issues with Wi-Fi connectivity. Keep reading to understand these problems and learn how to fix broken Wi-Fi networks in Windows 11.

What’s in the December 2023 Windows 11 Update?

This update includes new Intel, AMD, and Realtek drivers. However, the patch notes lack detailed explanations of these changes, leaving many tech professionals speculating about their impact. If you don’t require the graphics driver updates, it may be wise to delay this update to avoid potential Wi-Fi issues.

That said, the update also includes some security improvements. Microsoft refers to these updates as “miscellaneous” but does not provide specifics in the documentation.

Wi-Fi Problems Caused by the Update

The update affects your adapter’s ability to connect to Wi-Fi networks, but the issues aren’t uniform across all networks. For example, while you might connect to your home Wi-Fi without trouble, your adapter may struggle on enterprise, public, or educational networks.

The problem is particularly pronounced for networks using 802.1x authentication, a common standard in enterprise and institutional environments. Many professionals suspect the root cause lies with outdated Qualcomm wireless adapters, widely used in devices in educational institutions and public organizations.

Fixing Windows 11 Wi-Fi Connectivity Issues

If you encounter Wi-Fi problems after the update, try these two troubleshooting methods:

1. Disable 802.11r

The 802.11r feature allows faster roaming between networks when signals drop. However, it appears linked to the connectivity problems caused by the December update. Disabling 802.11r on affected networks may resolve the issue.

Keep in mind: Disabling 802.11r can cause other problems, such as poor roaming performance on mobile devices. Given the minor improvements it offers in this situation, this solution is not ideal.

2. Use Known Issue Rollback (KIR)

Microsoft offers a better solution through its Known Issue Rollback (KIR) feature, designed to address non-security bugs introduced by updates.

How KIR works:
- KIR stores the previous version’s code, allowing Windows to revert to it if issues arise.
- The system dynamically determines whether to use the old or new code based on updated policies.
For end users, this process happens automatically: Microsoft updates the settings in the cloud, and the fix is applied the next time you restart your computer. Note that the rollback may take up to 24 hours to fully resolve the issue.

For enterprise users: Administrators can deploy a special group configuration to expedite the resolution.

Conclusion

Although the December 2023 Windows 11 update introduces Wi-Fi issues, these problems can be resolved. You can disable 802.11r for a quick but imperfect fix, or rely on Microsoft’s Known Issue Rollback feature for a more robust solution. A simple system restart, with some patience, should restore your Wi-Fi connectivity.

Is a VPN Necessary? Your Guide to Staying Safe Online
With online scams and privacy concerns on the rise, virtual private networks (VPNs) are becoming an essential tool for everyday internet use. The growing number of VPN advertisements on podcasts and other media platforms is a clear indicator of their increasing popularity.

You’ve probably heard about VPNs but might not fully understand how they work. In simple terms, a VPN establishes a secure and private connection for your internet activities. This allows you to browse anonymously, protect your data, and access content as if you were in another location.

Perhaps you’ve used a VPN for work or school to access remote networks. But have you ever considered its value for personal use? The short answer is—yes! Let’s explore why VPNs are crucial and how to choose the best one for your needs.

How do VPNs work?

VPNs function by creating a secure “tunnel” for your internet traffic. Here’s a breakdown of their five key components:
1. Encryption: This process converts your data into a coded format that only authorized parties can decode, ensuring your information stays secure during transmission.
2. VPN servers: These servers, located worldwide, act as intermediaries between your device and the internet. They mask your IP address and location, enhancing your online privacy.
3. Kill switch: This feature automatically disconnects your internet access if the VPN connection is interrupted. It ensures that your data is never exposed.
4. Split tunneling: This option lets you choose which internet traffic routes through the VPN’s encrypted tunnel and which connects directly to the internet.
5. VPN protocols: Protocols like OpenVPN, IKEv2, and WireGuard dictate how your data is transmitted. Each is optimized for different use cases, such as streaming, gaming, or mobile device usage.
Why use a VPN?

Even if you already use other cybersecurity tools, adding a VPN significantly enhances your protection. Here’s how:

Privacy protection

VPNs create a secure tunnel that keeps bad actors from intercepting your activity and sensitive information. This is especially critical when using public Wi-Fi networks in coffee shops, airports, hotels, or malls. These networks are often unsecured and vulnerable to hackers looking to exploit weak security protocols.

Enhanced cybersecurity

While antivirus software is essential, a VPN offers complementary protection:
- Antivirus software defends your device against malware, viruses, and malicious software.
- VPNs encrypt your internet connection, making it nearly impossible for ISPs, hackers, or government surveillance to monitor your activities. This ensures your browsing history and personal data remain private and anonymous.
Secure public Wi-Fi use

Public Wi-Fi networks are notorious for their lack of security. Here’s how a VPN makes a difference:
- Antivirus software can block malicious files and websites but doesn’t secure your internet connection.
- VPNs encrypt your data on public networks, preventing hackers from intercepting sensitive information like passwords, financial details, and personal messages.
Accessing restricted content

A VPN is also your gateway to accessing content that might be restricted in your region. For example, a friend of mine loves British television but lives in the U.S. By using a VPN to set her virtual location to the UK, she can enjoy her favorite BBC murder mysteries without any restrictions.

For frequent travelers, VPNs are invaluable. If you find yourself in a country with strict censorship laws, a VPN allows you to bypass these restrictions and access your usual websites, social media, and streaming services.

Which VPN should you choose?

When selecting a VPN, keep these factors in mind:
- Connection speed: Ensure the VPN offers fast and reliable connections, especially for streaming or gaming.
- Unlimited data and bandwidth: Avoid VPNs with data caps, as they can interrupt your browsing experience.
- Server locations: A wide range of server locations ensures you can access content from different regions.
- No-log policy:* Choose a VPN that doesn’t store your online activity to maintain your privacy.
- Security features and protocols: Look for advanced encryption, kill switches, and support for secure protocols.
- Ease of use: A user-friendly interface is crucial, especially for beginners.
- Brand reputation and customer support: Opt for well-reviewed providers with reliable customer service.
While free VPNs exist, they often come with limitations like slower speeds, data caps, and weaker security measures. Investing in a reputable paid VPN is worth the added protection and performance.

What steps should you take next?

As cyber threats continue to evolve, safeguarding your private data is more important than ever. A VPN is a vital addition to your cybersecurity toolkit, ensuring safe and private internet usage. Consider trusted solutions like Webroot™ Secure VPN to protect your sensitive information and enhance your online experience.

A no-log policy ensures that the VPN provider doesn’t store any records of your online activity. This commitment to privacy reduces the risk of data breaches, prevents third-party tracking, and builds trust, giving you peace of mind that your actions remain confidential.
