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

    I came home today and found another update which is ostensibly from yesterday.  Turns out there was a hardware and firmware update from 9/29 and I had only gotten one of them despite multiple update attempts.  See screenshot below.  I updated again and it still didn't fix ****.  Oh well, at least MS has the existence of the update acknowledged out on their firmware history page (which wasn't true yesterday).  Now they just need to post the firmware to the manual download page so I can waste more hours trying to get my wifi working.  That and maybe actually fix this problem.

    John1F... thanks for your insider information.  But surely you realize how ridiculous it sounds to ask us to "know that the investigation continues" on a product which has been out for a year and is about to be replaced by the SP4?  What assurance is that supposed to be?  This "investigation" should have been done 1.5 years ago.  My wifi has been barely functional for a whole year of owning this supposed flagship product.  Think about that and what it says about the quality story that your company is offering the customer.  The ping screenshot below to my LAN's gateway tells the whole story you need to know about my experience with Microsoft's SP3.

    Hi

    I went back to WiFi driver version 15.68.3073.151 and WLAN latency is solved. Everything works fine so far.

    With the newer Windows 10 drivers PING time on my Surface Pro 3 to local gateway where around 400ms then down to 30ms then up to 400ms again. Using Skype for Business VoIP was a pain, showing bad network quality. 

    With 15.68.3073.151 driver Version PING is down to less then 5ms.

    I tried on different WLAN Access Points (ASUS RT-AC68U and Cisco WAP4400N and a portable WiFi to UMTS Bridge) with the same problem of high PING time. So it seems not to be specific to a WLAN Router manufacturer, but a Surface problem. It did not show packet loss but this high PING time.

    However maximum WLAN connection speed is around 144 MBit/s whereas with other Notebooks I get 300 MBit/s connected to the same WLAN with high signal quality.
