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

    Hi Barb,

    Thanks for your patient. I talked to a Microsoft support technician. After 1 hour repeat what you suggested to do, he did not fix the problem and said he will report it to his company. What a JOKE.

    I just found out there is another issue with the microphone. They all behave the same. They will not be waked up or turned on after sleep or restart.

    I have tips, you may give them to other people who are suffering the annoying problems from well-expected windows 10. It is turn off WIFI, then turn it on. For microphone, redo microphone set up, whenever Cortana does not respond to you call.

    Thanks again for your support, despite Microsoft does not pay you. You are better than the Microsoft technician I spent 1 hour with.

    Hi Barb - I have issue in the middle of a session. At this point I pretty much will reboot the machine, see it connect for several second and then go into limited connectivity mode.  Same issue regardless of 2.4 or 5 connection.  The machine is sitting at home at this point so it is only trying to connect to a single network.

    Thanks.
