[平板] surface pro 4 / sp4 wifi 太慢問題

作者: VdustR (京)   2016-05-27 06:55:30
我的設備是 surfae pro 4 i5 256g
一直都是使用 wifi 上網
可是速度在連同樣的分享器的狀況下慢手機很多
剛剛看到這篇

剛剛測試覺得好像有差 (在想是不是心理作用 XD)
不知道有沒有人有分享過
搜尋 surface pro 4 / sp4 wifi 沒有看到類似文章
所以貼上來給大家看看~
方法是打開註冊表 (win + s 輸入 regedit 後按 enter)
找到位址 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897
將 TXAMSDU 由 1 改為 0
如圖: https://i.imgur.com/hTNQD5i.png
然後重開機就可以了~
希望對大家有幫助 :)
內文有提到原因如下:
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
