Surface Pro 3 - Windows 10 - WiFi (slow or limited connectivity )

Anonymous

Have a Surface Pro 3 that worked fine till I updated to Win10.  Now the wireless connection seems to randomly go to a "limited connectivity" mode.  Fortunately was purchased from Costco a coupe of weeks ago so it is going back there if we can't get this figured out by Sunday.

The Surface Pro3 is a flagship device - why in the world would you subject your customers to have to resort to looking for help in forums like this?

Everyone,

Build 10586 - the November Windows 10 update - was released yesterday, and it contains a newer Marvell wireless driver 15.68.9032.47 - people are reporting that this greatly improves wireless connectivity. Please download the large update, and if you used the registry hack, reverse it as follows:

Press Windows button. Search for regedit. Open it

  1. Navigate to the following path:

 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897

  1. Find the item labeled “TXAMSDU”. Double tap and modify the value from 0 to 1
  2. Restart the machine

Then test your connectivity, and post results.

Fred,

the November Windows 10 update to build 10586 has new wireless drivers. Can you download and install the update (it should be offered via WU) and let us know if this changes your connectivity?

Penny,

These kinds of issues WERE present on 8.1 for months but they mostly all cleared after several driver updates.

And that particular router is not one known to exhibit slow wifi. I'm suggesting you trade it because it is SP new and you can now get one with 10 pre-installed and not have to go through an upgrade AND because you have this issue. Getting it swapped will rule out a hardware issue and would be a step forward.

This is what *I* would do if in this situation.

For what it's worth - Microsoft needs to fix the driver and any underlying Win 10 OS issues. It took them 9 months to get a "good" Windows 8.1 wireless driver. For now, consider an external USB wireless adapter. I carry around a http://www.amazon.com/Edimax-EW-7811UTC-Dual-Band-Connectivity-Exceeding/dp/B00FW6T36Y

    Hello Trytolovewindows

    You can also find threads on wifi and audio problems with good steps within these forums.

    If you continue to have trouble, head back to the Store that set you up with this replacement Surface so they can get you back up and running.

    Best regards 

    Thanks for your suggestion. I went back to the store yesterday, because many apps stopped working. I went to the store and they try to reset it but failed. They gave a new one to me again. As you expected, the wifi and audio issues are still there. I am holding it until your company find out a solution. I feel bad for MS. Windows 10 works perfectly on my Dell xps 13. They did a very bad job on their only hardware! Tell you a story, when I call "he Cortana" while SP1 and xps 13 are all on the tale, only my Dell laptop response.  As I said before, the windows preview works even better. I never had any wifi issue with any build of preview.

    Split from this thread.

    My Surface Pro 3 WiFi worked fine until about mid-July when, following an update, the speed between the Surface and my router dropped from an average of 300Mbs to a maximum of 72Mbs. It took me all night and half a dozen restarts to download Windows 10. I have tried updating the driver for the WiFi adapter, but my system reports that I have the latest version; uninstalling it and re-installing it has no effect. There does not appear to be any earlier version of the driver. In desperation, I contacted MS Support here in Australia who took me through the same process and then got me to switch Band on the adapter from Auto to 5Ghz only, which caused me to loose the internet connection and the on-line support. I haven't heard anything since and my WiFi is still a maximum of 72Mbs. 

    Any suggestions?
