TP-Link TL-WDR3600 not broadcasting N signal

I just got a TP-Link TL-WDR3600 router. After flashing it to the latest stock firmware and setting it as a AP (disabling DHCP) behind an ATT 2wire modem/router (disabling the wirelss on the 2wire)

I've set the TP-Link TL-WDR3600 to only broadcast an n signal in the 2.4Ghz band and not in mix mode. On my laptop, it shows that the radio signal is g and I'm only getting g speed (~5MB/sec) for file transfers.

I've tried rebooting the modem and also resetting it.

What am I doing wrong or configuring incorrectly to not get the N signal?

Thanks in advance.

 

If you're getting 5MB/s of actual file transfers it means you are running 802.11n regardless of what your laptop is showing.
802.11g can't go above 2.5MB/s.

Just to make sure- check that you're using WPA2 Personal + AES as security.

 

Are you running it in 20 MHz (single channel) or 40 MHz (dual channel) mode?

 

@downloads,

I was hoping 802.11n would be somewhat faster in the 10MB/sec range. Then again, there may just be more interference where I am living. I know that I can get 40-60MB/sec when I hard wire my laptop to the Gigabit ethernet. I may have to hardwire it in the near future.

@ WackyT,
I have it set at 40MHz.
I have

 

10MB/s is possible on 2.4GHz if you're lucky, have a good router and a good wireless card, no interference and so on.
Realistically 5/7MB/s is more like it.

Anyway- anything above 2.5MB/s has to be "n" so you're running it already.

 

Ntheo, what wireless card are you running on your laptop? What does your wireless environment look like in a program like inSSIDer ( http://www.metageek.net/products/inssider/)?
