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

  1. Navigate to the following path:

 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\mrvlpcie8897

  1. Find the item labeled “TXAMSDU”. Double tap and modify the value from 0 to 1
  2. 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

    Sorry - I was using tech jargon from the ISP.  Here's how their specialists in Comcast's Advanced Wireless Tech Support department explained it to me... 

    Type 1 routers are single band units designed to support speeds up around 50MBs.  They can go higher (up into the upper 70's MBs if the service speed is there), but will get burned out within a few months pushing those speeds.  I had a Type 1 (due to a cable company mistake) for a while last year.  I have 170+ MBs service and I burned that thing out in less than six months.

    Type 3 routers are dual band units (2.4 and 5.0) and can run speeds up into the 100's of MBs (at least in the 5.0 setting).  Per the advanced tech support guys from Comcast, anyone with internet speeds well over 100MBs should be running a Type 3 (but could get away with a Type 2 with slightly slower throughput and a low risk of burn out).  With my service in the 170's MBs, I needed to use a Type 3 to get the speed I was paying for each month.  I'm currently running a Cisco DPC-3941.  We looked at a DPC 3939, but it wouldn't handle the throughput.

    I don't understand your reference to type 1,2 and 3 routers. This isn't a nomenclature I've seen before. What do you mean exactly? For reference, I personally don't have speed issues on Netgear 7000, 7500, or 8000 routers. But it IS a driver issue of some kind.

    If you can find the older driver (Microsoft won't post it, you will have to find it elsewhere), make sure it is from a reliable source, then you will have to extract it from a zip file and use the browse, let me choose have disk option in device manager to install it. It isn't legal to redistribute Microsoft software, so third party sites should not be hosting downloads..
