I've only just got the Surface 3 this afternoon. Very nice too but I was surprised when I checked the wireless speeds that they're way down on what I expected. I have Telstra cable and consistently get 110 - 115 Mbps on Wireless AC on the SP3 and about 90Mbps on wireless N. I'm getting no more than 60 Mbps on either and sometimes down to 17 Mbps on AC. It is all over the place but the computer doesn't seem to be particularly busy. I was thinking it is drivers but I was watching the CPU activity and I think it keeps the CPU very busy averaging about 70% on the Surface 3 and about half that on the i7 Surface Pro 3. It may be that the internet speed on the Surface 3 is limited by the CPU if you have very fast internet speeds.
