ASUS EA-N66 or an alien pyramid
Introduction
When the vendor gave us the ASUS RT-N66U wireless router, he added a small beautiful
device – ASUS EA-N66 that combines the functions of a wireless adaptor, an access point and
a repeater. We found it quite interesting and decided to devote a whole review to EA-N66 that
we here offer to our readers.
External design and hardware
ASUS EA-N66 looks like a pyramid made of matte grey and shiny black plastic – a product of
an alien civilization. Its dimensions are 122x111x62 mm and its mass is only 110 gr. For its
operation ASUS EA-N66 requires a 12 V and 1 A external power adaptor.

Web-interface review
EA-N66 web-interface design is characteristic of ASUS-WRT firmware – it’s performed in dark
colors and is available in eleven languages. As the device web-interface in the wireless client
mode has only a minimum number of settings we’re going to study all menu points.
The Quick Internet Setup allows choosing the device operation mode and configuring essential
connection settings.

It’s time to finish our review of the command line interface abilities.
Testing
The first traditional test is to detect the device booting time under which we mean the time
interval between switching power on and receiving the first echo-reply via ICMP. ASUS EA-N66
boots within 36 seconds. We consider it a good result.
Later on we checked the security of the device by means of Positive Technologies XSpider 7.7
(Demo build 3100) network security scanner. All in all we detected six open ports: TCP-23
(Telnet), TCP-53 (DNS), UDP-53 (DNS), TCP-80 (HTTP), TCP-9998 and TCP-18017 (HTTP).
The most significant findings are displayed below.

Conclusion
We liked the multifunctional wireless device ASUS EA-N66 mostly because of its unusual
futuristic design – never before have we seen such a case shape and the demonstrated data
transmission speeds. At the time of writing the article the wireless adapter ASUS EA-N66 hasn’t
been officially sold in Russia yet, that is why by the time of its sales the vendor promises to
have eliminated a range of insignificant drawbacks that are usual for product demo-version. We
consider incomplete translation of the web-interface and incorrect Russian time zones to be one
of such disadvantages.
ASUS EA-N66 strong points are enumerated below.

Stylish design.
Switchable LEDs.
Dual-band (2.4 and 5 GHz) support.
High speeds of data transmission.
Unfortunately, we can’t help mentioning the drawbacks either.
- No IPv6 support.
- No utilities.
Some more attention should be paid to the fact that EA-N66 can work simultaneously in only
one range unlike RT-N66U which lets wireless clients of the range 2.4 GHz as well as 5GHz
connect at a time.
At the moment of writing the article ASUS EA-N66 wasn’t sold in Russia, that’s why it is too
early to speak about the price.
