Offers users new 5th generation Wi-Fi (5G WiFi) with speeds up to 1.75Gbps
alongside ASUS PCE-AC66 and USB-AC53 802.11ac-capable client models

The ASUS RT-AC66U router integrates dual-band Gigabit wireless with fifth generation 802.11ac Wi-Fi technology, also known as 5G WiFi,
which enables speeds up to three times faster than existing 802.11n. As one of the first routers to achieve this, it tops Gigabit wireless
requirements with a combined 2.4GHz/5GHz bandwidth of 1.75Gbps. This massive data rate makes it an excellent high speed router for
demanding online applications, coupled with exclusive ASUS AiRadar signal amplification and shaping technology. Easy ASUSWRT setup,
multiple SSIDs, and IPv6 support further enhance networking, while strong USB-based capabilities turn the RT-AC66U into a 3G, FTP,
DLNA, and printer server for genuine multi-role functionality.

ASUS RT-AC66U Dual Band Router

Going beyond Gigabit Wi-Fi to triple wireless-N speeds

The RT-AC66U goes even further than the successful high speed RT-N66U dual-band router. Working in both 2.4GHz and 5GHz, it is one of
the world’s first dual-band wireless routers to support the advanced 802.11ac wireless protocol, enabling 5GHz operation at up to 1.3Gbps.
These new capabilities are made possible by the inclusion of Broadcom’s powerful 5G WiFi chips. As the 2.4GHz band can work at 450Mbps
on its own, the concurrent combined bandwidth of the RT-AC66U is 1.75Gbps. It uses sophisticated ASUS AiRadar technology to strengthen
signals to devices, amplifying transmission in directions to better overcome environmental obstructions and improve data rates. The inclusion
of 5G WiFi makes the RT-AC66U one of the most future-proof routers on the market, ready for the next generation of high speed networks.

Extensive feature list enhances networking experiences

The RT-AC66U maintains the tradition of networking excellence established by previous ASUS high speed routers. It allows for easy and fast
setup in just three steps with the ASUSWRT dashboard, and upholds strict QoS standards for the most reliable networking and download
multitasking available. With QoS, the RT-AC66U has better bandwidth optimization, and offers Download Master capabilities, which mean fast
background downloading even post-shutdown. Up to eight SSIDs are supported, so users can easily setup distinct networks with different
access privileges and levels of security without having to compromise passwords. The RT-AC66U supports the new IPv6 standard for better
packet transmission and addressing.

USB applications extend router versatility

With its twin USB ports, the RT-AC66U becomes a true multi-role device. Attaching a 3G dongle allows it to share 3G connections among
several users on different devices, while full DLNA compatibility affords smooth connectivity with also variety of entertainment platforms,
including game consoles, Blu-ray players, smart TVs, and set-top boxes. The RT-AC66U can also serve dedicated FTP server and printer
server, letting users share resources for greater productivity while reducing costs as there is no need to buy standalone server hardware.

Full 802.11ac product lineup

In addition to the RT-AC66U router, ASUS has also released the PCE-AC66 and USB-AC53 clients, both capable of 802.11ac speeds.
The dual-band PCE-AC66 offers a PCI Express client card for desktops, with 3 x 3 high-powered transmission. It can sustain 1.3Gbps
in 5GHz and up to 450Mbps in the 2.4GHz band. For easy USB upgrades to 802.11ac, the USB-AC53 compact dongle plugs into any
USB port, with 2 x 2 802.11ac. In 5GHz, the attachment can maintain 867Mbps, while in 2.4GHz it works at 300Mbps, achieving a
total throughput of around 1.3Gbps. The PCE-AC66 and USB-AC53 are enabled by Broadcom’s 5G WiFi chips, and demonstrate ASUS
technology leadership in bringing an 802.11ac ecosystem to consumers.

Great, thanks for the info ;)

If the only "improvement" of RT-AC66U is the AC radio and 128MB Flash RAM and the rest is the exactly the same as RT-N66U i don't think it's worth changing, i speak for myself... I don't need such speeds ratios and i don't have clients AC radios ;)

Im surprised:

RT-N66U rev 3.00 released, 2 months later RT-N66U new rev 3.20 released, less then a month later RT-AC66U released... I'm not sure if this will end soon ;)

it starts at € 300 .... :eek:

http://www.cyberport.de/?DEEP=5615-025&APID=14


let's hope it will drop the RT-N66U price a bit

edit: that should be a typo... the other ac -routers are starting at € 199

Too expensive in my opinion and i don't think it's a typo, either way 3rd party FW's could take some time to be released.

http://geizhals.at/192400415 => 240ˆ now

To good to be truth? I doubt RT-AC66U CPU changed.

According picture it's BCM SoC
Not the same as in RT-N66U, because there were one BCM4706 CPU and two BCM4331 radio chips on PCB.
No SD cardreader also :)

My question was:

Will be RT-AC66U use CPU BCM4706 (MIPS 600MHZ like RT-N66U) or BCM4707/4708/4709 (ARM 1GHZ)? I know its a BCM SoC, but which one? Is there a confirmation?

Asus RT-AC66U AC1750 WLAN Router ˆ 239,90 :confused:

Thanks, that means (in my opinion) it not worth the changing.

1. Probably will be a long wait until we see a Oleg FW for this model (RT-N66U a good example). I believe DD-WRT and Tomato being available a few days later after being selling on stores, but i would prefer Oleg so...
2. The only changes are:
- 4X more flash size (128MB) (for what?)
- Probably a 64KB NVRAM (oleg does not need this)
- AC radio, i would never need those bandwidths and if i would, i would need to pay alot €€€€€ for AC clients. (no thanks)
- Higher price. (no thanks)
- No MiniSD Card slot.

I prefer saving the money for the future BCM4709 router, not sure if Oleg will support it since it's a ARM chip, probably not. Maybe lly and themir0n can tell ;)

And these are the reasons i prefer our firmware here, on top of openwrt and stuff... No worries about what is packed in the Firmware and does it fit. You want 1 GB program-data? No problem my partition is 2 GB. ;)
Sure, flash-storage is faster than a hdd... but once a program is started, the messy stuff runs in RAM - there we need bigger chips - not more flash :mad:

With a BCM4706 (MIPS), TomatoUSB should only need drivers for the BCM4360 to get it working (or maybe some modifications to support 1300mbps).
With ARM architecture, it would probably be a ton of work to port it. And then you'd need to recompile the programs you want for ARM too (optware stuff).

Would be nice if it did happen though (but unlikely).

At a distance of 15 feet, the Asus registered the fastest Wi-Fi speed I've seen, scoring 339Mbps (or about 42MBps, close to the speed of a Gigabit Ethernet wired connection).

What a joke, it's not even half of the gigabit speed:rolleyes:
Maybe in the near future we'll have 10gbit wireless and we'll be able to reach 500Mbps;)

All three use the same Broadcom BCM4706 CPU. At 256 MB, the AC66U has double the memory of the other two routers,
but the same amount of flash. The same Broadcom BCM4331/BCM4360 radio SoCs are used in all three products.
But the ASUS is the only one of the three to use dual-band external antennas vs. six internal single-band. This means the
external circuitry connecting the radio SoCs to the antennas is different. It looks like the Skyworks 5 GHz amplifiers made it
into ASUS' design. The BCM4360 5 GHz radio is toward the top of the photo; the BCM4331 2.4 GHz radio is toward the bottom.

Removing the bottom plate revealed 128 MB of Samsung flash (K9F1G08U0D) and 2 MB of Macronix serial flash (25L1606E).
There are no thermal pads connecting the plate to the board, so thermal connection must be made from board inner layers
through the six metal standoffs that connect the plate to the board.
