Pros: Very good coverage and speed when it worked.

Cons: Failed after short warranty expired. It gets very hot causing it to lock up.
Really disappointed in this product after owning severa very good Asus routers including the RT-N66R which this replaced.

Other Thoughts: If you do purchase really try stress test in before the warranty runs out. There appears to be an issue which I suspect is why there are so many refurbs.

Dear Seamus,

We want to extend our sincerest apology for any inconvenience this has caused you. I certainly understand your concern regarding the overheating router and warranty process. In regards to the overheating router, please use the following troubleshooting steps to adjust the power to avoid overheating or please place the router in a cool, ventilated and dry area.

Step 1. Please access the router interface, to access it, please open a browser and type into your address bar 192.168.1.1 and if it's asking "Authentication required" please key in your router log in.
Step 2. On the router interface, please look "Wireless" under "Advance Settings, " > click the Professional tab> please scroll down and look for "TX Power Adjustment" as default it's currently 100mW, please put it to 70/80mW, then click apply and reboot the router.

For the latest firmware version of this model, please try to upgrade it manually, you can download that on our website at support.asus.com.

Pros: Security is good with options for multiple passwords for different bands. Signal strength is fantastic!

Cons: Only lasted under two years versus my D-Link that I had previous for 6 years and was still going. I just wanted to upgrade. During the under two years there were many problems from day one. Every couple months I had to change settings because the speed would drop to 2-3 GB while connected to the modem directly I was getting 17 GB. To spend 150.00 like I did and it go out less then two years I probably won't be buying a ASUS again.

Other Thoughts: I was hoping ASUS would understand but there customer service was very bad at the time but seems like they may have improved a little from my last call but Still not help me on this Junk router.

Pros: When they work, they work well. I had a RT-AC66R running in media bridge mode connected to an RT-AC68U. When connected, it would run for months without issue. Never had to reset either router. The Netgear WNCE4004 media bridge would always need to be reset.

Cons: Reliability is suspect, especially on refurbished systems. My first
AC66R refurb lasted a couple years, but my APC Back UPS XS1500 threw an F02 error and shut down. After that, the router was too flaky to use. I ordered a refurb to replace it, but on arrival, the 5G was only reading 90dBm from about 3 ft away with Wifi Analyzer. I also couldn't connect to it using 5G, so it is going back.

Dear David,

Thank you for your time on posting this review, we are sorry to hear your experience with the ASUS router. Please allow me to assist you.

I understand that you are disappointed by the router's performance that's why you are returning it. However, have you tried updating or downgrading the router's firmware? changing settings like changing channel bandwith or repositioning the router just to try to fix the router's connection issue.

If there is anything else that I can help or assist you with your unit, please email me at customerloyalty@asus.com and put case #N151066047 in the subject line for a reference.

Pros: Worked great for about 9 months.

Cons: Router suddenly died and I didn't realize there was only a 90 day warranty. I called Asus to see if there was anything they could do, they were less than useless. And to anyone considering buying this here's a little info that Newegg or Asus fails to disclose, the 90 day warranty starts the day it leaves Asus, NOT the day you purchase it. So if it sits in a Newegg warehouse for 3 months, there is no warranty. My warranty expired 2 weeks after I bought the card.This came straight from Asus support.

Other Thoughts: I love Asus products, I have several, but this has left such a bad taste in my mouth that I have eliminated Asus video cards from my upcoming purchase of one, and I seriously doubt I will ever buy Asus again.

Pros: Looks great, worked nicely while it worked.

Cons: Didn't work for very long. It was overheating and stopped working until I disconnected it for an hour or more and reset everything to get it going again for a few minutes. It has great features however doesn't execute well its primary function. I don't recommend this model if you're going to move into the AC class routers. There's better out there.

Other Thoughts: Don't waste your money. I bought it and have regrets since.

Dear Dariusz,

Thank you for your time on posting this review, we are sorry to hear your experience with the ASUS router. Please allow me to assist you.

First can we have the unit's serial number for me to check it's warranty and in case I need to process an RMA. How many hours do you usually use the router? are you only using it for wireless connection? please check if there's any loose physical connection that can cause the router from overheating.

If you need further technical assistance or if you want to discuss this matter with me, please email me at customerloyalty@asus.com and put case #N151066559 in the subject line for a reference.

Manufacturer Response:

Dear Bryan,

Thank you for posting this review and for using one of our products. I want to apologize for the inconvenience it has caused you. I understand that you're having an issue with the router firmware. To isolate this case, have you tried to update the firmware version and do a factory reset to see if that will help with the issue? If not, can you please try to do it manually upgrading the firmware version.

First, download the latest version on this link: http://support.asus.com/Download.aspx?SLanguage=en&m=RT-AC66R&p=11&s=2

Here's the steps for manually upgrading the firmware version:
1. Click "Global" to download.
2. Once it successfully downloaded, please extract the file.
3. Plug in the router to PC hardwired, please access the router interface using 192.168.1.1 and key in your username & password for your router log in (as default the username and password is admin/admin).
3. On your router interface, please look "Administration" under Advance Settings and click the Firmware Upgrade tab.
4. Administration - Firmware Upgrade, please click "Choose File" (make sure that the file that you are going to uploading is the "Extract File") then click Upload.
5. Once it's completed, please hard reset the router to update the router settings. Make sure to create a new different Wireless Name/SSID for 2.4GHz and 5GHz to avoid wireless conflict. You can still provide the same password for your Wi-Fi.

If the problem still persists, please email me at customerloyalty@asus.com and put case # N151038263 in the subject line for your reference.

Pros: This is a great router. I didn't pay an arm and a leg for it and haven't had any major issues in over a year of ownership. It reaches every part of my house great except for the master bedroom, which is the furthest point from the router and I have a lot of things that could interfere with the signal (plaster walls, other signals, etc).

Cons: Sometimes I will lose signal in areas of the house that I know have good strength. This is likely just from something interfering with the signal and I just need to tinker with the antennas or buy a range extender (like another of these!)

Pros: Bought it a few months ago and was very happy with the range and speed. I have a 4 story townhouse so I needed a nice router to get wireless to the other floor and this one finally got the job done.

Cons: Woke up this morning to find it totally BRICKED! Do not buy this product its not worth it. I'm now stuck with a 150 dollar paper weight and no internet. The WAN, 1, and 2 port lights are stuck on. I have tried everyting, computer wont even connect to ports.

90 day warranty is not long enough, just save your money and get something else.

VERY UNHAPPY!!!

Other Thoughts: The refurbished 90 day warranty is not long enough and if I just went with a new one It would be covered.

Pros: When it was working, wi-fi was more stable and had longer range than my old router.

Cons: Router forgets its configuration and reverts back to the defaults after a few days of operation.

Other Thoughts: I have worked both sides of an IT support desk, and this is the absolute worst experience I have ever had. A router that loses its configuration and disconnects from the Internet every few days is not at all useful to me. I contacted Asus Support while the warranty was still in effect and did everything that was asked. Due to the nature of the problem, the 90 day warranty had expired when Asus finally granted me an RMA number. After I paid to ship the router back, Asus wanted an additional $130 to fix it out of warranty (which is more than I paid for it to begin with) which I refuse to pay. Visa was no help either. Asus is shipping it back where it will promptly find its way to the garbage. The lessons I’ve learned is to make sure to thoroughly test and burn in the product while Newegg’s return policy is still in effect and to think twice before buying another Asus product again.
