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,

    Here are my response:

    1.  version and build #:  Version 10.0, build 10240

    1. the problem started when I upgraded from Windows 8 to Windows 10 last

    year.  the internet connections became slow.  I have been consuolting

    Microsoft Forum and the Microsoft Twitter account, and even called

    Microsoft Support Team in our country.  All advice which ranged from

    tweaking the registry to rebooting, resetting, turning off location.  None

    of those worked.  The Microsoft Support in the Philippines even advised me

    to send my unit to Singapore because they do not have service center for

    Surface in the Philippines.   Those were indeed frustrating.  Imagine

    yourself owning a  very expensive machine with very slow connections and no

    one is giving you a solution.

    a.  the connection is slow anywhere

    b.  this is not just at Home.  In the office, at cafes, in hotels, in

    portable wifi.  Anywhere.

    I am sorry if I said "rubbish" out of my frustrations. I hope you can help me

    with this problem once and for all.

    Thanks,

    Noel

    By the way, when I sent this message through email, I received a message that says the message cound not be delivered to microsoftanswers@microsoft.com because the remote server is misconfigured. So I am sending my response through the forum.

    1. what version of Windows? run

    winver

    and post version and build #

    1. tell us when this started and supply details -

    a. is it slow everywhere or just at home?

    b. if just at home, details of your router setup - dual band? do you have issues on both 2.4/5GHz networks and do they have separate SSID names?

    (You won't get replies if you YELL or state replies are "rubbish". You are replying to a 2 year old thread and fixes posted there may not apply to your current version of Windows and the current driver).
