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

Correct. But Microsoft has not been quick in addressing the issues with the

Marvell driver and certain routers. If you don't post the

manufacturer/model/firmware version, it will never get addressed. And sadly,

even though every other device you own has no problems, your issue may never be

addressed.

Not sure why you waited nearly a year to post - but info on your router is

needed.

>> I have supported Microsoft since DOS 3, and my SP3 is 1 year old and about out of warranty, this is not a router issue.

I have supported Microsoft since DOS 3, and my SP3 is 1 year old and about out of warranty, this is not a router issue. turning the SP3 Bluetooth off and I gain 3.0 mbps on my Microsoft Speed Test. I hope Microsoft extends their warranty period until this is fixed. My router is loved by our TWC Broadband, DTV Genie, Samsung TV and 2 cell phones, 2 readers, 1 HP DVD 6, and 2 Lenovo 8.1 pc/tablets that smoke compared to my SP3. It would be cheaper to pitch this SP3, buy a new Yoga pro 3, and figure this is another Microsoft Ultima TV project unsupported.
