Symptoms:

When you use a Windows 8.1 or Windows 10-based Surface Pro 3 or Surface 3 and connect to a wireless network on a 5 GHz wireless channel (channel 36 and higher), the following issues may occur:
- Slower throughput when it is connected to 2.4 GHz wireless connections, compared with 5 GHz wireless connections.
- Network performance is decreased or appears to get worse over time.
- Can't authenticate to a wireless network by using Enterprise security.

Note:

- These issues may not occur consistently.
- Disconnecting and then reconnecting to your wireless network may stop the issue from occurring.
- If you're connected to a 2.4 GHz wireless network (channels 1 to 13), and you're having any of the issues that are listed above, this hotfix doesn't apply to your problem, because this article is specific to 5 GHz wireless connections (channel 36 and higher).
- Also, if you are running Windows 10 Version 1511, this hotfix doesn't apply to your problem.

Cause:

- These issues occur because the Marvell wireless adapter driver version 15.68.3091.193 (originally released on Surface Pro 3 and Surface 3) may sometimes manage 5 GHz connection speeds incorrectly, and this may cause inconsistent throttling of the wireless connection.
- Please notice that multiple factors can influence wireless network connectivity and throughput, including but not limited to: Environmental factors such as heavy machinery or load-bearing structures, Wireless Access Point/Router firmware revisions, Wireless configuration settings in use, software that is running in Windows, and proximity of other sources of electromagnetic (EM) signals.
- We recommend that customers troubleshooting wireless issues by isolating as many variables as possible in order to ensure successful resolution to their issues.

Resolution:

- Windows 10 users can upgrade to Windows 10 Version 1511. This will install Windows 10 Marvell Wi-Fi driver version 15.68.9032.47, which will fix the issue. Surface Pro 4 and Surface Book already have this driver.
- For Windows 10 customers who can't upgrade to Windows 10 Version 1511, the hotfix package will install driver 15.68.9032.47 to fix the issue. This driver uses a Windows 10 driver model and can't be installed in Windows 8.1.
- For Windows 8.1 customers, the hotfix package will install Windows 8.1 driver 15.68.3093.197 to fix the issue.
