This issue first appeared in the Microsoft forums, where a Surface Pro 4 owner explained that during a Speedtest.net test the internet connection jumped from 17mbits and it then dropped down to less than 2mbits. User JymMuller also detailed that he has a Comcast Wi-Fi dual-band modem with speeds up to 150mbits. On a reply, Joe a Microsoft employee revealed that is a known issue on Surface Pro 4 tablets where owners will notice slow 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.” Joe recommends to never roll back your Surface Pro 4 wireless adapter to a previous version. The tablet includes a new driver technology called WDI for Windows 10 and non-WDI drivers won’t work correctly. As such, if you have a Surface Pro 4 and you’re experiencing slow wireless connectivity, you can try the following workaround.
Boost Surface Pro 4 Wi-Fi connectivity
If everything works as expected, your slow connectivity should be resolved and you should now see an improved wireless connection. Of course, this isn’t a permanent solution, but we hope Microsoft releases an updated set of the driver through a firmware update soon to permanently fix the slow Wi-Fi issue on Surface Pro 4 tablet and possible Surface Book laptops.
