Microsoft Announces Upcoming Updates to Surface Pro 3


Some good news, Microsoft has announced upcoming updates to the Surface Pro 3 on TechNet. In particular, there are some WiFi updates that hopefully will fix some of the horrific issues that have plagued some customers since launch.




Note in particular:

Wireless Network Controller and Bluetooth driver update (v15.68.3066.135)

  • Enables better throughput after waking from sleep and connecting to an 802.11AC network.
  • Ensures Infra scan list is not empty while connected to a wireless display adapter.
  • Resolves an issue connecting to Cisco 1242 access points.
  • Ensures device reconnects properly to a hidden SSID using a 5Ghz DFS channel after waking from sleep.
  • Adds customer-requested functionality to prefer 5Ghz connections when both a 2.4ghz and 5ghz connection are present with the same SSID.

Too bad Microsoft didn’t have the common sense to post this information in the Answers Community Forums where users are begging for relief.

Get Glasses for Surface Pro 3 for Clear Documents Take 2


A while back I wrote about experiments to try to take usable document photos with the Surface Pro 3 camera.


I’ve got a somewhat better solution now, thanks to Hydrotac +3.00 diopter stick on lenses from Amazon (I had a credit there burning a hole in my pocket) and some non abrasive clear sticky tape.

Here’s my “modded” Surface Pro 3:

This low tech solution is usable. I still wish Microsoft would have used a variable focus camera so that clear and crisp document capture was a usable scenario.

Real World Data Points on Slow WiFi on Surface Pro 3 using 2.4 GHz


Microsoft Surface customers have been complaining about slow WiFi speeds using their Surface Pro 3’s in Microsoft Communities and elsewhere. I wanted to clearly frame this issue for anyone that might be interested. (Microsoft are you listening/reading?)


As I’ve stated before, the very fast 802.11ac speeds only are achieved on a 5GHz SSID. Folks with single band 802.11 (2.4 GHz) routers are not going to achieve the fast speeds that 802.11ac offers. Given that nearly all of the public WiFi access points are 2.4GHz only (Starbucks, McDonald’s, etc.) and that the Surface Pro 3 has severe performance issues with the Marvell wireless radio when using the 2.4 GHz band, it’s easy to see why there are so many unhappy campers. I’ve written about tweaks that folks can use at home, but these provide only incremental speed boosts when attached to a 2.4 GHz network using the Surface Pro 3. The speeds obtained are dreadful when compared to just about any other wireless adapter on any other similarly equipped computer and far less than can be obtained when using a USB wireless 802.11ac adapter on the SP3, and using the 2.4 GHz band (as you will see).


All of my testing was done from the same location in my home, in my living room on the first floor with the Netgear R7000 router on the 3rd floor. I tested with and my ISP provisioned speed is 105/10.


Testing with my ASUS ROG “desktop replacement” which has a Broadcom 802.11ac built in adapter:


As you can see, my speed exceeds my provisioned speed.

5 GHz 2.4 GHz
asus 5 ghz ausu 2.4


Testing with my Surface Pro 3:

Still getting great speeds on 5 GHz, but totally dismal speeds on 2.4 GHz.


5 GHz 2.4 GHz
sp3 5ghz sp3 2.4 ghz


Others report even less that the 12.49 speed I can achieve. It’s crazy bad.


Disabling the onboard WiFi in the Surface Pro 3 and using a Netgear AC600 802.11ac adapter:


While the SP3 has a USB 3.0 port, the wireless adapter, like almost all the other 802.11ac USB mini adapters available today, is still only USB 2.0. While USB 2.0 has a theoretical 60 Mb/s rating, most folks have found that it tops out at 40 Mb/s in the real world on all devices.

2.4 GHz
 netgear usb 2.4


So even with the restriction of USB 2.0 speeds, the difference between the Marvell wireless and the Netgear USB 802.11ac adapter performance is alarming.

It’s infuriating to customers that Microsoft hasn’t addressed the issue or even commented specifically about it. Is 12.49 Mb/s fast enough to check email? Sure, if you don’t have lots of attachments. But is it what people expect of a $1400 device? No way.

A $40 Fix for Surface Pro 3 Slow WiFi


I recently wrote about the wireless speed issues with the Surface Pro 3 and several ways to trouble shoot, including making configuration changes, buying a new router, etc.

Without knowing when or if the Surface team will fix this, there is another option that you might want to consider. Purchase a third party USB 802.11ac wireless adapter. Nearly all the USB 802.11ac wireless adapters use the Realtek chip and examination of the base Realtek driver shows support for every manufacturer I could think of. I picked the Netgear version, available at Amazon for $40. There are other brands at other prices available on Amazon and elsewhere, but I can only write about what I personally used and that experience.


netgear usb ac

I took my Surface Pro 3 on a trip around town to places where the WiFi performance was unsatisfactory. I had disabled the onboard Marvell wireless in device manager and was using the Netgear AC600 specifically with the “standalone beta driver” from Netgear’s support site.

I did not experience the issues that I previously had with the onboard Marvell.

Yes, it is $40 folks shouldn’t need to spend, but given the current state of affairs with no sign of relief in sight from Microsoft, I’d rather travel around with the external USB adapter and know that I have options.

Let me know on Twitter @barbbowman if you’ve tried a different USB wireless adapter with your Surface Pro 3 with good results.

Logitech K810 Setpoint Incompatible with Surface Pro 3 after September Update


Logitech has a really nice backlit K810 Bluetooth keyboard that many folks had been using with their Surface Pro 3 tablets successfully and without problems. After the 9/9/2014 updates, reports started surfacing (pun intended) on the Communities Surface Forums and the third party forum at . A thread has been started on the Logitech Forums as well.

logitech K810


It turns out that the September Surface Pro 3 driver firmware/update for the Marvell WLAN/BT adapter now conflicts with the Logitech Setpoint control software for the K810 keyboard. The keyboard pairs, but immediately goes into a connect/reconnect loop and may display a driver error.

Work Around:

Users are confirming that uninstalling the Setpoint software (which again, worked prior to this update without issue) resolves the disconnect loop, but of course prevents setting up Function Keys permanently, etc.
