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 Barb,

    I would like to weigh in on this as I have run into this issue as well. 

    We have a mixture of surface 3 and surface pro 3 devices running windows 8.1 and windows 10.  The have the 15.68.3091.193 version of the Marvell AVASTAR Wireless AC driver.  All devices are using the same driver.  We have a mix of 40 buildings with Cisco 1142, 3500, 2600 and 2700 APs.  The 1142, 3500 and 2600 are all 802.11n APs, but the 2700's are 802.11ac APs.  All of these APs are running the same version of code as they are controller based.

    We are finding, like many others, that when we connect to APs, if we force the driver to 2.4 GHz then everything works fine. 

    Here is another issue we have discovered.  The surface 3 and pro 3 has an 802.11ac card in it.  Most of our APs are 802.11n.  With this driver version, regardless of windows 8.1 or 10, we have the 5 ghz issue.  However, if we connect to an 802.11ac AP, we have no issues.  It is almost as if this driver has a backward compatibility issue with 802.11n on 5 GHz.

    Just some food for thought.
