This Router Rocks!

Reviewed in the United States on October 16, 2017

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

I'm stingy with 5-star ratings, but this router is a quality product. It replaced an N600 Linksys EA3500 that was three years old and still doing OK because the Linksys can't (at this point, at least) be configured to use DD-WRT software. I plan to set up and install a Virtual Private Network, for security purposes and will use DD-WRT. This router CAN be configured to use DD-WRT, and I was amazed at how simple and powerful its GUI is. My Linksys EA3500 replaced an E2000 Linksys, and the setting up and configuring the ASUS was faster, easier, and smoother than any other time I've swapped routers. Bravo, ASUS! I'm a big fan of your motherboards, too; I'm running two of them right now.

01/01/2018 - Update: It died. I've been having intermittent connection problems and after I isolated the router as being at the root of the problems, I've done everything I could to make this router work properly; re-loaded firmware, upgraded firmware, re-loaded current firmware. I've wasted a good man-month and now it finally has died. It's time to replace this bad egg.

Performance is great until it's not. Price doesn't guarantee longevity. Warranty service SLOW

Reviewed in the United States on April 20, 2018

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

EDIT - WARRANTY WAS AWFUL.

I sent it back within warranty because it was dying. ASUS sent me back what must be a funny joke by a guy in their warranty department. They sent 2 antennas instead of 3, one of the two was completely broken.

They returned it with the wrong power cable. Not only the wrong cable- the wrong BRAND of cable.

The stand wasn't for this unit either.

What a disappointment!

Absolutely NEVER AGAIN with ASUS.

Original Review: It's a nice router, nice features, nice speed, nice coverage. You know it's an upgrade when things like Netflix stops buffering and you get full download/upload. I only gave it 3 stars because 1.5 years in, the inevitable router rot got to it, speeds slowed down, performance started to tank, and eventually it wouldn't stay connected to the internet for more than a few minutes at a time. Rebooting the router always fixes it for a few hours or sometimes a day, but you still have to do the ol' unplug-replug in the router routine that is basically a reality for all routers these days.

I even kept my router plugged into a power conditioner/battery backup to prevent any dirty power from damaging the router. Still died.

For this price, I expect this router to outlast a sub-$100 router. I paid extra for the quality I expect from ASUS. If these routers are bound to die within 1.5 years, I might as well save half the price and get an economy router.

I've sent it back for warranty, but here's the rub- nobody can go a month without internet. They make you pay for your own shipping and then they hold it indefinitely with a repair status of "Material/spare part(s) shortage. Item is on order and/or incoming."

I don't know if or when I'll get it back, and I hope the issue would be fixed if they did. But if they return a refurb, I can only imagine it's got months before the issue inevitably creeps back up. Since it's been a few weeks I went ahead and just bought a different router anyhow, because it's 2018 and nobody got time for that down time. So if they do send it back, I guess I'll use it as a backup.

In hindsight, I wish I hadn't bought an Asus product.

Reviewed in the United States on August 25, 2020

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

This is not a bad wifi router, and I've had no problems with it. But I'm a little salty about the fact that Asus released an updated version of this router shortly after I purchased this one in 2016, and it comes with the aiMesh feature - this one does not. Also, it's nearly $40 cheaper than the one I bought, which is super-annoying.

But what's REALLY irritating is that they did not change the model number for the newer device! So when you search "RT-A66U" or "AC1750", you wind up with lots of results for the RT-A66U-B1 version, which DOES have aiMesh. So I live in this world where any search results for my router's model number are gonna be polluted with information for the NEWER model, and not my own. Very infuriating, and I'll probably steer clear of Asus in the future, simply because of this.

So again:

- They released a newer version, but kept the same model number
- It's $40 cheaper than what I paid for this one, and it has more/better features
- And now I can't find accurate info about the device i DO have.

That's a bunch of bullcrap, if you ask me.

IF IT WORKS, it might be great. If it's broken like mine, you're stuck with a paperweight they won't support.

Reviewed in the United States on August 15, 2015

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

Obviously broken. Wireless speed drops down to as low as 1.5 Mbps while sitting right in front of it. Constantly dropping connections. Streaming video is horrifically difficult, if it works at all.

I'd be willing to accept this and RMA it IF I COULD RMA IT. Contacting ASUS is unbelievably difficult. They state they will get back to support tickets within 48 hours. It's been six days with nothing. Message in support forums - zero responses after eight days. I called four times. First, getting them to understand anything spelled is unbelievable. I repeat myself three times EVERY TIME they want my name, phone number, or case number. Over the four calls, I was hung up on after rep tried to look up ticket, told I had to call a different number, hung up on immediately, and finally told "I can't hear you, call back another day" repeatedly until the rep finally hang up on me (rep was trying to avoid her hanging up on me so I couldn't leave feedback after call). As if that feedback is actually acted on...

So while I'll keep trying to get this piece of crap sent back, ASUS avoids its customers like the plague. Easier than supporting defective products, I suppose. I honestly thought they were a quality company before this, but I'm completely done with them forever simply due to their complete lack of support. Worst I've ever seen.

Initial setup can be rocky, after this smooth sailing!

Reviewed in the United Kingdom on December 27, 2018

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

Purchased this to replace a 5 year old failing TP-Link router. It came with the usual peripherals alongside the main unit (AC-adapter, CD etc).

I'll cover the only real negative aspect about this router first - The setup process.
Instead of being able to pick a dive straight in option or a more 'guided tour' ; there's only the guided tour method. This may have been something to do with the outdated firmware however I've not attempted to reset from factory since (I mean it's a router, when it's working - it's working!). Generally I don't have an issue with this however it wasn't helped by the fact the setup process seemed to have some performance issues; it would lock up and require a reboot to reset the process again. I'm putting this generally down to probably too much first-time setup going on in the background as these issues didn't persist once the actual router was up and running.

The only word of warning after this point would be to perform a router firmware update immediately - the router I was shipped was running a vulnerable version of the firmware. Thankfully Asus make this easy enough and you can do this from within the router; as opposed to having to navigate to the website and flash it yourself. The router is also capable of notifying you when you log in if it detects there's a newer update which is also a fairly nice touch.

Beyond that initial negative step - everything else runs swimmingly and does exactly what you'd expect it to, from the bigger things to the smaller touches. If you're wanting something that affords you the ability to be flexible without having to look towards more enterprisey-options then this actually does the job incredibly well. You get typical staples such as QoS / MAC address filtering; as well as nice additions such as IPv6 support, mesh networking and even wake on LAN!

For me one of the bigger wins has to be how muted the LEDs are in brightness - they don't illuminate the entire room when it's darker, yet at a glance it's still clear exactly what's going on.

Fundamentally for what you're paying - this is a solid piece of kit and well worth it. You're probably not going to find a more feature-full router at this price-point, even if the setup can take a few attempts to get right!

Very Good but set up instructions needed lots of internet searches

Reviewed in the United Kingdom on July 7, 2019

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

Now that I have had my Asus for a month I feel it is time to write a review. I am not a technology wizard and I honestly struggled with the instruction manual. I definitely had to search on line 4 or more times to discover how to change some of my laptop settings to help the Asus to work reliably.
For example disable proxy setting... IP/TCP setting...change to automatic...on first read it was just like what????
I spent ages trying to open the software in the program box but it was doing nothing. I had open a screen that looked identical in my web browser I assumed wouldn't work until fully set up.
Once I did exactly what it said the 1st installation went well. Make sure you note down your user names and passwords for the router as you will almost certainly need them again and wish you had made a note.
It seemed fine but connection to the internet was not reliable. I started again and finally worked out that I hadn't made the correct changes to my lap top network settings for it to function properly.
Having set it up it is now super reliable and providing an excellent solution to my daily nightmare of my virgin media hub 3.0 failing to deliver a stable internet connection when signal was not a problem. The hub is now in modem mode and is much happier. Apparently the chips are not up to the job and need regular resting and resetting and unplugging. That got utterly tiresome and Virgin Media would not admit the hub 3.0 is flawed and were charging a fortune for solutions that may not have helped. Plus they raised my bill by 8% thanks so much I was paying more for an awful service. I was a hairs bredth from swapping provider when I gave the Asus a go. At least I get the speed I pay for now.

Excellent AiMesh node

Reviewed in the United Kingdom on July 19, 2020

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

I purchased the router to act as an AiMesh node, alongside my ASUS RT-AC86U. Setup was easy - firstly connected as router and updated firmware. Then did a factory reset and setup as an AiMesh node (following the ASUS guide). No issues at all.

Positioned at the opposite end of the house to my current router, all my devices switch seemlessly - this includes iPhones/iPads, Windows laptops, a MacBook Pro, android phones, etc. I now get a strong Wi-Fi signal throughout my house and even a reasonable signal at the bottom of my garden.

I have the nodes connected via Ethernet - I’ve not tested LAN bandwidth, but I can get around 390Mbps internet speed from the node (Virgin 350 broadband).

Interestingly, although the router doesn’t “natively” support 2.4/5GHz switching automatically (same SSID) as the 86U does, it does do this when acting as a node.

Overall very impressed and has greatly improved Wi-Fi at the far end of house. Well worth the money!

Disappointing router

Reviewed in the United Kingdom on March 3, 2019

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

I bought the AC66U_B1 to use with my rubbish Superhub 2ac that kept dropping the wi-fi and forgetting my 20+ devices. For the price, I expected this Asus to be easy to set up and work flawlessly. WRONG!
Initially, it looked like setting up was going ok, but the web interface is quite clunky and the list of connected devices was all over the place. Some it just refused to find and others it just dropped after finding. I spent the best part of 4 hours trying everything I knew and I've done this sort of stuff for years, yet it was futile. I tried the phone app and that was just as bad. Eventually, I gave up and put the superhub back how it was.
I am very disappointed with this router and expected much better performance. My respect for Asus has been tarnished by this product and it is currently in a box, ready to return to Amazon.

An excellent router, but for a firmware upate problem (now solved)

Reviewed in the United Kingdom on June 14, 2019

Size: NewStyle: RT-AC66U (AC1750)Verified Purchase

Despite the firmware updating problem, I can highly recommend this ASUS RT-AC66U B1 (AC1750) router. It performs well with a strong wifi signal.

This is for the benefit of ASUS router owners who may experience a problem with updating their router’s firmware.
As the owner of a very reliable ASUS RT-N66U, I was not expecting any problems with my new RT-AC66U B1 (AC 1750).
Basically my router was fine except for its inability to do a firmware upgrade via the standard process, i.e. clicking on either Agree during Setup or later by clicking on Firmware Upgrade.
To get round the problem, I visited ASUS Support UK.
I entered the product number, RT-AC66U B1 in the search box, clicked on the product icon and then selected BIOS and Firmware.
I then downloaded the latest ASUS RT-AC66U B1 Firmware version (3.0.0.4.384.45717 zip file, dated 2019/5/13).

NB Whether you use Windows or Linux, you MUST first unzip (extract) this zip file in order to extract the required TRX file. Trying to upload the zip file will NOT work!
This TRX file can then be uploaded by opening the ASUS 192.168.1.1 router configuration and selecting Advanced Settings >Administration > Firmware Upgrade.
At the bottom of the page, under AiMesh router (this is also okay for a standalone WRT router where no additional AiMesh routers are being used), click on Upload next to Manual Firmware Update and then browse for the appropriate TRX file which you previously extracted/unzipped. Locate the TRX file and then click on Upload or Open.

Once 100% Complete is displayed, you will be asked to reboot the router manually.
Do NOT close the browser!
Simply go to the router and press the black button at the rear (next to power connection) ONCE. Then press it ONCE again. Then WAIT!!

Do nothing. Leave the system to reboot and the Router Login page will be displayed.
Login again and check that the update has been done (new firmware number shown).
Logout.

NB It is very important to change both the router login Username and Password from admin/admin to something far more secure.
Also, if things get really messy, you may need to put the router back to factory defaults by going to Administration > Restore/Save/Upload Setting > Factory Default > Restore.
