In an answer to a question on Microsoft Answers, a Microsoft Support Engineer has 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.
The workaround suggested is as follows:
From the WinX Menu, Run regedit to open the Registry Editor:
Navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897
Look for the key called TXAMSDU.
Double click or tap on it.
Now modify its value from 1 to 0.
Exit the Registry Editor and restart your device.
