Did you find out how to fix the problem?
I got excactly the same "symptoms" - it drives me crazy since it works with other equipmtent.
I am having the same problem with my setup. I get <80kBps (that's only 640kbps) file transfer operations between Win7 PCs on my LAN (server wired to switch connected to RT-AC66U and client wired to switch connected to EA-66N). I have steady blue LEDs on the 66N which indicate a strong signal and I am on my 5GHz SSID.
Another funny issue is that my AC66U reports the 66N client has an Rx/Tx rate of 6/450 in Mbps. I have no idea why the receive rate is reported so low for the 66N when my other 5GHz N devices do not have this problem. I do have a Realtek onboard NIC in both machines. I updated the driver to v7.069 for Win7 from 3/26/2013 as the Asus support site suggested, but that did not seem to work (then again I didn't reboot after driver install but device manager did show the new driver). I am wondering if I need to do the same on the server driver that connects directly to the AC66U. I am also wondering if there is some driver setting in the Advanced tab that I need to modify.
As previously suggested in this thread, I also disabled QoS on my AC66U which also did not resolve the LAN performance issue. Another thing to note, I have a WD TV Live also connected to the switch that uses the 66N to bridge back to the rest of my LAN. The WD TV Live does not seem to have any performance issues as I am able to stream HD video from the same server where my Win7 client has the performance issue. There is no way I could stream HD video over a <640kbps connection.
I opened a ticket with Asus support. Hopefully they can help but I have not had much luck with manufacturer support teams in the past on these kinds of strange issues.
