Apologies to Lewis Carroll. I'm afraid the following doesn't scan as
well as his version:
"The time has come," my router said, "to talk of many things.
Of 802.11 ac and n and g and b,
And why Cisco updates without permission.
And the safety of ASUS settings."
:-)
It's long past time for me to replace my 802.11 g router with something
more recent. But I have a few constraints that make it tricky to select
the right router. So my question is, do any of you have experience with
the ASUS RT-N66U or any other router that fits the constraints I
describe below? While I'm interested in recommendations of what's
worked well for you, I'd also appreciate warnings of what to stay away
from. advTHANKSance for your help.
My constraints are:
1. COVERAGE:
The construction of the house the router will be installed in is
problematic WRT getting signals through. It was built before
drywall was in common use in the U.S. But rather than using wood
lath, the plaster is held in place by lath. But it's not
traditional wood lath. It's WIRE LATH. Also, the heating system is
forced hot air, which means that there's SHEET-METAL DUCTWORK
between all the ceilings and floors.
So all the walls, floors, and ceilings have metal in them.
With the old router, I had to replace one of the stick antennas with
a directional antenna aimed toward the part of the house where
coverage was weakest. But since 802.11 N and AC use MIMO, I believe
that replacing one of the stick antennas with a directional antenna
would screw up the interference pattern that MIMO depends on.
I'm hoping that MIMO will solve the coverage problem that the
directional antenna solved with the old router.
Do any of you have any experience with routers in environments like
this? If MIMO doesn't get me the coverage I need, what are my options?
2. N vs. AC:
I have a 5 GHz cordless phone that I do not want to replace. It
implements features that would be difficult to find a replacement
for, and even if I could, replacing it would be quite expensive. So
it was important for me to figure out whether this phone will
interfere with an 802.11-AC router. It took several months of
research, but eventually I determined that it definitely will
interfere with over half of the 5 GHz WiFi channels used in the U.S.
Since 802.11-AC only operates in the 5 GHz band, but 802.11-N
operates in both the 2.4 GHz and 5 GHz bands, 802.11-N seems like a
much better choice for my circumstances.
Furthermore, most of the computers on my network don't support
802.11-AC, but are recent enough that I'm not likely to replace them
anytime soon.
So it makes sense to me to ignore 802.11-AC routers and only look at
802.11-N. Does this logic make sense to you?
3. SPEED:
Of the 802.11-N offerings, the highest aggregate speed seems to be
450 Mbps in the 2.4 GHz band plus 450 Mbps in the 5 GHz band. This
is commonly known as an N900 router. Given the potential
interference from the 5 GHz cordless phone, I may not get the full
450 Mbps from the 5 GHz range, but a dual band N router seems the
choice most likely to get me the fastest throughput possible for my
circumstances.
4. PORTS:
In addition to supporting WiFi, I also need the router to provide 4
LAN Ethernet ports in addition to the 1 WAN Ethernet port for
connecting it to my cable modem.
5. WHAT ROUTERS CAN BE TRUSTED?
CISCO: Given the above constraints, I was considering the Linksys
(Cisco) EA4500, but when I Googled it, I quickly learned that about
2 years ago, Cisco/Linksys had pushed out their Cloud Connect
firmware to all their routers without the router owners' permission,
and in order for the owner to continue using his own router, he had
no choice but to sign an agreement that allows Cisco to spy on his
Internet use, allows Cisco to sell any data they collect, and allows
Cisco to legally lock the router's owner out of his own router
whenever they feel like it.

http://www.extremetech.com/computing/132142-ciscos-cloud-vision-mandatory-monetized-and-killed-at-their-discretion
Even though they eventually changed their policy, they have reserved
the right to change it back, and also the right to change how your
router works, EVEN IF YOU SET IT NOT TO ACCEPT AUTOMATIC UPDATES.
I will never again in my life trust anything Cisco/Linksys says or
have anything to do with any of their equipment.
ASUS: The next router I've been considering is the ASUS RT-N66U.
But Googling for that model turned up the following articles:
http://arstechnica.com/security/2014/02/dear-asus-router-user-youve-been-pwned-thanks-to-easily-exploited-flaw
http://nullfluid.com/asusgate.txt,
http://blogs.law.harvard.edu/zeroday/2014/02/05/so-this-is-what-getting-pwned-is-like
It sounds like ASUS was informed of a major security flaw in their
firmware, and chose to bury their head in the sand instead of fixing
the problem. While not the best behavior, it's nowhere near as
egregious as Cisco's behavior.
Have any of you seen other router manufacturers trying to seize
control of the hardware, either like Cisco tried to do, or in some
other fashion? If so, which manufacturers, and what have they done?
