r66u and 802.11 ac

[Revelstone77]

I've got a brand new N66u with 376.2524 firmware and an edimax ac-1200 adaptor and can only connect to the router at 144m. what am I missing?

An 802.11ac router such as ASUS RT-AC66U

A router with AC abilities?

N66U is only a 900 class N router.

N66U is only a 900 class N router.

That's exactly what's missing. Buying an AC1200 USB adapter won't help if the router is only N. Achieving 300 Mbps requires 40 MHz bandwidth.

AC1200 should be able to connect at 450 Mb/s. As said check channel regulations and make sure 40MHz channel width is selected.

For completeness:
The RT-N66U is a 802.11n router, in theory it can reach 450 Mbps on 2.4 GHz and 450 Mbps at 5 GHz.
To my knowledge there are no adapters that are capable to use both bands in parallel to reach the sum of 900 Mbps, all or most adapters use one frequency band at a time.
The 450 Mbps is the result of three streams of 150 Mbps each.
The 450 Mbps again, is theorethically.
On 2.4 GHz you usually suffer a lot of neighbor interference, resulting in the router to scale itself down to a bandwidht of 20 MHz and limit the throughput to less then half of 450 Mbps. The generic advise is to set your router fixed to 20 MHz on 2.4 GHz to avoid the router to switch back and forward and to limit disturbance to your neighbors.
The range of 5 GHz is usually limited to one room, if you go further the throughput will be scaled down due to signal degradation.

The 802.11ac adapter will not be able to reach its full capacity, it will scale it self down to the 802.11n limits of the router.
The 802.11ac standard is defined, but the routers manufacturers work hard to release products that step by step get closer to the full features of the 802.11ac specification.

Sigh...

I had both routers saved in my cart and pushed the button on the wrong one. I'm such an idiot. Thanks to all for responding and not being too brutal. I did learn some thing from the responses, so it is a good day. It's hell getting old!

Thanks again.
