Hello Windows Insiders,
After the release of build 14915 to to the Fast ring for PC yesterday, a Wi-Fi bug has been discovered that is impacting a subset of users. Please review the following:
- Surface Pro 1
- Surface Pro 2
- Wi-Fi adapters using early Marvell drivers
- Various USB-based WiFi adapters
- (There may be other similar drivers affected, research is ongoing)
The percentage of users impacted is limited, but for those affected, all Wi-Fi functionality is lost and there is no temporary fix to restore Wi-Fi on this build given the nature of the bug. Affected users will need to use a wired connection if available or roll back to the previous OS version on their device to bypass this issue.
Our Engineering teams have quickly completed a root cause analysis of the issue and are working to get the fix checked-in to make it available in our next flight.
Thank you as always for the feedback that has been provided and for the quick efforts to share this issue with us.
