5 out of 5 eggsGreat range and stability

Pros: - Great Range, I get full signal at rought 50' through a wood floor and four or more walls (2.4 and 5Ghz N).
- Rock solid stability! I updated the firmware after purchasing the router and it's been running 24/7 for roughly 6 months without a reboot.
- Tons of bandwidth for LAN. I'm supporting one server and 10 client devices for file, app, and streaming media services without issue.
- Easy to use! It's true this router can get complicated if you leverage some of the more advanced networking features but for most purposes it just works.

Cons: - Slow when used as a file server with a external drive connected. No issue for me, I use a home server.

Other Thoughts: If you don't need AC and/or file services hosted from the router, and most people don't, this is the router to have. It was easy to setup, has great range, and is rock solid stable with the latest firmware.

Most important for me was range. I didn't want to run a complex, multi-router config at my house. Based on the routers I tried prevously I didn't think that would be possible. Anyway, I rolled the dice and this router has worked out perfectly!

2 out of 5 eggsDropped Connections

Pros: Worked well for the first couple of months.

Cons: After firmware updates, the router started dropping connections. Reboot router, and the router would work for a couple of hours before starting to drop connections again. It's now to the point that connections drop continuously even when it's rebooted. At first I thought it was my internet provider, however removing the router, and connecting directly to the modem fixed all the dropped connections.

Other Thoughts: Was great while it lasted, but for the price.... NO WAY. I'm not in the business to "RENT" a router.

2 out of 5 eggsASUS Router does not hold up

Pros: This ASUS Router (RT-N66U) performed flawlessly for the first year and five months. Really good software.

And when you have a problem you can get a human on the phone.

Cons: It failed without warning, dead and will not light up.

It gave no warning and worked fine yesterday but died sometime overnight. It was purchased new from Newegg Feb 2013 and did not make it past 18 months.

The Router was plugged into a battery ups for protection along with a cable modem and switch. The other equipment is still working without problems so I feel sure it was not a surge or power sag that caused this.

Other Thoughts: This was the top ASUS router at the time and I felt like it was worth the money then. The 2 year warranty also seemed to be a good selling point.

And, I do appreciate that they answer their phones, the customer support was solid.

What they do not tell you is that you have to RMA (return) the Router for inspection and repair (not outright replacement). I can understand their being cautious but whatever happened to "cross shipping".

If your Router dies, how long does ASUS expect you to be without a Router? No clue on how long this will take or when they will get around to fixing my Router.

But, wait I have an old (slow) D-Link Router that I have set up to temporarily have a network at home. This thing has been around for ages and I loaned it out when some friends had router problems. Hmmmm..., I may have bought the wrong brand of Router.

5 out of 5 eggsGreat router

Pros: Easy to setup
Great range
Custom Firmware
Looks great

Cons: None that I can think of.

Other Thoughts: Bought this to replace an n56u, which also worked great for over a year. Needed a new router for my mom's house so I replaced mine and gave her the n56u. Able to get signal throughout my house and the 5ghz signal reaches my car (not that I'll need it that far). The 2.4ghz signal can reach pretty far down the street and still have decent signal. Have no problems getting my full internet speed 50/5mbps with this router. If you have a small house get the n56u, if you need more range then get the n66u.

5 out of 5 eggsGreat Router

Pros: Solid connectivity on assorted Windows, Android and IOS gadgets, probably 30 different things have been hooked up to this network from the extended family. Usually we are running 2 desktops wired, an OOMA IP phone adapter wired, 2 laptops wireless, an HTPC wireless, 2 Rokus, a Chromecast, 4 phones, a wireless printer and 2 tablets through it on 100mps service. Everything works 100% of the time.

Cons: Looses all those MAC address I put in for the MAC filter when updated. If you use a MAC filter, be aware and save them separately, the onboard backup facility doesn't get them. Fortunately the whole thing can be done using cut and paste steps. Only has 4 wired ports and I have to use a hub in the basement.

Other Thoughts: 2 firmware updates in the last year, both went smoothly, but use the onboard backup tool to make things easier.

3 out of 5 eggsInconsistent Quality

Pros: With a good unit- great performance. All the features just work. Good fast wired and wireless connections. Not much more I can say.

Cons: Incosistent Quality. I own two of these. I liked the first one so much, I bought a second one. At first it seemed to be just as good as the first one. The I realized it runs MUCH hotter. I also found that my wireless connections are not stable- especially the 2.4 GHZ band. I out the unit on top of a fan- it runs really cool now, but the wireless connection issues persist.

5 out of 5 eggsWow, wow, wow!

Pros: To repeat my title: wow. I never realized the upgrade this would be. I was using a WNDR3400 flashed with DD-WRT for a very long time. It was completely stable and I had the control I wanted. I didn’t think I’d ever find a replacement… until this router.

The reason I purchased this router is due to a very large upgrade to a 105 Mbps internet package. The WNDR3400 doesn’t have the hardware for that kind of speeds, so the time had finally come to put my trusty router to the side and let a new one take over. I had actually heard a lot of buzz about the RT-N66U for a long time, so headed to Newegg and purchased it. I was excited when it came in, and immediately got started hooking it up.

After going through the somewhat lengthy web interface process to connect the router to the internet, the very first thing I did, like most people, was speed test. The WNDR3400 got 67-70 Mbps down on average, and the RT-N66U blew that away with a solid 117 Mbps down. Again: wow.

Moving into wireless, the range on both the 5 GHz and 2.4 GHz bands is phenomenal. I have coverage waaaaaay outside my apartment. My apartment is a box shape with a large courtyard in the center of the box, and I seem to have useable signal in the entire courtyard. The router is not facing a window or anything, so I suppose this is a perfect combination of a powerful router with no major obstructions in the walls.

I’m impressed, to say the very least.

Cons: No major cons. I wish the plastic piece that stands the router up vertically worked, but it does not. It seems like the router gets pretty hot horizontally, but as I am the often the only user and I can only provide so much load (though I do give it quite a bit of traffic to handle).

Flashing DD-WRT is a little nerve-wracking on this one. It seems like there was an issue with dealing with 64k NVRAM, but the new K3.X builds solve this issue.

Other Thoughts: The default firmware and DD-WRT perform about equally, though it actually seems like I got faster speeds from the stock firmware. However, I’ve been tweaking a bit and I’m getting closer to the speeds on stock. Both had similar wireless ranges, and the UI was much flashier in the stock (which I don’t need).

You will not be disappointed in this router. You will want to tell your friends, your neighbors, your classmates, and your coworkers, about how awesome this router is and how you wished your ISP could fulfill the speeds it can handle. One day you’ll get the chance, and it’ll be a great day!

1 out of 5 eggsbuying another router today

Pros: Great wifi range, adequate speed

Cons: Randomly drops internet connection, as experienced by other reviewers. I should have listened to them.

Other Thoughts: Great unit if you want to take a chance on it not working well. One odd thing, mine has entries in the system log from January, May, and December 3013 -- I didn't buy the unit until May 18, 2014. Maybe it was a refurb? I won't take a chance with another one. Wish me luck, I went to Netgear.

5 out of 5 eggsAwesome

Pros: +Dual band means you can rout 2.4GHz and 5Ghz signals simultaneously.
+2 USB ports make printer and storage sharing seamless and easy.
+Router utility has many useful options like VPN and USB app.

Cons: None.

Other Thoughts: I bought this router to replace a Linksys WRT-300N. I have a Comcast Blast tier so my download speed was getting capped at about 55 mb/s. After I replaced the router the wired download speed jumped to 103 mb/s and my wireless speed topped at 105 mb/s. Go figure.
