5 out of 5 eggsAsus Awesomeness--Again

Pros: There is a reason Asus has such a strong reputation, and I am becoming more and more a fan boy. Bottom line is that this is by far the most stable, easy to set up (but with tons of available options) router we have ever owned. I think I've reset it once in the 8 months we've had it. The three antennae really do make a difference on signal strength/distance in our 2-story house. Just a solid piece of hardware.

Cons: None.

Other Thoughts: Highly recommended. Paired with the Trendnet media bridge that came with it from the Egg as part of a deal, our wireless coverage and stability is the best it's ever been.

5 out of 5 eggsGood for the price

Pros: It came with simple and easy setup and control software/settings, has a good range on 2.4Ghz band, and is reliable and fast.

Cons: The 5Ghz band is fairly disappointing for range, as any device more than 3 walls distant will have very low signal, if any signal at all on that band. This is even with the power on the 5Ghz radio at maximum.

The speed on the 5Ghz band is excellent, just don't expect it to reach from one end of a house to the other...because it won't. I know the 5Ghz band is limited on range, but the huge antennas along with a large and adjustable power setting led me to believe this could be at least somewhat mitigated. It might very well be possible, just not on this device.

Other Thoughts: For the price, I believe it to be a very good buy. It can handle multiple connections with large throughput, and all without a stutter. Of course, this is dependent upon you having your devices allocated relatively equally between the two separate bands.

All in all, it has been reliable and dependable for the 6+ months I have owned it. I especially love the settings for being able to limit the amount of bandwidth/time any particular device/mac address can spend on the network. Asus really did put a lot of thought into the software.

5 out of 5 eggsBest yet...

Pros: Fast, good range, full featured... Have been using WiFi for years, have used, NetGear, LinkSys, etc. This is the best router I've ever owned. Fast speeds, great range in a 1,800 sq ft 1 story ranch. EVERYTHING in my house runs through it. 3 Smart phones, 3 desktops, 4 laptops, 2 Roku's, 3 DTV units, etc. Even using it for unified printing for PC's and Mac's. Waiting for a sale to buy more of them for other family members...

Cons: Runs a little warm, but I solved that by modding the case top with a quiet, low-speed PC fan.

Other Thoughts: I wish other network gear were this reliable...

5 out of 5 eggsBest home router around

Pros: I got two of these and threw one into client mode and the other into routing mode and my household has over 20 devices if you include wireless connected to. Everything works like a dream, a little trouble with lease renewal when ISP leases expired but a firmware update came out and it has been fixed ever since.

The configuration is a dream to use, with basic setup being a cinch and with the ability to modify some of the more advanced settings of networking. I'm very fussy about my network; I need to have everything just so. A router like this one suits me.

Cons: I think it's a bit pricey.

5 out of 5 eggsAwesome Wireless Route

Pros: My old route is from ISP and I replaced with this N900. This is an excellent wireless route, especially for 5G band.

Cons: My ISP is Bell Aliant, using FibreOp, there is little trouble to setting up the route. I called Bell Aliant and ASUS customers services to solve the problem

5 out of 5 eggsWorks Great

Pros: Fast
Easy to setup
A lot of options

Cons: Nothing so far.

Other Thoughts: Bought this to replace my old router that was not giving me full speed via WiFi.
I have not upgraded the firmware but right out of the box, I'm getting full download and upload speed via WiFi and no dropped connections. Very Pleased with product.

3 out of 5 eggsIPv6 is buggy

Pros: Great WIFI coverage.
Intuitive interface for novices.
Features for power users.
Frequent firmware updates.
Developer friendly with open source firmware.

Cons: This router is not IPv6 ready certified, and IPv6 support seems buggy and inconsistent between each firmware release. I've been using Hurricane Electric 6in4 tunnel for a year and got it to work, but I have had no luck with Comcast native IPv6. RT-N66U refuses to route IPv6 packets from LAN when using native IPv6, and it's not Comcast's fault. Computers plugged directly into Comcast's cable modem have working IPv6.

I telnet into RT-N66U and verified that it can ping6 hosts on the Internet (e.g. 2001:4860:4860::8888). Computers on LAN get IPv6 addresses, but they can only ping RT-N66U's IPv6 address, not the cable modem's nor the Internet. It's clearly a routing problem with RT-N66U.

Also, the dhcp6c on RT-N66U often fails to obtain DHCP-PD information due to no route to ff02::1:2, another routing issue, unless I reboot it. This type of flakiness is quite unacceptable.

Other Thoughts: Great router if you don't care about IPv6, but these days IPv6 is imminently inevitable. Make sure you check IPv6 readiness from ipv6ready.org before you buy a router.

I would also have liked if Asus would put this router through the IPv6 certification process, as it would help them iron out IPv6 issues more consistently. The Internet is full of mixed reports regarding IPv6 support of this router, and it's hard to find any useful information what settings and firmware versions work.

4 out of 5 eggsAlmost there

Pros: My setup includes a home server with port forwarding, Dynamic DNS, Gig network, lots of wireless and 2 boys. I have had great experience with the network speed, port forwarding and physical network. I pound this thing pretty often and it works like a champ. QOS was a little too simple, but works.

Cons: Normal amount of reboots, ie unplug and replug. About two or three times a year.
The wireless has some issues with the 5Ghz depending on the firmware you are running. Firmware is still getting released as of this port, so at least they are trying.
Parental Controls are pretty much useless for me. The time restrictions do not work except on new connections. Basically if the boys are online it will not block them until they turn off the computer and turn it back on. Not helpful for a parent who wants to go to bed before them on the weekends.

Other Thoughts: If you have it controlling everything this should be spot on. I was hoping to get an over the top device based on the cost but it is just short. I have not tired the USB ports for anything.

1 out of 5 eggsOk.....But...Unacceptable

Pros: We purchased this in April of 2014. Reliable and good speeds, no issues until....(read Cons below)

Cons: The 5ghz completely dropped out and is not usable. Search this issue on the internet before buying. You will see it is a very common issue. 2.4ghz is still operable, but unacceptable as the unit should have all features functioning. ASUS appears to not have come up with a solution or a lack of concern as of yet and many are in the same situation. I/we are currently shopping for another wireless router.

2 out of 5 eggsInconsistent, slow uploads/downloads via wi-fi.

Pros: Gigabit LAN working well from what I saw. Was getting ~25MB/s from an old AMD Duron 900 pc with an Intel PCI Gigabit LAN card to my Crosshair V Formula Z, transferring files via Samba. No doubt, the bottleneck is the Duron itself and its old IDE HDD. If I had another gigabit capable device, I could have tested it further.

USB ports for sharing files, printer sharing, torrenting, etc. Feels well made. Slim and sleek (compared to my WRT54GSv4). Dark color (no wonder it's called "Dark Knight"). Would win a beauty contest against the Linksys WRT54G/S/L series.

3x detachable antennas. Great for people who want to hook up Yagi antennas for some fun, long distance wireless links. Great for swapping on aftermarket omni-directional antennas. The antenna connector type is RP-SMA.

Cons: Wi-fi speeds are very unreliable and slow. Packet loss on stock firmware (~10-13% pinging router over wifi). For the 5GHz band, one minute the link is at 450Mbit/s, the next, it's at 24Mbit/s. It stays fine for a few minutes after rebooting, but goes back to terrible speeds soon after.

Transferring files via Samba over wi-fi gives me only 1.6MB/s (megaBYTES/second) to my main pc from my HTPC in the living room (literally the next room), which has a WUSB600Nv1 wi-fi N adapter connected to a USB2 port. That is unacceptable. Even my WRT54GSv4 can push out ~2.2MB/s, and that's a wireless G router from 2002! over a decade old device performing better than a top of the line, $100+ router! Then again, ~2.5MB/s is pretty much the maximum that a wireless G router can transfer anyway, and that's counting in the fact that my WRT54GS is overclocked to 252MHz.

Router VERY warm to the touch. Not dangerously warm, but VERY warm. Asus should have increased the width of the router just a little bit so to fit small 40mm fans on the side. Or increased the height just a little bit and placed a small fan on top that would blow air out of the side vents should the temperatures get warm enough to impede wireless and wired performance.

Other Thoughts: I tried downgrading the Asus firmware one version below. Didn't make a difference. Flashed back to the current firmware which it came with. Didn't make a difference. Will RMA for a refund. No doubt shipping will have to be paid out of my pocket. I'll use the money to get a GTX 650 for my sister's cheapo gaming pc. The Zotac GTX 650 is selling for $60 on this site. The router can wait.

(I have an Asus Crosshair V Formula Z motherboard that has been working great for over a year now. I'm certain I just got a dud with this router).
