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

    Hey Barb,

    Setting the 5GHz channel to 20MHz bandwidth has allowed me to use 5GHz again, albeit only at 78Mbps maximum. Thank you for the suggestion, I hope MS resolve this issue quickly - it seems the SP3 has been plagued with wireless issues since it was released and only recently were these resolved, only to be broken again!

    >>I'm having the exact opposite issue. I have an asus dual band router (firmware up to date) and when using 5GHz and run speedtest, it fluctuates between 1mbs and 8mps. It's really slow. After reading this thread, I figured I'd try the 2.5GHz and now I'm getting 75mbs. So strange. There has to be something wrong with the wireless adapters in these things. I just bought it this week, ran all updates including firmware, installed Windows 10, then ran update and firmware again. It's all up to date, but the wifi network adapter is definitely not fixed

    did you have this issue before you upgraded to 10?

    you said you just bought the SP3. I'd return it for a refund and purchase again.

    Microsoft and others are selling with Windows 10 pre-installed. If you are near

    a physical Microsoft Retail Store, you can go there and they will swap. There

    ARE some folks that are having issues with Windows 10 and 5GHz. Not everyone is

    affected.

    Which ASUS router? where did you buy your SP3?
