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

Hi

Small update to this issue. Picking up on what someone else said in an earlier reply about is there a certain set of models that were shipped with bad network cards.

The serial number of my Surface starts with 07 and my wifes with 04 - this is a bit of a surprise as we bought them from the same supplier and received them in the same delivery.

Any thoughts on if earlier models had defective wireless cards and how I could arrange to have this fixed/exchanged?

Thanks

Justyn

I wonder if I could trouble you all for some assistance here?

My wife and I purchased 'identical' SP3's - i7/8GB/512GB, they have both updated to the latest versions of Windows 10 and applied all the patches.

We are in the UK and have BT broadband. Mine SP3 connects to our BT Hub's 5ghz network perfectly and gives 74mbps down and 18mbps UP, but (and here's the kicker) my wife's find and connects to the 5ghz network but can barely connect to the internet.

Both work perfectly (but slower) on the 2.4ghz network.

All drivers at the same level.

Please does anyone have any advice as my wife now wants to return her SP3...?
