My router actually can't keep up Even with deep packet inspection and all the security features turned off I can't crack 1700. If I connect directly to their provided router I get the full 2K. (I have a first version unifi dream machine pro, the SE supposedly handles it just fine).
He just said if he takes the router out of the picture he gets the full 2Mbps, that's a pretty solid data point.
I believe it. The Unifi routers aren't the most powerful. And they've had their share of bugs. I had a couple firmware updates where my USGs couldn't even keep up with the 300Mbps I had at the time.
