I have a Draytek 2860ac Router which operating at 5Ghz with 802.11ac. I have tried to connect to it with several 11ac Adapters on WIndows 7 but I only seem to get a speed of 86Mbps. (see Attachment)
I think the problem may be related to the fact that the radio type is detected a 11n rather than 11ac but I am certain that the Router is configured as 11ac/5Ghz as I have checked it with Draytek support.
What could the problem be?
