3 out of 5 eggsMeh

Pros: Interface is clean and responsive
Has just about every feature you could want with a few major exceptions -- see Cons
Wired speeds (non-routing) were tested to be 935Mbps

Cons: There are some really goofy limitations with the router such as:
- No description field for DHCP reservations -- you get MAC and IP, that's it.
- Router remote admin IP restrictions must be individually defined for both external and internal address and you can't do wildcards or networks. You're limited to 4 IPs.
- Can't edit port forwarding, must delete and re-add.
- Cannot access port-forwarded services from inside the LAN. This means you have to setup two different connections for services, one using local DNS/IP, other using public DNS/IP.
WAN port can't be used as a LAN connection when in Media Bridge mode.
10 feet away, connection between two of these routers is 1200Mbps. WTH?
No VLAN support. This can be a deal-breaker for many people, including myself (the user I implimited these for doesn't use VLANs).

5 out of 5 eggsWork Great and Easy To use

Pros: -Fast
-Long Range
-Easy to use interface
-Features, features, features
-As future proof as you can get (for now)
-Work for both PC and Mac

Cons: -Expensive (but you get what you pay for)
-USB 3.0 port is on the front instead of the back, (good if you are plugging in and unplugging frequently but doesn't make a lot of sense and ugly for external storage)
-1 USB 3.0 and 1 USB 2.0 - I would expect that both USB ports should be USB 3.0. While the USB 2.0 is most likely for a printer on a top of the line product like this both ports should be USB 3.0

Other Thoughts: Hopefully this is obvious but to get the speed out of this you need to use with with other AC capable devices.

I was looking at this router for a long time trying to decide if it was worth the money and finally took the leap and am glad that I did. This router has more features and options than you are likely to need, but it has a great user interface that makes all the features easy to use and easy to figure out.

This router is bigger than most. I don't think it is a bad thing, but something to be aware of.

The router has setting specifically for using it for Time Machine with Macs.

I would like to see more ethernet ports on the high end routers like this. It has the standard 4 ports but I would love to see 6 or 8 just so that I will have extra.

1 out of 5 eggsBricked by firmware update.

Pros: * Wifi penetration was great.
* 5GHz band is really really fast.
* Extremely configurable, pretty much every option you'd want.
* Awful English localization of onboard web server text kept me chuckling during configuration and troubleshooting.

Cons: * Worked fine for about a week or so, then it wanted a firmware update. The update succeeded, but then: 5GHz radio wouldn't power on (according to internal system logs), ISP wouldn't give it DNS (according to the router), physical LAN ports stopped working (wired devices weren't getting DHCP and wifi-connected devices couldn't ping wired devices that had static IPs).

* Onboard web server is in totally broken English, localization is embarrassingly poor.

* Onboard web server UI / UX spends most of its effort on silly chrome instead of information presentation. It's unclear which wifi you're configuring (5GHz, 2.4GHz, or guest). There's no onboard search, which is necessary because of the number of configuration options (don't make me memorize or google where to find things).

Other Thoughts: I plugged my 2008 Apple Airport Extreme back in after the ASUS self-destructed and everything (wifi + wired + backhaul) worked again.

With product experiences this black and white I have no interest in engaging ASUS for customer support. I got a brick or a bad firmware update; I don't care which. I RMA'd the unit and am buying a new Airport Extreme.

Pros: Quick and straightforward. All needed information found quickly. Product support is reasonably good for the price.

Cons: Not absolutely certain about the effectiveness of the security and the simplicity of use until I've received the product to test it out.

4 out of 5 eggsVERY GOOD

Pros: All the features and more one would want in an Office or Home.
Performance is outstanding and the range too.
A must for Families who have teenage sons, and the, ahemm, 'gentlemen sites they visit.'

Cons: IPV6 is a problem with this and ASUS you need to fix it. My lower cost 66u performed symmetrical with IPV6 & IPV4, this monster cuts the Download on IPV6 by 1/2. I get 125MbPS Down with IPV4 and only 65MbPS with IPV6???????
Time restrictions (Parental functions) are not consistent. It's set to cut off WWW at 11PM every night on 1 specific machine and yet it chooses when to work?
For the price, I WANT IT ALL TO WORK!

Other Thoughts: I have faith in ASUS thus far, lets see if they fix the problems soon.

2 out of 5 eggsWon't connect to fibre service with no modem

Pros: Unfortunately, none. Could never connect the wan port to my Verizon FIOS fiber service. The unit ONLY recognized dhcp from modem device and their instructions always included this. You don't have to have a device on Verizon FIOS, you just need a router that understands the latest technology.

Cons: My Verizion FIOS (fibre optical) does not have a router or a modem. It has as fibre box and an ethernet cable that is provisioned to serve a public IP. The 2400 could not connect. Tried 2 different units. No good. Called Asus support and their solution at first was to upgrade firmware. When that did not work, they stopped offering solutions and just gave me a phone number. Instead, I exchanged the Asus for a Netgear R8000 and it connected in 1 second.

Manufacturer Response:

5 out of 5 eggsNothing bad to say about it...

Pros: So I got this unit to replace Apple AirPort Extreme 802.11n, as it was giving me issues with connectivity with my android devices (Kindle and Xperia Z2), and the range wasn't that great. Install was trivial; I created port-forwarding rules, enabled Trendmicro Ai options, and off it went. Range is great, connection is speedy, has been on for 2 days or so, no slowdows, restarts, and any connectivity issues. I connected all supported devices to 5Ghz channel, and the rest to 2.4. I wish I had something else to say, but it's simple, really. I haven't explored all the options yet, but I would definitely recommend this router, especially as a "wave 2" device.

Cons: MU-MIMO not yet enabled; earlier versions of firmware were reportedly buggy; I upgraded to the latest, no issues. The device is wide; definitely larger than any other router I had. Price! Almost $300 with taxes.

Other Thoughts: Overall, I'm happy with my purchase. Definitely solved my problem with poor range and spotty connection.

1 out of 5 eggsBugs in Access Point Mode

Pros: Fast, low latency, good range - when it works

Cons: Bugs when used in access point mode. Unit will "forget" a fixed IP assigned to it and pull a new one upon reboot/power cycle. 5GHz mode will lose connectivity to the default gateway reasonably frequently. 2.4GHz appears to be stable (other than the IP issue above)

5 out of 5 eggsSolid Router

Pros: Getting 126 Mbps down , 24Mbps Up on the second floor of my house which is around 4x faster then my Netgear WNDR3700. But this is contingent on your service provider speeds / Router. No dropped connections from devices. Overall solid product would highly recommend for a larger home.

Cons: Price.Price.Price

Not really a con just a concern router seems to run hot.

2 out of 5 eggsThey make awesome MB's

Pros: Very sleek. USB 3.0 for file sharing on network. You can detach the antennas to add stronger ones.

Cons: I had purchased this through ???? (sorry Newegg, got a better price break). I was using the netgear R4000 before I got this router. netgear did extremely well but my Roku had a "fair" connection on it for 5G in my 5000 sq foot home. so, I got the asus. and that was after about 2 weeks of research btwn the AC87R and the Netgear R8000. I got the 87R hooked it up and I went from fair to good with the wireless signal to my Roku. I was not impressed so I got some cheap stronger antennas to attach to the 87R and no results. What made me decide to return this item was because it would not recognize my Seagate 4Tbit drive housed in my Orico ext HDD enclosure. that was frustrating. I got it to recognize the drive twice for about 10 secs. after that, never again did it read the HDD. it read my 4Tbit no problem in the USB 2.0. but hey, I paid a high price for this thing and I want the USB 3.0 to recognize my drive. So then I decided to return it and I got the R8000. trust me, I build computers and I've always used asus. they seem to be the only MB's out there that are easy to work with (been building for over 10 yrs) so It was hard to admit that asus fail short with their router. so I got the R8000 and after a firmware update, low and behold, it recognizes my 4Tbit drive. I was impressed. PLUS I went from a "good" signal on my Roku to "EXCELLENT."

Other Thoughts: In conclusion the R8000 was and is a better experience for me compared to asus AC87R. the R8000 recognized my 4Tbit drive and, although I don't like the non-detachable antenna idea, it gave a much stronger signal than the asus. I heard that asus is coming out with their version of the 3200 as well. I hope it is better than the 87R.
