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

Yes , 5 GHz has its own name.

And I do not think changing the router settings to try to make a single device, in this case be SP3, is right. Every other device connected to the router works 100% fine and never drops the connection.

The SP3 drivers are faulty and Microsoft needs to solve the issue.

Imho

I agree that MS needs to solve the issue....no argument with that.

I didn't make a single 5ghz connection with my Apple Airport Extreme AC router.  It's a dual-band router.  It's now broadcasting two SSID's.  The 2.4ghz SSID is named "myrouter"; the 5ghz SSID is named "myrouter 5ghz".  Both are selectable now when searching for my home network signals.  My older wireless gear connects great to the 2.4ghz SSID, and my SP3 is connecting great with the 5ghz SSID. 

Are there any other 5ghz signals being broadcasted by your neighbors?  Perhaps they're on a channel conflicting with yours?  Of course, I still agree with your statement that MS should solve the overall issue.  However, in the mean time, I'll make due connecting to my 5ghz SSID and leave my 2.4ghz SSID to my other wifi connected devices.

No luck for me on the 5ghz ssid .  it is fast but drops the connection constantly. Have to reboot at least twice per day to fix "limited connection" issue when connected on the 5 GHz.

I had a similar issue with a Linksys router I had a couple years ago (before the surface pro).  I found that setting the router to a specific channel (instead of automatic) fixed the issue.  It appeared that my router  signal was fighting my neighbors' routers.  I downloaded an app for my android phone that was a wifi analyzer and it showed what wifi channels were being used in my area.  I then went into my router settings and set the wifi channel to one that wasn't being used.  I no longer lost signal from the router.

Yep....exactly what you've shown in the image.  I clicked the checkbox...it said it made a 5ghz SSID....I hit the "Update" button....the router saved the settings....I disconnected from the 2.4ghz SSID and logged in to the 5ghz SSID.  Good to go.
