Connection Speed issues with RT-N66u

[bluelightning]

Hello ,
I just setup my Rt-N66u router yesterday and I am having connection speed issues with. I am getting about 10-15 db stronger signal than my existing routers when measured with inSSID in both bands ( compared to a belkin dual band router and a D-link 655 router), however in the wireless network connection status it is only indicating a speed of 54Mbps, compared to the 130/150 Mbs with the previous routers. I have examined this on two laptops with similar behavior. I am using a bigfoot 1102 ( 2 antennae) wifi card in one laptop and a generic (I think Realtek) 2 antenna card on the other. Both of which laptops behave just fine with the other two routers.

Thinking that this might be just an issue with the status I connected a 3 TB external Hard drive via USB and tried transferring some large files wirelessly and the download rates are similarly slow . I am getting 20Mbps transferring files wirelessly @5 GHz. Connecting via gigabit ethernet I get about 40Mbps. (5 MB/s as displayed by Windows)

Is there something I am missing or do I just have a defective unit that I need to return ?

I have the latest firmware .108 which I flashed , then reset the configuration, rebooted, reconfigured etc.

Bandwidth 20/40 Mhz set
Tried with Channel , fixed in a few positions as well as auto.

Thanks for any help or suggestions

If you set mixed mode, or did not set WPA2 AES on security set up. it may slow down. Just try -N mode only with WPA2 AES set up. As well check if you have newer driver for the WiFi cards.

Thanks for your reply. I am currently set to N only with security settings of WPA2 AES-TKIP. The bigfoot 1102 installed in one laptop is pretty recent. I will try to see if there is a newer driver available though.

N spec requires you to use WPA2+AES to get most thoughput, anything else it will drop you to 54mbps which is expected. In most env 20MHz channel works best for a 2 radio system rather than a channel bonded 40MHz.
Thanks

That fixed it.

Thanks to both of you. The default setting has AES-TKIP and wireless mode set to Auto. Changing to WPA2 & AES did fix this problem. For a while I was wondering if I had a defective router with only 1 antenna working. Forgive my ignorance on this.

Now I need to figure out why I am getting slow transfer rates with my 3 TB external Hard drive connected via USB. Currently I am getting about 5 MB/s read and something like 760 kB/s write speeds. This is a relatively new HD with USB 3.0. Any suggestions ?
