I'm having a weird issue. I just got the new macbook pro with 802.11ac 1300. It connects at full 1300 at 10ft distance straight line of sight to my AC68U. However, I can never break 30MB/s over the wifi while I should be getting upwards of 60+MB/s over the ac. My storage server has well over 200MB/s transfer speeds with link aggregation and large RAID 5 array. The new OS X Mavericks has SMB 2.0 and supposedly has the SMB speeds fixed according to tests with other APs. I still can't figure out if the problem is in my AC68U or my laptop since I only have ac adapters in my macbooks. Can anyone test transfer speeds with the AC68U and see if he can achieve more than 30MB/s over 1300 ac?
