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

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

    Hi,

    I have a Surface Pro 3

    I have had slow wifi since installing Win10. Advice from technical support, run a Windows Media Creation tool to 'update' my Win10 cleanly without losing my files or apps. This made no difference.

    I have tried a 'two fingered' reboot - no difference

    I have tried 2.4 and 5 bands only - no difference

    My Marvel wifi adaptor driver version is 15.68.9032.47 - which apparently is the latest

    If I use an ethernet cable my download speed is ~60Mbps. On wifi its 10Mbps. Using Win8.1 on wifi it was 55Mbps. As a control, I have a Dell laptop right next to the Surface on my desk and it also gets ~55-60Mbps, so its no issue with the router.

    Please can anyone help?????

    Joe

    I got a Surface Pro 3 less than a month ago.  So far I have installed a few aftermarket programs (iTunes, Firefox, Chrome) and the 1yr subscription to Microsoft Office 365 that came with my computer.  I also created a homegroup on my home wifi network.  Other than that, the computer is precisely the same as it was out of the box. 

    For the last few days, I am having some severe internet/network connectivity and operating issues.  Google Chrome, which I usually use to browse, is extremely slow to open.  When that happened, I tried to use both Firefox and Microsoft Edge.  Both of those programs opened, but were very slow to open pages, and often timed out. 

    I tried to see if the homegroup was the issue, but under to settings/network & internet/homegroup it stated i was not in a homegroup.  Running the homegroup troubleshooter and network troubleshooter did not fix the issue.  When I tried to click on "network and sharing center" window opened blank, and it took minutes to load.  I opened another computer, right next to the SP3 and was able to access the internet and the homegroup without issue, so I know it is not a network issue. 

    Eventually, when the internet options window I opened froze and would not respond, I restarted the computer and was able to access the internet.  Using the machine later, the same problem happened again.  Restart, and it fixed it again. 

    Is this a known issue, and are there any fixes available?  I do not want to own a machine that requires random restarts to function properly. 

    Thanks
