Surface Pro 3 Slow WiFi - 72Mbps Max (driver)

So I got my sp3 yesterday and it was blazing fast on wifi. I did all the new updates and after doing so every web page was loading slow or timing out.

I did some searching and there a bunch of people with the exact same problem "Other forum"

I cant use my 5ghz network which is my wireless ac. I have a netgear nighthawk and the only way i can use this sp3 is by using the 2.6ghz now.

Please fix this. I'm shaking my head that first update screwed something up.... i already went through nightmares with my sp2 so this isnt a good start :(

So I re-installed September Marvell drivers cause I couldn't take it anymore. My download speed from local server jumped from 2.5Mbs to 19Mbs. I tested downloading a 6Gb file. It was consistent 18.8 rate. Substantial difference. Can be better though...

I have the same problem on 802.11n networks.  Speeds are woefully slow and sometime wireless drops off conpletely and the SP3 doesn't "see" any network adapters on board necessitating a re-boot.

Another problem, sometimes it doesn't wake up from hibernate after sitting overnight and other times it wont wake up from sleep or atleast the screen doesn't come back.

After I completed the mentioned steps I could see (in Device Manager) that the three items I had previously uninstalled were back. The O/S used the local version of those drivers to install them.

As for Windows Updates, I didn't see anything right away. If you have it check for new updates you will likely see the important update from 6/19 reappear for installation. Again, don't install this. If you do you will be right back where you started.

I have an Apple Airport Extreme 802.11ac wireless router at home and am only connecting at a max of speed of 72Mbps (usually closer to 11Mbps if I'm more than 20 feet away from the WAP). I have two other 802.11ac laptops at home (Samsung AB9+ and rMBP) and my two other computers are connecting up at 800Mbps+ and pulling down the same on Internet speed tests; yes, I have real GigE connectivity. Is anyone else having these problems?

I have read at least one more user reporting the same issue with the AC connection and it seems that everything started after the  firmware update.
