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'm wondering if the symptom may be a sign that Homegroup connectivity ICS is being used?  FWIW one of the strange symptoms I had last night (part of the hang scenario I mentioned) is that when I asked my Surface RT to troubleshoot the Homegroup, everything on the Surface Pro sprang temporarily back to life.  Another reason why I'm not ready to suspect such problem symptoms are due simply to networking.  There is a whole lot more involved in this convoluted stuff and the troubleshooters are interfering (probably for "security" reasons) more than helping.  E.g. the fact that I was able to use my Surface RT to connect with the "hung" Surface Pro through the wireless connectivity (bridge not router--router is in the modem) puts the lie to the troubleshooter's hypothesis that all I needed to do to make everything work again was power off all my comm hardware for at least 10 seconds and then wait for it to become active again.  This is why we need some objective facts (not guesses, especially ones which ignore security considerations) to understand what is really going on.

    Hi Barb, here is my driver and router info:

    Router: I am using the router provided by Verizon (FIOS G1100) , I couldn't find the router firmware version.

    OS: Using Windows 10 with SP3, Marvel driver version is 15.68.3091.193.

    The VZ router is configured to use the same SSID for 2.4 GHZ and 5 GHZ.

    I tried using a NetGear WNDR3700 router that had separate SSIDs for the 2.4 and 5 GHZ channels and had the same slowness and instability issues when using the 5 GHZ channel.

    The only workaround I've found so far is to force 2.4 GHZ at the Marvel adapter driver settings, it results in a stable connection (it still fails every once in a while when recovering from sleep and I have to run network troubleshooting, reboot or turn airplane mode off and on to recover) but has significantly reduced transfer speeds compared to all the other machines in the house that are connected to the same router (2 Lenovo, 1 ASUS and 3 phones).

    I hope it helps.

    Gabo
