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

Which Comcast gateway exactly? Model? Îf you didn't change some settings you have double NAT and other issues. Did you update the r7000 firmware? Did your SP3 come with Windows 8.1 or 10 and have you manually checked and downloaded all available updates?

I just purchased a new Surface Pro 3 and I've already returned the first due to the Wi-Fi issues. This new one has the exact same issue so I've been reading the forums trying to find a fix.

I just hooked up a Netgear Nighthawk R7000 to take over for my Comcast gateway as I thought that was the issue. The Netgear VASTLY improved the 2.4 connection giving me around 80mbs instead of the 6ish I was getting with the Comcast gateway. The 5ghz is only giving me 10mbs however. This is better than the .05 I was getting before but not nearly where it should be.

I've tested it with the SP3 set to only connect to 5ghz and I'm on the latest drivers. No luck on getting the 105mbs I'm paying Comcast for. All of my other devices are getting 110+ speed on the 5ghz connection.

Any advice?
