Performance on a fast internet connection is not acceptable. OpenVPN client performance is also not acceptable. Sustained throughput of VPN client is < 30mbps which is not ok. Underpowered for any serious user.

I'm yet another victim of the notorious Virgin Media Superhub, which is mentioned a few times in the reviews of this product. Like the other victims, I too struggled with inconsistent download and browsing speeds and poor WiFi coverage from the Superhub and also struggled with Virgin Media themselves over the phone; "Yes, I've rebooted it and yes, I've checked the cables and no - it's definitely not a problem with two laptops, two smartphones, a tablet and a Chromecast in my house", but they refused to accept that it was down to a problem with the Superhub. I recently received a Synology DS216J NAS box as a birthday present and received a further kick in the teeth from the Superhub when I discovered that the transfer speeds between my laptop over WiFi to the NAS were trickling along at a pathetically slow 1.7Mb/s; this wasn't a great prospect when I was looking to transfer several gigabytes worth of files to it, so turned my efforts towards finding ways to resolve my networking woes. After a bit of googling, I discovered to my surprise that the Superhub can be wing-clipped and turned into a lowly modem through its configuration page (Something Virgin Media never thought of mentioning to me) and can subsequently have another router connected to it to take on the duties of pumping WiFi throughout the house, so it was with that thought that I decided to look for a sufficiently zippy router to connect to it. The problem when searching for things like routers is that there are simply thousands of ones available to buy and it can feel like wading through treacle trying to find a good one. Having gone through several of the things in my lifetime, I looked at reviews and settled on getting this Asus one after finding to my delight that it was nearly half-price on Amazon Prime. One of the buying factors was its dual 2.4 and 5GHz SSID's as I'd been having problems with only being able to choose one or the other with the (not so) Superhub, which was a problem as my wireless printer only supports 2.4GHz and was therefore causing everything else in the house to be dragged down to the lower throughput rate because of this, which wasn't much fun as it really seemed to adversely affect my laptop's AC-7260 WiFi card which is much happier when running on the 5GHz band. When the router arrived I relished the challenge of connecting it to the Superhub, the Synology NAS box and my various other bits of kit. I've often found routers in the past to be unhelpful, vague things which used acronyms for everything and be just about as clear as mud when it came to setting them up, but this is thankfully not the case with the Asus RT-AC51U. Once I'd stripped the superhub of its WiFi abilities and set it into it's modem-only mode, I connected everything up and fired my Asus router up. From there it was a simple case of opening the WiFi manager in Windows 10 on my laptop and opening a web browser, which promply brought me straight to the configuration page for the router and was displaying a set up wizard. Nice! Setting the Asus RT-AC51U up couldn't be any easier. Once you've set the admin username and password up it takes you straight to a page where you can set the names and passwords for the 2.5GHz and 5GHz SSID's. I decided to name them in a method which makes it clear which one is which and once I'd done that it took me straight to the main config page for the router - so no faffing around with IP addresses, which made for a pleasant change. When it comes to the configuration page for this router, this makes other routers ones look positively pathetic; it's well laid out, easy to read and absolutely packed with all sorts of features - many of which I wasn't expecting to find. I didn't even have to look at any instructions on how to change the default gateway IP or set a static IP for my Synology NAS as the user interface is wonderfully intuitive and simple to use. The only bit that caused me to scratch my head was when it came to setting up my wireless printer as I couldn't get my laptop to see it because it was connected to the 5GHz SSID. Having noticed that the router can act as a print server however, I connected the printer to the USB port on the router and checked the 'USB devices' section on the config page where lo and behold it had detected the printer make and model! Impressive. It still didn't explain how I was going to get my laptop to talk to the printer however, so it was with a squeak of delight that I discovered that the router has links to applications where I found a printer driver app that downloaded and correctly set up the printer on my laptop! By this point I was already singing the router's praises - never before have a seen such a well-featured, smart and intelligently designed bit of networking kit. Even more impressive is that fact that the transfer speeds to my NAS are now reaching 12mb/s (that's a 100% increase over the Superhub!) over WiFi and after conducting a broadband speed test I'm now getting the maximum download and upload speeds via my 75-meg connection. The signal is stronger throughout the house too and there's not been a single drop-out or problem with the connection speeds. This is without doubt the best router I've ever used and would absolutely recommend it without a second thought. Well done, Asus! >>> Update 13/03/2017 I've been using the router for nearly a month now and have not experienced any problems with it whatsoever. The WiFi connection from it has been steady, fast and 100% reliable for the whole time. I would have had to reset the Virgin Superhub at least twice by this point in order to keep it running properly. I remain really impressed with this router and would give it six stars if I could!

Il router e' arrivato con OS Asuswrt-Merlin, fantastico. Collegato in modalita' dualWan con chiavetta 4G Huawei E3372 , funziona perfettamente in failover. Anche le OpenVpn sono perfette. La VPN e' stata realizzata tra questo router ed un appliance pfSense. In precedenza era stato acquistato un altro router sempre Asus, RT-AC1200GPlus , che ho reso in quanto scarsissimo. Questo.... e' un altro pianeta...

I am really impressed with this router, this is my 5th router that I've set up in my house, and it blows away all prior! I upgraded from a 2007 D-Link DIR-655. The D-Link had been a great router, and I was loathed to replace it (I was a little bit emotionally attached to it, as at the time it was a great buy - basically the best router you could get, and it has logged in 6 years of great service!) but I was starting to get issues where streaming was choppy, and also that it required frequent reboots to get a decent hassle free streaming experience. I think the issue, was that the D-Link, while great in its time, was simply not designed to support the number of devices, and heavy demand placed on it circa. 2013, and still be stable! My requirements for a new router were a) strong signal strength b) reliability c) excellent streaming performance - i.e. something that I can basically forget about and will work really well on a consistent basis. I am a pretty loyal D-Link customer, but the reviews of their latest routers seemed pretty mediocre, so I decided to try out the ASUS. Net net, I have about 15 devices connected to this router - tablets, printers, streaming boxes, a hard drive, Nest, and multiple macs and PCs - and it works flawlessly with all of them. The setup experience was incredibly easy. My cable provider (AT&T UVERSE) provides a router already (2WIRE b/g), which was a little bit out of the norm to setup when I attached my old D-Link to it (I had to turn off DHCP and reconfigure the its Gateway IP - basically configure it as a wireless hub, not a router), so I was a little apprehensive about setting this one up. Impressively, the setup process just detected and configured correctly out of the gate. Setup process took about 20 minutes max. I configured the wireless network with exactly the same SSID and WPA2 password, so all my devices connected without requiring reconfiguring (apart from 1 or 2). I configured both 5Ghz and 2.4Ghz to use the SSID. Most of my devices are using the 2.4GHz automatically (better performance over longer range), it looks like the 5Ghz is being basically unused right now (and is defaulting to AC - though I don't have any AC devices). I might experiment with a separate SSID for the 5Ghz at some point to force devices to connect at 5Ghz, though I think it's probably unnecessary - most devices will figure out what frequency to connect at. In terms of reliability, I am about 2 weeks in. No reboots, incredibly reliable streaming. I've boosted the wireless signal strength from 80/200 to the max of 200/200 - though not sure if it was necessary to be honest. I'm getting a strong signal in every corner of the house (2000 sqft) whereas with the D-Link it was only a fair signal in the farthest distance from the router. I also attached a Lacie 1TB drive to the USB port on this router - and it detected and shared it instantly. Very cool. I've checked the router with Speedtest a few times over the last couple of weeks - and there has been no drop in speed (unlike the Dlink which would gradually slow down until rebooted). The router shipped with the .270 firmware, which has proved reliable. Note, as the other reviews have mentioned, this router runs HOT! If you are placing it on a surface such as wood etc., I would recommend putting multiple mats under it etc. to avoid causing an issue to the surface over an extended period of time. While this router is expensive, this one is worth the money and should provide years of great service.

El router funciona de maravilla. Tiene muchas opciones entre las que destacan las bandas se 2.4 y 5GHz, servidor multimedia y distribución de cuota de uso. Sí tienes una VPN puedes configurarlo para usarla y además de seguridad extra puedes eliminar restricciones geográficas. El Hardware es bueno. Lo único malo es que no se pueden reemplazar las antenas que tiene, pues son fijas. Co sus dos procesadores y 256 de RAM es suficiente para más de diez dispositivos entre teléfonos celulares y reproducción multimedia por el servidor DLNA y Netflix, así como una cámara de seguridad. Una muy buena compra sin duda.

El router en sí es de bajo nivel, tiene 5 puertos LAN y 1 WAN, 1 USB 2.0, lo compré simplemente para usarlo como punto de acceso y compartir un disco duro a través de su puerto USB, para esto cumple bien su cometido, además es posible instalarle un firmware de terceros como Padavan o OPENWRT.....Estoy contento porque cumple el cometido por el que lo he comprado. Perfecto.
