Windows 11 Dev Build 26120.1912: Enjoy 6GHz Wi-Fi Tethering and Enhancements

In a world perpetually connected via high-speed internet, Microsoft has just rolled out the latest Windows 11 Dev Build 26120.1912, and it's an update that promises to leave tech enthusiasts buzzing, as it brings with it the much-anticipated support for 6GHz Wi-Fi tethering. This new build shines a spotlight on enhanced connectivity and user experience, catering to the needs of modern Windows users who crave faster and more reliable internet connections.

What's New in Build 26120.1912?​

This update isn't just a minor tweak; it introduces a variety of features aimed at making the user experience smoother, particularly with mobile connectivity. Here’s what you can expect:

1. 6GHz Mobile Hotspot Support​

For the first time in the Windows 11 ecosystem, you can now take advantage of 6GHz tethering—provided your hardware is up to the task. This feature enhances the Windows Mobile Hotspot functionality, allowing devices that support this band to share faster internet connections. Users can find this under Settings > Network & Internet > Mobile Hotspot, provided they have the right chips and updated drivers installed.

• What to Keep in Mind: While the tantalizing allure of 6GHz is hard to resist, not all hardware that claims 6GHz support will necessarily function as a mobile hotspot. Compatibility matters!

2. General Improvements​

Beyond the spotlight feature, this update includes various general improvements and bug fixes that aim to enhance the overall experience on Windows 11. Though specific details on all fixes remain scarce, enhancements were made in several sensitive areas, ensuring users face fewer headaches as they traverse the OS.

Noteworthy Fixes Include:​

• Adjustments to Task Manager functionality and its settings page.
• Resolved a few common memory leaks associated with the Input Method Editor (IME), which could affect overall system performance when certain apps were in use.
• Enhancements related to stability and usability for WebView2 apps.

3. Known Issues​

Unfortunately, every update has its quirks. Current known issues with Build 26120.1912 include:

• Clicking on letters in the Start menu’s All Apps list may cause the list to malfunction, requiring a reboot or restart of the explorer process.
• Users may encounter a white background issue in Task Manager settings, veering slightly off from the intended design during high contrast mode toggles.

Why 6GHz Matters?​

The inclusion of 6GHz in Windows 11 is more than just a numerical upgrade. In the realm of Wi-Fi, the 5GHz band has long been standard, but with more devices vying for bandwidth, it can become congested. The introduction of the 6GHz band allows for greater data throughput, reduced interference, and thus, faster download and streaming speeds.

What is 6GHz Wi-Fi?​

To dive deeper into the technicalities, the 6GHz band is part of the Wi-Fi 6E standard. It offers more frequency blocks, reducing congestion and improving performance:

• Higher Speeds: Ideal for bandwidth-heavy applications like 4K/8K streaming and online gaming.
• Increased Capacity: More channels mean more devices can operate simultaneously without a noticeable dip in performance.

This isn't just a win for heavy users; even casual browsers will benefit from cleaner connections and faster speeds.

How to Access the Update​

For Windows Insiders eager to experience the new build, navigating to Settings > Windows Update and clicking "Check for updates" will pull in the latest features. Just remember, only those on the Dev Channel will have access to this build.

The Future of Windows 11​

As Windows 11 continues to evolve, the integration of technologies like 6GHz Wi-Fi tethering paves the way for more robust connectivity solutions. This also exemplifies Microsoft’s commitment to keeping abreast with the times, ensuring Windows remains at the forefront of modern computing technology.
As enthusiasts and professionals alike download this new build, they should do so with the knowledge that they are part of a transformative moment—one where gaming, streaming, and a host of other data-heavy activities can be undertaken with speed and efficiency previously reserved for the idealized age of Wi-Fi.
So gear up and get ready to surf the web like never before—your high-speed adventure awaits with Windows 11 Dev Build 26120.1912!
