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

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?

    Hello all

    Thank you for continuing to provide valued feedback and details.  We are tracking several active posts that deal with WiFi performance. We are working on an additional update to the WiFi component in the September time frame.

    Please continue sharing - your efforts are appreciated.

    Best regards

    Quick update from me. Right after I installed new update, LAN speed went up to 300Mb, and went down back to 72Mb after a reboot. Tried reinstalling driver with no results. Iam running on N.

    Thanks John, glad someone is listening.  The latest update from yesterday seems to fix some people but it didn't help me.  My wifi connection speed to my Dlink DIR-868L is at 72mbps.  Connection to a Dlink DIR-655 is at 65mbps.  I don't have connection problems (maybe because I'm sitting next to the router) but I should be getting much faster speeds with these N and AC routers.  I'm ok with those speeds for now.  Looking forward to the next update.

    Hello, just wondering, how are you testing the transfer speed? via file explorer between SP3 and a server on the other end in the LAN?  Are you able to test with another computer under the same LAN setup that connects to the same AC router via wireless and then do the same transfer speed test and see the 200+ Mbps speed?

    Thank You

    Hello, after a few hours with the updates I also thought it was fixed but the SP3 started to lose the Wi-Fi connection while on stand by, I would no longer hear the "Ding" of new email, when I tap on the power button I would see no bars for a few seconds and then it would get the connection again.  Eventually it totally lost the connection which even turning off WiFi and turning it back on did not help.  I had to reboot.

    So I went back on the router and set the 5 GHz to the higher channel 36 and it has been stable since then again.  

    Overall the updates did help maintain a stable connection for a much longer period and I did not see the "Limited" connection icon nor I saw the speed degradation issue anymore.  Those are good things.

    One thing that troubled me is that the battery life took a hit with the latest updates for me.  I will test more this week and report.

    After testing today with the 5 GHz router in the higher channel and verifying that it works, I am going back to my USB Wi-Fi adapter again until you guys release the next update on September.  I see it going in the right direction but it is not working like a *premium* device should be working after so many patches and with a company with so many resources it should be quite easy to test all these issues in house before releasing new updates.   IMHO

    Thank You
