802.11N capability

Does this mean my RT-N16 does NOT support 802.11N?

The highest Supported Rate is 54 Mbps.

Although a TP-LINK USB stick can connect at 72.2 Mbps.

Did you tried 40 mhz?

You have a good point szepe.viktor. I see the same on my RT-N66U and indeed my wifi speed seems to be limited at about 54Mb/s, because I can't transfer beyond 6-7 MB/s with my 450Mbps Intel 6300 wifi card.

Mode	: AP Only

I have enabled 40MHz. And I'm not in AP Only setup, even though it says so.
As you say, clients show a higher link speed than 54Mb/s, but actual speed appears to be capped around that.

Those rates are legacy values, and have nothing to do with 802.11n or ac link rates.

Thanks, Merlin. Any clue why my Intel 6300 card can't go beyond 6-7 MB/s?
No interference from neighbours, tried two different cards, tested not only with the router's usb hdd but also with a gigabit ethernet desktop, with and without channel bonding.

What's your link rate? How are you testing speed to obtain these numbers?

The link rate is 217 or 173 Mbps. I'm transferring a large mp4 between my wireless notebook and a gigabit ethernet desktop. I've tried both uploading to the desktop and downloading from the desktop.
The desktop manages about 12MB/s when transferring to/from the router's usb hdd.

Edit: here's what I see in inSSIDer.

At the end i had to buy a new router with 5ghz support.

2,4ghz frequency is very crowded in my house with bluetooth devices and various gadget on 2,4ghz.

Also too much devices in my neighbourhood in 2,4 ghz.

A 170 Mbps link would cap at about 8 MB/s on average, so you aren't that far from the limit of what you can get out of that link rate on the crowded 2.4 GHz band.
