Common VPN Issues in 2024

Introduction

In July 2023, Microsoft released the optional cumulative update for Windows 11, version 22H2. This update addresses various issues, including some that affect VPN performance and display or audio devices. The update, known as KB5028254, is a monthly non-security preview release that allows Windows administrators and users to test improvements before the official August 2023 Patch Tuesday release.

Fixes for VPN Performance and Display/Audio Devices

The KB5028254 update includes fixes for 27 issues, including those impacting VPN performance and display or audio devices. One of the issues addressed is related to excessive Address Resolution Protocol (ARP) requests to the network gateway. This problem occurs when the VPN is on a wireless mesh network using an aggressive throttling algorithm, leading to poor network performance. Microsoft’s update aims to resolve this issue and improve VPN functionality.

Another issue that the update tackles is the disappearance of audio and display devices after systems resume from sleep. This can be frustrating for users, but the KB5028254 update provides a fix for this problem, ensuring that the devices no longer disappear.

Improved Brightness Settings and Widgets Functionality

Apart from addressing VPN and device-related issues, the July 2023 optional cumulative update also brings improvements to brightness settings and Widgets functionality. The update makes brightness settings more accurate, allowing users to adjust their display brightness more precisely.

Additionally, the update ensures that Widgets no longer unpin from the Windows taskbar unexpectedly. This enhancement provides a smoother and more reliable experience for users who rely on Widgets for quick access to information and applications.

Optional Non-Security Update

It’s important to note that the KB5028254 update is an optional monthly non-security preview release. Unlike Patch Tuesday releases, which include security-related fixes, this update focuses on addressing specific issues and improving the overall performance of Windows 11, version 22H2. Users can choose whether to install this update based on their needs and preferences.
