Have the ASUS RT-AC66U and everytime trying to connect to the 5G AC band it will connect for 1 second and drop all signal. Updated drivers from website, still same issue. Going to RMA this and go with another AC adapter.

Other Thoughts:

This did connect to 5G and 2.4G using N standard since I also have the Linksys EA4500-NP. But I brought this so I can upgrade my network to AC standard.
