Tip: how to fix a slow Wi-Fi connection on Surface Pro 4 or Surface Book

Surface Pro 4

The recently released Surface Pro 4 and Surface Book have generated waves of interest, but the devices have not been without problems. Some owners have complained about flickering screens, while others have experienced issues with charging.

There are also some users who complain that their wireless connection is much slower than other devices. If you are one of those affected by the problem, a simple registry hack is all that's needed to get things back up to speed again.

Microsoft is aware of the problem, and has pinpointed the issue to a few specific access points. Writing on the Windows Answers support forums, the company said: "We have a known issue with .41 that results in low throughput with specific access points. The issue is specific to MAC layer aggregation (AMSDU over AMPDU) and only impacts a small subset of access points. We are working on a fix for an upcoming update. Until the fix is available, please update the registry key setting to work around this issue".

  • If you have noticed this issue, try the following to see if it helps:
  • Press the Windows key and R at the same time, type regedit and press Enter to launch the Registry Editor.
  • Navigate to KEY_LOCAL_MACHINE\SYSTEM\ ControlSet001\Services\mrvlpcie8897.
  • Locate the key named TXAMSDU.
  • Double click it, and change its value to 0.
  • Restart your computer.

Let us know how you get on!
