1 out of 5 eggsHidden Defects. Poor Firmware

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: If you have nothing better to do and enjoy spending quality time with routers that don't quite work properly, this is the product for you. This router will taunt you then ignore your safe words. You just have to put up with it's punishment until it's finished with you. Unfortunately, I'm not into this stuff, but maybe you're up for it.

Cons: This router has intermittent connectivity issues. It will work fine for a day, then disconnect for no reason and will be difficult to reconnect. Tried the factory reset multiple times but with no luck. Tried upgrading the firmware but it made the problem worse by disallowing static LAN settings. Seems like the firmware has major flaws.

1 out of 5 eggsDoes not run warm... runs HOT

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: - It does transfer data at speeds I would hope

Cons: - It runs hot. Not warm, HOT.
- Anything running that hot, is wasting power and doesn't seem good.

Other Thoughts: - Not warm, hot. Very hot. Leave it in the open, with airflow and don't put anything on it.

2 out of 5 eggsI hate this router

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: looks cool

Cons: drops out constantly. USB connection does not work for anything more than a low capacity memory stick. Spotty service

Other Thoughts: Huge regret of a purchase. I hate this router. I limped it along for years and it progressively degraded. ANd it never worked well to begin with. I now have a cheapo that was 1/3 its price and it runs circles around it.

4 out of 5 eggsPretty good, but only with DD-WRT

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: It's a simultaneous dual-band router, which is nice when you still have devices that only work on the 2.4 GHz band. A lot of access points will only run one band at a time, even if it's capable of both.

It's got a good range. My previous access point had trouble reaching from the basement to the second floor, but with this one I get a good (or at least good enough) signal throughout the house.

Installing DD-WRT is possible, but it's harder than it should be, especially for a router that advertises it.

Cons: The stock firmware is flaky. It goes out to lunch a lot and you have to reboot it to get it working again.

The configuration interface is too limited. For example, dnsmasq (the DHCP server and DNS relay that it uses) has an option to assign a specific name to a specific IP address, but there's no way to get that option through the user interface.

On top of that, the interface is slow and cumbersome, like they spent more time trying to make it pretty than they spent making it functional.

Despite its claims, the wifi speed tops out at around 45 Mpbs or so.

Other Thoughts: It's a good router, but only if you replace the firmware. After I put DD-WRT on it, it's worked like a charm.

The wireless performance is good enough I find, and it's about as good as I would expect. The computers in my network that need a fast connection are all wired.

2 out of 5 eggsWorked good for a little bit

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Looks nice, worked well, when it worked, has a stand so it can lay down or stand up. Had good distance.

Cons: Purchased this in 8/2014. Worked good until about January 2015 then it overheated and melted down. ASUS worked with me and I sent this one back and they got me a new one. This new one went out on me about a month ago. So it lasted me about 14 months. I love ASUS items but I don't recommend this one. Decided not to go with them again and got me a Modem/router in one from another company.

5 out of 5 eggsJust excellent

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Fast connection
Huge Range
Stable connection
Beautiful interface and easy to use
Firmware upgrades are fast and easy
Works really well when connected with other Asus Routers
Beautiful design, it will look good in you living room

Cons: Nothing huge...
Will get hot, but this does not affect performance.
It is a dust magnet!

Other Thoughts: Default Firmware version is terrible, just upgrade it and you will have the best router out there
When I bought it was +$120, and it is worth every penny

5 out of 5 eggsWorks great - seems like a great value

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: It seems to have good range and high throughput. It was simple to set up.

Cons: None so far.

Other Thoughts: The end user has some wifi devices, one of which had trouble connecting to a previous router. No complaints with this new router.

2 out of 5 eggsUndependable Wireless

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Looks great. Router and wired functions work well. Firmware updates are very easy. Great specs.

Cons: The unit had to be replaced for failure during the warranty period: not a pleasant experience. Wireless drops connections randomly with both routers. When I bought it three years ago, it was a relatively new product; the reviews had not caught up with its short comings. I would not recommend this product or any other Asus networking device.

Other Thoughts: My order for new a new wireless router and access points has already been placed with Newegg. Needless to say, it is not Asus.

4 out of 5 eggsworks fine until it doesn't, but problem appears to be repairable

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Fairly easy to set up, worked with no problems for almost 2 years.

Cons: Started randomly losing internet connection, then died.

Other Thoughts: Similar problems to what others have written. After a couple years, it started randomly dropping the internet connection. Both wireless and wired connections were affected. After a few minutes, it would re-connect. Now, it seems completely dead. Lights are on as if everything is OK, but no connection, wireless or wired.

UPDATE: I disconnected power for several seconds, then was able to log into the router via a wired connection. I then followed Asus support's directions to update the router's firmware and reset it. It now works again. We'll see how long it lasts.

Note that you can save the router's configuration -- I did this when I originally set it up, which saved a lot of trouble as I could re-load the config after the firmware update and reset. Also, Asus support recommended using different names for 2.4 and 5 GHz wireless, which lets me know which devices are on which band.

3 out of 5 eggsMediocre

This review is from: ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router, DD-WRT Open Source support, IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Ran my network 95% of of the time?

Cons: Ran really hot. Streaming video to 2 or more devices in my household would cause the machine to heat up and become less responsive. If the router was too hot to touch, this usually implied poor networking performance.

Network outages would require the device to be reconfigured from scratch. I have a fairly ordinary cable modem setup, but if my network or DNS went out for any reason, I found it would screw up my router settings royally. The hours of time required to reboot/reconfigure the router settings were just not worth it.

Ships with default login and password of "admin/admin". Never very confident that my hardware was secure.

Other Thoughts: Had to buy another router to address the failings described above.
