Asus RT-AX68U Review: An Entry-Level Wi-Fi 6 Router that Won’t Disappoint

Asus RT-AX68U
Asus RT-AX68U Dual-band AX2700 Wi-Fi 6 Router.

I find the Asus RT-AX68U AX2700 Dual-Band Wi-Fi 6 Router, officially announced today in the U.S., a bit of an oxymoron. It’s somewhat an entry-level Wi-Fi 6 router that comes out after Asus’s first Wi-Fi 6E machine, the GT-AXE11000. So it’s more like an exit-level Wi-Fi 6 broadcaster.

Jokes and semantics aside, this one is an excellent addition to the company’s impressive selection of Wi-Fi 6 solutions. In my testing, the new router proved to be fast, for its hardware specs, and reliable. And like most other Asus routers, it has a hard-to-beat set of features and network settings, including the latest version of AiMesh.

While not as powerful as its older siblings, at the sub-$200 suggested retail, the RT-AX68U is an excellent buy for those with a sub-Gigabit Internet and living in a small or medium home. Or you can use a few units to build an effective (wired) AiMesh system.

Asus RT-AX68U: Simple but effective

The RT-AX68U is a tad mundane, sharing the similarly traditional design of the Wi-Fi 5 counterpart, the RT-AC68U, that came out years ago. Out of the box, it has nothing of note, other than the shiny plastic body and three non-removable antennas, sticking up from its top.

The router also comes with a standard number of network ports — one Gigabit WAN and four Gigabit LANs. There’s no Multi-Gig port, but you can combine two LAN ports into a 2Gbps bonded connection. It also supports Dual-WAN and WAN Link Aggregation.

On the inside, though, its hardware is a bit muted, relatable to the similarly-priced RT-AX58U. But the two are quite different.

You’ll note that the RT-AX58U a 2×2 Wi-Fi 6 broadcaster, while the RT-AX68U is a 3×3 one. Yet the former is faster thanks to the support for the 160MHz channel width.

RT-AX68U: A standard Asus router

If you call the RT-AX68U a typical Asus router, you’re right on point. It shares the same web user interface (accessible locally via the default 192.168.50.1 IP address or router.asus.com), mobile app, and setup process, which is the same for any standard router.

On top of that, it has the core features and settings available in most Asus routers, including:

Universal setting restoration

During testing, I could restore a setting backup file of all Asus AiMesh routers (except for the RT-AX89X and the Blue Cave) on the RT-AX68U.

That said, if you’re upgrading your network from a Wi-Fi 5 router, this new Wi-Fi 6 machine will be a big time saver.

As a rule, though, it’s always a better idea to set up your router from scratch. Also, note that since routers are different, not all of the settings can be ported from one to another.

Among other things, the Asus RT-AX68U features WAN Link Aggregation

A robust full web interface with an excellent optional mobile app

Asus’s web user interface is one of my favorites. It’s intuitive and allows for in-depth customization. But the interface can be overwhelming for novice users. In that case, you can opt for the well-designed Asus mobile app. The app uses Dynamic DNS-based remote access — you won’t need a login account with Asus to use it.

AiProtection (a.k.a AiProtection Pro)

This feature includes a free-for-life real-time online Network Protection protection powered by Trend Micro and a decent Parental Control engine. It’s definitely an excellent and useful feature.

Network Protection is a friendly version of a home firewall application, similar to the Firewalla Blue + case. It won’t give you a lot of in-depth information, but it does keep your network safe, to a certain extent, of course.

The Parent Control is a bit underwhelming, but it gets the job done. And it can schedule Internet access for multiple devices.

Adaptive QoS

A quality of service engine that allows you to prioritize Internet traffic to support different applications and services — video conferencing, gaming, and so on.

This feature also includes Bandwidth Monitor if you want to know who uses the most Internet at all and Web History that shows the websites a client has visited.

The RT-AX68U’s QoS feature also includes a handy Internet Speed test if you want to find out how fast your broadband is.

Traffic Analyzer and A ton of USB-related features

Like other routers, the RT-AX68U comes with a Traffic Analyser feature, which includes traffic monitoring and statistical tools for those wanting to keep tabs on what’s been going on in their network.

What’s most valuable, though, is what you can do with the router’s USB ports. You see can use them to host portable drives, USB printers, or cellular dongles.

When hosting a storage device, the router has all the storagge-based features you can imagine — from data sharing (locally and over the Internet) to backup (including the support for Time Machine) to a personal cloud.

Featuring AiMesh 2.0, the Asus RT-AX68U support system-wide Guest network when working as the main router.

AiMesh 2.0-ready

Finally, like most other Asus routers, the RT-AX68U can work as part of a mesh system. I detailed that in this post on Asus’s AiMesh, but this new router features the latest version out of the box and can work well both as the main router or a node, with full benefits of AiMesh 2.0.

The Asus RT-AX68U works well in an AiMesh setup, preferable via wired backhaul.

In short, while not super impressive in Wi-Fi specs, the Asus RT-AX68U is very promising, both as a single router or as a member of a Wi-Fi system.

Asus RT-AX68U: Excellent performance

Without the support for the 160MHz channel width and a Multi-Gig port, the RT-AX68 doesn’t have everything it takes to deliver top Wi-Fi performance, according to the way I test routers. And that was the case in my testing.

Still, the router was quite impressive for its specs. It delivered!

Fast Wi-Fi throughputs

My 2×2 Wi-Fi 6 generally connected at 1.2Gbps of negotiated speed and registered the sustained real-world throughputs of between 770Mbps and 870Mbps from up to 40 feet (12 m) away. That’s about as fast as a Gigabit connection can give you.

The router did well with Wi-Fi clients, too. At a close range of some 10 feet (3 m), my 4×4 client managed to get some 700Mbps of real-world speed. And at 40 feet away, my 3×3 registered more than 660Mbps.

Asus RT AX68U Wi Fi 5 Performance Chart

On the 2.4GHz, the RT-AX68U did slightly above the average among Wi-Fi 6 routers, averaging between 217Mbps and 204Mbp, with the test client being up to 40 feet away.

In all, the RT-AX68U’s real-world speeds proved to be exactly that of a broadcaster of its specs. It’s generally fast enough to deliver a sub-Gigabit Internet connection in full.

Excellent coverage

I was able to get a hold of the RT-AX68U significantly before launch and used it for more than a week before publishing this review. During that time, I had no problem with it at all, both as a single or part of an AiMesh system. It proved to be a reliable Wi-Fi machine.

In terms of Wi-Fi range, it was about the same as that of the RT-AX82U, very good that is. It’s always hard to figure out the coverage precisely, but if you live in a home of 1800 ft2 (167 m2) without thick walls, the RT-AX68U will likely work out well.

Looking for a mesh system? Get your home wired with network cables, get a couple of units, and you’re all set.

Gigabit-class network storage performance

For a router without a Multi-Gig port, the RT-AX68U also did well in network-attached storage (NAS) performance.

Asus RT AX68U NAS Performance Chart

I tested it with the latest WD My Passport SSD and via a Gigabit wired connection it registered 107MB/s for writing and 112MB/s for reading, or about as fast as Gigabit can be in real life.

So get a decent portable drive, and you’ll have fun with this router’s USB applications galore. It’s a viable mini NAS server.

In a spending mood? (•)

Conclusion

The Asus RT-AX68U AX2700 Dual-Band router seems to be a bit late to the Wi-Fi 6 game. It has so many other older cousins that are collectively cooler, faster, and more exciting.

But more than making up for the late timing, it comes with everything you’d want from an Asus router, including excellent performance, a ton of features and most importantly, the full benefits of AiMesh 2.0.

If you’re looking for something that you can count on, without spending a ton of dough, this is an excellent router to take home. And it’ll prove to be a keeper.

  1. Hi, I was inspired by this post to upgrade and bought an RT-AX86U. But I’m seeing an issue with its LAN speed and wonder if you have any advice. I have 400 Mbps Xfinity through a Netgear CM1100 modem, and the internal speed test on the router shows over 400Mbs (yay). But speedtest.net on a PC connected to the LAN port is 200Mbs. The WiFi speed is great, in certain areas it is 300+. I don’t think it is my setup since the previous router (Archer C8) has lousy WiFi but does have full throughput to the PC speedtest. Asus support only said to enable jumbo frame, and that didn’t do anything. I even replaced the RT-AX86U with a second one but see the same thing. Any advice would be much appreciated. Thanks!

  2. Hey Dong, quick one for you.

    I currently have the AC66U as Repeater (on my 2nd floor) of the G3100 Verizon one and it work fine. The G3100 Verizon can choose automatically which channel to use (less busy one) but I usually have it set manually to one from 36 to 48, since those are the only that seem to work for the AC66u.

    The issue at hand is that the Verizon router refreshes every now and then and it starts doing again automatically and it usually chooses one of those 148-160 channels which are less busy, so of course the AC66U disconnects as it only supports up to 48.

    As far as I see I would come across the same with issue with the AX68U due to the channel support. AX3000 would seem to be my solution as it has a wide range support, as wide as the G3100. Would that statement be accurate?

    Thanks!

  3. Hi, I currently have an OK-performing Verizon Quantum Gateway (A-1100) router, for a 200 mbs FIOS connection. My house is about 1600 sq ft, two floors, with plaster & lath walls, so my 5ghz connectivity is kinda limited to the living room and the room next door. It’s an old house, and I can’t really start running wires through walls for a wired back-channel for a mesh system. If I stick to just one router, am I likely to see much of an improvement with the AX68U, or maybe the AX58U?

  4. Thanks for the great router reviews. One thing it would be nice to see is what versions of Samba these routers support when being used as a low cost USB NAS. The manufacturers are not helpful in this regard. I know you stated that most Asus Wifi 6 routers have SMBv2 capability in one of your prior reviews but it would be nice to see it verified in the review that SMBv2 or higher is active.

  5. Hi, I’ve been reading a bunch of reviews on here since I was in need of a new router. I’m moving in with some friends who have only been using the wireless from the provided ISP modem.
    We got a new place that’s 2 story 1200 square feet. All the bed rooms are upstairs and the connection for the modem is down stairs. We don’t really want to run ethernet cables upstairs so we’re switching to wireless for all our computers. We’re getting a 400 Mbps for the new place.

    So finally to get to my question. Would a wireless router like this do a good job of providing a good connection through a few walls or is it over kill for such a small place?
    Speed and reliability is pretty important since a few of us work from home or have to get on video calls frequently. Also having a good connection is good for online game as well.

  6. I have a question – not sure if this is the proper forum. I have an Asus RT-AX88U as my primary router. Looking for lower cost router to add as an AiMesh router. Is the AX68U better than the AX58U for that purpose with 2.4Ghz range in larger house being a high priority?

    Reply
  7. ax68u has the same cpu found on the ac86u. wasn’t a fan of that router and returned to stick with the ax58u. the tri-core routers seem more reliable.

  8. The problem with 160MHz is that you have to be next to the router, in order to get good sppeds. Otherwise, if you sit 10meters away, the speed drops exponentially. This is the reason I would choose a 3×3 80MHz over a 2×2 160MHz
