5 out of 5 eggsawesome!!

Pros: Ok so I ordered this before reading any of the reviews and was a worried that I was going to get another poor working router. Well let me tell you this is the best router I've ever had and believe me I've owned lots. I haven't had to reset this router once yet. The range on both GHz is impeccable! I updated the firmware through the GUI and thought oh great its gonna become a brick and it works perfect. I can't think of anything that is really bad about this router.

Cons: Didn't come with an Ethernet cord, lol but really I have plenty. It feels really warm to the touch but its probably me being a worry wort so I just put a little fan next to it and the modem and now its ice cold

5 out of 5 eggsBest home router I've used

Pros: Easy to use, lots of server features, great signal strength, great reliability, constant updates, much doge, good looking too.

Cons: usb2 for the usb ports. not REALLY a con because the weakest link for most people is going to be the wireless speed and who saturates a 1gbps ethernet link at home ever? sounds like rich people's problems lol.

5 out of 5 eggsGreat Router

Pros: FANTASTIC ROUTER. I turned this router on set it up and been solid ever since on a gig connection. Tests average over 900Mbps WAN to LAN

Cons: there is a common asus problem with port forwarding. it is occasionally hit or miss on port forwarding and any changes applied to the port forward require an imediate reboot.

Other Thoughts: Would recommend this router to anyone wanting a router. DD-WRT, Tomato, open WRT, and Merlin support. keep in mind DD-WRT limits Wan to Lan to 100Mbps

1 out of 5 eggs11 months in and highly disappointed

Pros: it worked for 11 months.

Cons: after 11 months of use, one day the wireless light went off and all the devices in my home on the network went down. smart tv, computer, smartphone, wireless speakers... everything. i contact asus, and asus gave me an RMA and told me to ship it to them. which i did. after waiting about 2 weeks. i contacted them via phone and they assured me they would give me an email soon. I got an email saying that the repair cost was 120 dollars. MIND YOU i paid newegg about 160 bucks 11 months ago. so i was upset and called asus. they said they have policies and my product was no longer under warranty. i called newegg and newegg was reluctant as well.

if someone pays 160 dollars for a router. that person would expect the best. right? for a 160 dollar router to NOT work then the company telling me to ship it and asking for 120 dollars was NOT acceptable.

INCEPTION: turns out this product was refurbished and the warranty was 3 months.

asus confirmed that they refurbished this product. so a product from this company, refurbished or not, doesn't last a year. it is truly disappointing. i am not sure who are the theives. newegg for charing 160 bucks for a refurbished product that won't last a year... or asus for producing and putting their stamp on a product... letting it out of their store.. out of their hands... with the intention of only fixing it if it breaks in 3 months.

no one is willing to step in my shoes and sympathize with my situation. i guess the price different between a new one at 200 dollar versus a refurbished one at 160 is so the company has an excuse to refuse to stand by their product or a company refusing to help a customer who bought it from them.

Other Thoughts: technology is very finicky. i understand a laptop where it's being carried around and has a chance of accidental damage being exempt from this.. but a router that sits at home... the one i had that looked brand new as the day i bought it. it breaks in a year. and no one is willing to help the customer who paid 160 bucks for it. it's a shame. it's a REAL shame.

if the chances of this product being broken were that high... newegg should advertise that since this is refurbished... it can break and there is little anyone can do after that. this may stop other people from making the same mistake i made. both newegg and asus disappointed me.

5 out of 5 eggsSo Far So Good

Pros: Alot. I like the style and I like the material they used. I like how little desk space it takes up given it's size. I like the CD-less setup, I like the fact that the "Guest Network" is defaulted to off and doesn't require a CD to change this setting (I'm looking at you Cisco E1000). I like the web-interface more than any router I've ever used. I LOVE the range. (I walked away from my desk, out of my office, down my hallway, out my apartment door, down a flight of steps, down another hallway, out the apartment building, 25 yards to my car and both my Anroid phone and my wife's iPhone had 4.5-5 bars.) The throughput is unreal. With my old low-end router I had trouble streaming a video in HD with a 30mbps download and even YouTube videos took 5-7 seconds to buffer non-HD. With the new device I have multiple devices streaming flawlessly with HD content and the buffering time is literally non-existant. I drag to the 5 minute mark, DONE, then the 7, DONE. It doesn't even pause while doing this. I haven't used, and may not ever use, the Aicloud so I can't say much about it. I config'ed this router to match my previous router's config and I've had no issues with my new equipment "just working".

Cons: It's expensive. I think it's worth the money, but it is expensive and I got mine on sale for 175$.

My honest opinion is in Other Thoughts regarding cons.

Other Thoughts: I want to preface by saying that these comments are NOT regarding this product. Newegg used to be a site comprised mostly of Techie's. I'm thankful that Newegg has become as successful as it is but this comes with drawbacks. It has really been apparent as I have recently spent quite a bit of time on this sight while building a few gaming rigs and ordering equipment for my office that the reviews simply are not what they used to be. I honestly can't count how many times I've read posts where the reviewer gave a good product 1 egg because it was defective and then continued to list his build / components which were positively incompatible with the product he was trashing. Just today I read a review about THIS router where a user took off 2 stars because the default ip was unlike his previous Linksys which was .0.1. He explained how he had to go to each device and gruelingly alter the wireless connection. He gave the product a 3/5 rating and went on to say his tech level was a 4 or 5!!! Posts like this make the review portion of this website horribly inaccurate and that's unfortunate because that was a HUGE plus to shopping on this site. I'm not upset with anyone and don't "blame them" for "ruining" this site, (Newegg still rules!) but I do want to point out that the reviews on this site can now be taken with a grain of salt. =/ I'm truly sorry to those of you who had DoA's and I would never blame you for the defects of a product. What I WILL say is that I've been shopping on this site for almost 10 years and during the course of this time I HAVE NEVER HAD A DOA EVER. I know they exist, I know Quality Control can't be perfect, but I also KNOW that the actual % of "DoA's" are hugely inflated by well-intended yet uninformed reviewers.

5 out of 5 eggsGood Buy

Pros: Improved reception significantly throughout the house, even with the previous N router there was some areas of very poor reception, due to the only practical placement for the wireless being one of exterior walls. Arrived in great shape and no worries despite being a refurbished model

Cons: Vulnerabilities in the FTP features in the Firmware installed when shipped, make sure you get the update from asus' site

1 out of 5 eggsNevermind

Pros: None

Cons: 5ghz just does not work.

Other Thoughts: My initial review was 3 eggs, but forget that. I dropped over $100 on this and would like some feedback from ASUS.

Manufacturer Response:

Dear Valued Customer,

Where do you normally place your router? If you plan to use 5 Ghz, please ensure that there are no obstruction as 5 Ghz signals are much weaker than 2.4 Ghz signals that they don’t even pass through walls or ceilings unlike 2.4 Ghz. If you have a device that is 5 Ghz capable, please ensure that this device is properly configured and it’s in close proximity. If you’d like to discuss this topic with me please contact me at and include case#3596875 in the subject line. ASUS Customer Loyalty is here to listen and respond to your concerns and to help you with a positive ASUS experience.

3 out of 5 eggs

Pros: Setup is quick and easy, has a lot of options and features.

Cons: Unfortunately, the 5ghz connection keeps dying on me. It will initially be broadcasting, then it disappears.

Other Thoughts: I bought this refurbished, and maybe that is why the 5ghz isn't work. But I am still disappointed.

1 out of 5 eggsGreat for the 2-3 minutes that it'll work for...

Pros: Excellent wireless range and speed for the few minute intervals that it works for.

Cons: The "recertified" router I received had a very difficult time obtaining an IP address from my SB6121 at home, and would cause the modem to power cycle every 2-3 minutes.

I walked over to my neighbor's place and it did the same thing with their SB6141.

The {brand redacted but definitely not ASUS} router that it was supposed to replace doesn't have either of these issues, so I'm back on that until I the RMA goes through.

Other Thoughts: I wonder if ASUS actually tests these things, or just repackages them and sends them out to new customers. Maybe if one more person returns this thing, they will actually take a look at it, or at least not ship it to yet another person.

5 out of 5 eggsGreat router

Pros: Its fast and has great coverage. A few of the newer firmwares are not reliable though. The older one that came with it worked better for me. But I got the latest firmware and its been stable. The user interface is super easy to use. Took maybe 5 min after I opened it until all the computers in the house were connected. Plus you can set up ASUS cloud which is like your own dropbox.

Cons: None so far.
