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

Ive been having issues as well. The best thing to do is contact your local MS store and inform them of the issue, and request a SP4 replacement. MS can't seem to fix problems with SP3 wifi, and I wouldnt expect a solution anytime soon. Sorry man.

I definitely think you are right.

um... Its actually kinda **** cause

Microsoft center in Korea(where I live) is so fool.. Seriously.. I don't know about States or other countries but here, it truly sucks... Every time I call Microsoft, an agent who can't speak Korean comfortably receives the call. There was a rumor in Korea that call agents responsible for SP3 are Chinese-Korean, and I assume that it's true. They don't know anything about technical problems and what they do is just make people wait. I guess the reason for this is the benefit from low wages. Microsoft can't simply do that.

I had a kickstand and overheating problem which made me to exchange a product, and it took me more than 5 weeks! yeah, 5 weeks. After I changed though, overheating wouldn't simply be fixed. Plus, it's the internet now. After upgrading to Win10, come on.

I guess the local MS store wouldn't help. Well there is no MS store in Korea? Maybe I should contact to the headquarters about this thing. Just wondering Koreans who aren't so comfortable with English keep up with the problem..
