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

    The weird thing is I've seen other people complain about the problem on Netgear and Linksys routers. You could say the common thread is newer 802.11ac routers, but this thread began with someone who uses an 802.11n router. Who knows?

    So I'm trying to factory reset mine and see if that helps. It has said "Resetting this PC 1%" for a couple of hours now. Makes me nervous cause I don't want to shut it off, but it doesn't seem to be making any progress. Going to give it the rest of the night and see if patience pays off...

    New Surface pro 3 on windows 10. I am having the same issues, I have done all of the updates, uninstalled re-installed wireless drivers here's the thing we all have in common... I am using an ASUS router too.  RT-AC87R  I get 90 Mbps down on speedtest.net on 2.4 GHZ and when connected to 5 GHZ I get 1.5 Mbps down (if it even stays connected long enough to test).  I have updated my router firmware as well, same result.  I do not think this a coincidence that we all have ASUS routers and have this issue.  

    Playing around on the router admin page with the 5Ghz settings, I changed The setting from "auto" to "N only" and it worked on 5Ghz I was getting about 50Mbps down.  For now I switched it back to auto and then just reconnected with 2.4Ghz the speeds are still 90 Mbps down which is what I get on my other devices that connect to 5 Ghz. 

    Update: More things I have tried:

    Restored to factory and reinstalled windows 10.  Re downloaded and installed all the updates then tested.. same result.

    Exchanged the Surface Pro 3 at Best Buy for another one, same result.
