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

Hello SMartz1914,

Thank you for reaching out to the Surface community. You mentioned that since you had upgraded your Surface Pro 3 to Windows 10 your pages load slowly and the device itself is sluggish.

We would like to know a few things, have you restarted the Surface? Have you tried different web browsers? Could you please try to connect to another network to very if you are experiencing the same thing?

Please let us know how it goes.

Kind regards,

Scenario 1: SP3 & Win 10 Wi-Fi speed against two routers typically 2-10 Mbps. Tested tens of times.

Scenario 2: Everything else the same but instead of using Sp3's internal adapter Marvell driver version 15.68.3091.193, I use external ZyXEL NWD6605 USB Wifi adapter in SP3, speed is 25-45. Tested tens of times.

Also the other computers in the same location attain the higher wireless speed around 25-45 Mbps through these same two routers. Only SP3 is dragging its feet. Tested tens of times.

This shows that SP3's own Wi-Fi adapter is to blame, so questioning about routers and net subscription's max speeds or something else in the communication chain, which questions try to lead users' attention away from SP3's obvious inferiority is unethical whitewashing.

Hoping for an answer, not an unending thread of irrelevant questions. Even the honest "I don't know" would be a better answer.
