Jbckhoo, I'm replying here copying a reply I made to Zack_T from Microsoft on the other "Surface Pro 3 Slow Wifi" thread where Zach_T asked for feedback.
The October 28 firmware update has done nothing whatsoever to fix the wifi performance on my Surface Pro 3. It takes the Surface wifi adapter 37 minutes 16 seconds to transfer a 1GB folder (two files) that a cheap Patriot wifi dongle transfers in about 1 minute. The Surface remains about 35 times slower than the Patriot dongle and pushing 20 times slower than an old Dell laptop. The router is a Netgear N300 WNR3500Lv2 about five months old.
This is disappointing, as I've been looking forward to this new firmware since it was first promised several weeks ago.
I note, though. that the Surface wifi adapter transfers the same folder from the Surface to my desktop in 6 minutes 52 seconds. So it is faster (but still slow) sending data than it is receiving data.
