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

Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897

Find the item labeled “TXAMSDU”. Double tap and modify the value from 0 to 1
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

It appears that the new firmware update dated 9/29/15 has solved this problem for me. Turned location services back on and my network speed is stable and what I would expect.

Yes, there are people having this issue and Microsoft has not yet commented on

if they know why or when there will be a fix.

might help - see my comments about finding the older driver and installing it.

I wish I had better news, but I don't..

Edit: Firmware for the SP3 was released today 9/29. It includes a new Marvell wireless driver. Check manually for updates and install. Some people report that it fixed their issues. For me, it created issues as I was not having any with the .193 driver. I had to manually reinstall the older .193 driver to regain stable connectivity.
