Surface Pro 3 - Windows 10 - WiFi (slow or limited connectivity )

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

    Yep. I finally took Barb's (and Jo's) advice and bought a USB wifi adapter. What an amazing difference!   The one I bought, same one as Jo, was $13 on Amazon. The many hours and days I have spent with Surface basic and advanced tech support trying to fix this could have been avoided if had just taken Barb's advice long ago :/   Well, it seems "fixed" as I have not had to reboot my router in more than 24 hrs. Woohoo! 

    As for a class action lawsuit, the wireless driver in the SP3 is obviously defective and Microsoft knows it. Unfortunately, this Study Shows Consumer Class-Action Lawyers Earn Millions, Clients Little. So if the class got certified and went forward and was successful, we SP owners mightget a small check or a coupon. And that could be put towards the expense of a USB wifi adapter (for those who did not already buy one)!  Then again, in the years it would likely take to settle, the SP3 itself would be obsolete. So I'm out. I'm not interested in helping class action lawyers earn millions. Sorry.

    BTW, here is an interesting article from nearly 14 years ago about holding Microsoft liable for defects. It mirrors the same frustrations people are sharing about this. The comments get pretty ugly, but the arguments raised are pretty interesting.  http://www.geek.com/news/microsoft-to-be-held-liable-for-software-defects-549284/  

    I can' really figure out if you are trying to discourage people from sueing Microsoft or not but it sure sounds like that.

    Bottomline, when I bought a Surface Pro 3 machine, I did not sign up for non-working wifi, so I have not received what I paid for = Microsoft misleading consumers.
