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

    First, MVP's/Community Moderators are unpaid volunteers and customers just like

    you. When I advise someone to try with a different router, I have the best

    intentions - it is a diagnostic to see if the problem occurs on one router or

    ALL routers. Asking people to try a different router pinpoints where MICROSOFT

    has failed to do proper testing and with specific brands and models highlighted

    in this kind of "triage" - it is up to Microsoft to test/respond, etc.

    If the problem IS a specific router, the only advice *I* can give is to try a

    different router or purchase a USB wifi adapter. Both of those solutions are not

    acceptable, but if someone's wifi is so poor as to be unusable, it is currently

    the only solution, absent a fix from Microsoft.

    I've tried to get Microsoft to officially respond to these wireless issues here,

    but obviously that has not been successful.

    I personally travel with a USB wireless adapter (although I have good

    connectivity at home) because I want to be prepared when I encounter

    connectivity issues at a friend's house, etc.

    I'm not stalling or trying to avoid the issue.

    My router model is Technicolor MediaAccess TG788vn v2 (firmware 10.5.2.S).

    I have connected a Microsoft Wireless Mobile Mouse 6000 via bluetooth dongle. Wifi speed is greatly slowing down when the Surface Pro 3 is close to the Wifi dongle / mouse is in use. As suspected, SP is a poorly designed product not able to shield itself properly from bluetooth frequency interference and thus not able to honour its promises.

    A couple of things - Wireless 2.4GHz (b/g/n) shares the same channels as Bluetooth. This isn't a Microsoft thing, it's a consequence of how these protocols were established. You can search for information that explains this. You MIGHT get some relief by configuring your TG788vn for a specific channel/change the channel, etc. You WILL have better performance if you got yourself a newer 802.11ac router and configured it as an access point, connect it to your router and connect to the 5GHz SSID.

    You mentioned a similar issue in this discussion thread 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 know you don't want to hear a suggestion to spend money/buy a different router, but in this case, Bluetooth vs 2.4GHz WiFi isn't just a problem with the Surface. Lot's of other things that operate in the 2.4GHz band cause issues with 2.4GHz WiFi - older cordless phones, microwaves, etc.
