Introduction

The release of Windows 11 version 24H2 was anticipated to bring a suite of enhancements and performance improvements. However, a significant number of users have reported encountering severe connectivity issues post-update, affecting both internet access and network functionalities.

Background

Windows 11 24H2, part of Microsoft's semi-annual update cycle, aimed to introduce new features and bolster system performance. Despite rigorous testing, the update has led to unexpected connectivity disruptions for many users.

Reported Connectivity Issues

Internet Connectivity Disruptions

Users have reported that, following the 24H2 update, their devices fail to obtain valid IP addresses, resulting in the assignment of automatic private IP addresses (APIPA) starting with 169.x.x.x. This misconfiguration prevents both wired and wireless connections from accessing the internet. Efforts to update network drivers, reset network settings, and reinstall network adapters have often been unsuccessful. (pcworld.com)

Network Sharing and Discovery Failures

Post-update, some users have experienced difficulties with network sharing and device discovery. Devices fail to appear in network lists, impeding file and printer sharing capabilities. This issue is linked to the Function Discovery Resource Publication (FDResPub) service not starting automatically. Manually setting this service to 'Automatic' startup has provided a temporary solution for some users. (answers.microsoft.com)

Scanner Connectivity Problems

The update has also affected USB-connected scanners utilizing the eSCL (eScanner Communication Language) protocol. Users have reported that their devices are no longer recognized by the system. Microsoft has acknowledged this issue and is working on a resolution. (learn.microsoft.com)

Implications and Impact

These connectivity issues have significant implications:

  • Productivity Loss: Users reliant on stable internet and network connections for work or education face disruptions.
  • Operational Challenges: Organizations may encounter operational inefficiencies due to network sharing and device connectivity problems.
  • User Frustration: The recurrence of such issues can erode user trust in system updates.

Technical Details and Workarounds

Internet Connectivity
