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

    Perels, complete sympathy!!! so frustrating. I didnt want to go down the Apple route and get an ipad, as I am familiar with windows and wanted a tablet/laptop alternative. But this has really pushed me the other way. Another issue I have is the complete lack of USB GPS receiver support (because MS were too tight to put a GPS onboard). Issues with comm ports and Win8.1 not able to emulate correctly blah blah. Just sort it MS. Then offer it at a rip off price, but at least give a solution. I mean, a tablet these days without an option for GPS - beggers belief!

    Jollyjoe73, thanks for replying. I actually own an iPad 2 - no problems whatsoever here. Also, I have another laptop with 80211 AC wifi - no problems here. In fact, all the problems I have are only related to Surface Pro 3. The "change/try with a different router" is just stalling / avoiding the real issue. I think Microsoft is well aware how much trouble the SP3 is in. This thread is almost 400 posts, 6 months old and similar threads are found everywhere on the internet.

    To me it looks like this: Microsoft is well aware of the problems with Wifi SP 3 but won't admit them as they are then forced to do a massive (and expensive) product recall. Instead, the direct people to forums, ask them to reinstall/reset, try updating etc. Nothing works. Class action lawsuit anyone?

    For anyone interested please see this post I did almost a year ago, http://answers.microsoft.com/en-us/surface/forum/surfpro3-surfhardware/surface-pro-3-problems-with-wifi-and-bluetooth-how/fff9e3dc-f12c-4231-93f6-4ffb948d54d9

    I've asked umpteen times for a list of routers and have not gotten a reply. And yes, it is only the Surface 3/Pro 3/Surface Pro 4/Surface Book with the Marvel wireless AC chip that has this issue (and other devices work just fine).

    IMO, Microsoft does not properly test drivers. Or worse, they release with these known issues.
