2 out of 5 eggs2.4ghz wireless band unusable

Pros: High-quality ASUS construction
Nice admin panel
Easy setup or highly tweakable--whichever you prefer
Excellent wired router
Long range wireless

Cons: Continuous frequent dropouts at 2.4ghz band
Non-existent customer support

Other Thoughts: I replaced a dead router with an ac56u a week ago. It has the latest firmware (version, released 9/23/2014, but I also tried two other versions) and I made very few changes in the settings. It has the same sysid for both bands.

My wife began complaining of poor internet performance on her laptop almost immediately. I put Ping Plotter on three computers. One is on the wired connection; two are wireless. Reviewing the graph after 12 hours, both the wireless-connected PCs (the second one is an HTPC fairly close to the router) showed many packet losses. The wired connection was rock-solid.

(Having said that, the second computer is connected to a bridge that can work on both bands--so these might actually have been dropouts on the 5ghz band! But they were dropouts nevertheless and occurring every few minutes.)

It was only then that I started to see in other reviews that this is a common problem with this router, one for which ASUS has yet to provide an answer. It seems to be related to the 2.4ghz band, which is where the drop-outs primarily seem to occur. I have about 15 internet-connected thingys in my house, so perhaps that's why people like me notice the problem. I suppose if you have only a 5ghz laptop or two, you'd never notice.

For me, it doesn't matter how many other good features the router has, this serious flaw is a deal breaker and renders it unusable. Like having a really nice car with three tires, it just doesn't matter. This is the first router I've experienced with this problem.

At any rate, after trying all of the recommendations from ASUS and others that I found on the net (ASUS never actually responded to my tech support ticket and never responded to my email), I took the router back to the store and got the NETGEAR R6250 instead. I'm only 12 or so hours with it onlline, but so far the performance seems flawless.

If this frequently-experienced problem is something that could be fixed by settings-tweaking, then there is no excuse for ASUS not having a FAQ by this time to walk you through the solution instead of asking you to wait for never-returned emails. It makes me suspect there is no solution.

Shame. I think ASUS products are typically outstanding and it has become a no-brainer brand for me but it looks like this router wasn't quite ready for prime time.

5 out of 5 eggsSleek and Fast

Pros: After purchasing new modem and internet package we determined our older router to be the bottleneck. Purchased this router on a great sale day after some research and patience and I don't regret it. Reaches all corners of our place with no discernible deadzones. Also seems to handle many units pretty effectively (does lose some speed with 6 going at once but what do you expect?)

Sleek design! Smaller then my mental image and looks good on the desk.

ASUSwrt is pretty user friendly and configurable. Testing it's storage capabilities soon here

Cons: CHECK FOR FIRMWARE UPDATE- the model that was shipped to me contained outdated firmware (I believe before the AIcloud fix). Can't knock an egg as it's a pretty recent update.

4 out of 5 eggsKind of does the job

Pros: Works great 90% of the time

Sleek, slimline, attractive design

Cons: Slow and drops connections 10% of the time.

5GHZ range not that great

Internal antennas

Other Thoughts: Sometimes I experience connectivity and speed issues. Whenever this happens I power cycle the router (not the modem) and the issues disappear. This could potentially be things further down the line.

5 out of 5 eggsNo Problems for me :)

Pros: looks awesome, nice design, small footprint doesnt take a lot of room on your desk.
love the wireless ac
comes with everything you need
easy to setup

Cons: NONE!

Other Thoughts: I guess I'm one of the lucky ones that hasn't had any problems with this router. I don't lose signal , probably because most of my devices I use, use the 5GHz band a pose to the 2.4GHZ, but even my iPod doesn't lose any signal.

1 out of 5 eggsVery disappointed!

Pros: Easy setup and configuration

Cons: Dropped connections like crazy, range is not good, performance is worse than a 4yr-old router.

Other Thoughts: In short, you should totally skip this product. This router would give you more troubles than you would expect. And NewEgg charged you for shipping it back. Would not recommend the product and would not purchase from NewEgg for a long long time.

5 out of 5 eggsGreat router

Pros: I was upgrading one of the higher end TP-Link routers because I was having some issues with packet buffering on the gateway. Brought it home (purchased from MC) and connected it to my laptop and ran through the setup and had it up and running and all my devices connected to it in 5 minutes.

the GUI, although different than standard GUIs for consumer routers, is intuitive and feature rich. I am still running on OEM firmware and I have not run into any limitations on it yet.

The network tools included on the router (QoS, Auto Channel, 2.4/5GHz bands) make this a very reliable router and I have found that my router is no longer the bottleneck.

The build quality is nice, and USB 3.0 for NAS is a plus. Havn't played with the AiCloud feature much yet, but it looks promising enough.

Signal is excellent (single story home) throughout my home. Have not had any dropoffs in the 3 weeks I have had the router.

Highly recommend this router for anyone looking to upgrade from a low/mid-level consumer router.

Cons: Fixed stand, unable to mount on wall.

1 out of 5 eggsWi-Fi dropouts galore

Pros: It's absolutely beautiful. Has a ton of features, some valuable, some not. Cheap for what it is. Somehow won lots of awards and 'best router of today'. Frequent firmware upgrades.

Cons: Constant Wi-Fi drop outs indicative of rushed technology in the home router industry. Meh support that paralleled my experience working in a call center where you bean your poor customers over the head with dumb questions hoping they'll give up and frustratedly exchange it. I was sold on the look of the thing but, like the 6 of the 9 other sub 120 dollar routers I've demoed, dropouts are rampant. I have managed roughly 3 minutes without 3 sec latency spikes followed by WAN outage for 4 minutes or until I reboot it. Newest current firmware and factory reset did nothing. Setup via wizard or otherwise. Result is the same. Unplugged it and went back to my draft N Belkin that's currently bulletproof but slow. Haven't had it drop in 2 years of faithful service. So much for 'upgrading'. Judging by other people's reviews ASUS will try to make me exchange it for a new equally broken unit with the same fallacies.

Other Thoughts: Time Warner cable black surfboard modem. 11 megabit or so service.

Only buy this if you want to get your undies in a wad and unplug it, waiting on ASUS to send out new firmwares. Just wait for the price to go down and be patient. I can promise your current router will be just fine for another year till they fix this one. Or it will continue to plummet in price because they never get it working right. As a long time ASUS user... I say that I expect such antics from companies like netgear but ASUS knows better.

5 out of 5 eggsRT-AC56U w/ firmware

Pros: Initial setup was a breeze, and default settings were pretty good.

This latest version of firmware is 47 days old now, and seems very stable with no reboots required.

Several different new and old Wi-Fi adapters, laptops and smartphones are all getting great service in a very noisy Wi-Fi congested condo building.

One example: An EDIMAX EW-7811UTC #N82E16833315132 AC600 adapter gets it's maximum rated 5 GHz connection speed of 433 Mbps on a Win 7 machine in the next room; fast and sweet.

But, the crown jewel: my neighbor on a Win 8.1 desktop with an old TP-Link WN722N #N82E16833704045 2.4 GHz adapter is getting reliable 65 Mbps connections, consistent service and 4 out of 5 bars in the OS. That machine is ~120' away through many metal stud walls and obstructions and getting stepped on by a bunch of neighbors! Nice.

Cons: Price.

I haven't tried any third party firmware -- the only thing I need and miss is better charting of remote signal quality, so it hasn't been necessary yet.

The router is always warm, never cool to the touch; but never really hot either.

Other Thoughts: To get good 2.4 GHz long range service: 1) I set the bandwidth to 20 MHz (upper limit 144 Gbps); and 2) I traded off USB 3.0 maximum throughput in favor of 2.4 GHz performance (Advanced Settings, Wireless, Professional, Reducing USB 3.0 interference -> ENABLE). While 2.4 GHz speed is reduced by the narrow bandwidth, and USB 3.0 performance takes a hit, the 2.4 GHz Wi-Fi works beautifully!

This is a very nice product. If the price works for you, you'll love the router.
