I just purchased a Surface Pro 3. (latest wireless Maravell driver)
I have a NetGear Nighthawk R8000 AC router. (latest firmware version)
On the Surface pro I have ridiculously slow internet on the 5g and 5g2 bands. By slow I mean below 5 mbps. On the 2 ghz band I get around 50 mbps . I have other devices in the household which use the 5g and 5g2 bands with no issues (~90 mbps).
I tried rolling back to the previous version (15.68.3073.151) for the Marvell Avastar wireless. This was worse, limited connectivity on all bands). Even if this worked I would need to turn off Windows updates or it would probably be replaced.
I hate buying a new product and have to monkey around to get (what is advertised as) AC wireless speeds, especially at the price of the SP3. Any last options I can try before I return the SP3?
