Well I downloaded manually a couple of days ago but haven't installed it waiting for it to appear on my UPDATE...got impatient and installed the Wireless driver....for me it was horrible...couldn't connect to anything...and noted that the driver version number is lower than the one I had installed. The July driver was 14.69....the one that I had from June was 15.68.3040.775. So I rolled back and now I get limited on 5ghz ...so I went to 2.4 ghz
You must have done something wrong, the wireless driver in that package is "DriverVer=06/03/2014,15.68.3042.79". At least for the "Surface Pro 3 - July 2014.zip" file... did you download the wrong one perhaps?

Use that guide to install your drivers/firmware.
Couple notes on the above guide;
-> 1. Execution policy for powershell scripts needs to be changed to Unrestricted for this to run.
-> 2. If you see Access is Denied messages it is because you didn't run as administrator.
-> 3. Not all drivers will install in that package so don't freak out if you see that occur.
-> 4. If you see a pause during the script execution, try and press enter.
-> 5. Once you run through this, a reboot is required although not prompted. When you reboot you will get the traditional a system update is being applied message. When I did this I heard my fan kick up speed. After reboot, I checked some of my drivers firmware and the wireless as an example has a date of 6/3 which is the official latest now.
All that said, I'm seeing an improvement on stability of the connections with both Bluetooth and Wireless N as to similar to what I had on my Surface Pro 1st Generation.
