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

Turn off location services and see if that helps. I'm having the same problem, but read somewhere about turning off location services and it indeed fixed my slow wifi issues.

Go to settings/privacy/location and turn location off. See if that helps. Definitely not a router issue for me.

I have been having troubles with slow WIFI since I bought my Surface pro 3 five months ago. I have a Technicolor router and a TrendNet extender in my home. The extender gives my laptop approximately 15-20 mb/s. in my office. Today my Surface pro 3 gave 1-2 mb/s in the same location. I have been looking for solutions to the bad wifi adapter in Surface since I got it. It cost me a lot of time. Now that I see this simple proposal for solution to undo "location" I am astonished to see that net speed is increased from 1,7 to 18,0 mb/s.! How is it possible that Microsoft has created this problem for thousands of Surface users if this is the real solution? I feel we diserve an explanation!

for diagnostics, can you unplug the extender and turn location services on? this

is a diagnostic. I can send info in to a contact on the Supportability team, but

I need this data.
