Can't seem to sustain more than 54mbps wireless w/ R7000

[hungarianhc]

Having the weirdest issue. I had the R7000 set up w/ the default firmware, and my macbooks couldn't connect at a rate above 54mbps. I thought it might have to do with the firmware so I flashed DD-WRT. Same issue... Interestingly enough, in DD-WRT, if I start browsing the wireless settings, the highest "transmission fixed rate" it will let me set is 54mbps. Does anyone know what setting might be messed up here?

Is the client device capable of more than 54Mbps given its specs and signal strength (inbound AND outbound)?

using WPA 2 AES and WMM on ?

Jerry, this was indeed the issue. I did some research, and it turns out that TKIP, which is for whatever reason the default with DD-WRT, limits clients to 54mbps. I fixed... Changed to AES, and WMM is on. Now I can only connect at 104mbps with my wife's MacBook Air. On the other hand, she can connect at 867mbps to the AC68U. I'm thinking there must be some other configuration issue.

IIRC, TKIP implies use of WEP and, I don't know why, WiFi seems to fall back to 54Mbps in WEP mode.

802.11 specs that hi throughput rates (anything above 54Mbps) require WMM and WPA2/AES (or no encryption)
