The RT-BE88U, first announced in late March, is Asus’s third standalone Wi-Fi 7 router after the RT-BE96U and GT-BE98 Pro, and it’s a special one.

Unlike any other Wi-Fi 7 broadcasters I’ve seen, the RT-BE88U is unique in that it does not feature the 6GHz band. It’s a new type of cutting-edge hardware without having all the edges. While that might disappoint many enthusiasts, going dual-band has its perks.

Here’s the bottom line: If you can live without the 6GHz band, which might just be the way it is in certain parts of the world, the RT-BE88U is an excellent Wi-Fi 7 router with all you can look for in a single broadcaster. It has everything to justify the $399 price tag and then some.

On the other hand, if you need the 6GHz, the RT-BE96U is a better alternative.

Dong’s note: I first published this post on April 3, 2024, as a new piece and updated it to an in-depth review on June 12, 2024, after weekslong hands-on testing.

Asus RT-BE88U Wi-Fi 7 Router Box Content — Like previous models, the Asus RT-BE88U Wi-Fi 7 router comes with four detachable antennas, making it easy to use as a non-Wi-Fi router—the Wi-Fi functions can be turned off via its web user interface.

Asus RT-BE88U: A powerful first dual-band Wi-Fi 7 router

The first thing to note about the new RT-BE88U is its name. If it rings a bell, that’s because it’s the latest version of the RT-AX88U, which is the Wi-Fi 6 variant of the original RT-AC88U. For over a decade, this 88U lineup has been famous for two reasons:

Its typical design has become unapologetically representative of a “Wi-Fi router”—a flat rectangular box with four detachable external antennas sticking up from the back. At a glance, even the most novice users would know it has something to do with Wi-Fi.
It has the most generous built-in switch. In other words, it comes with the highest number of network ports a router can have, significantly more than the usual one WAN and four LANs.

The Asus RT-BE88U maintains those. In fact, it looks almost exactly the same as the RT-AX88U and is now even more generous on the port front, with 10 built-in ports in total.

Asus RT-BE88U Wi-Fi 7 Router Left Angle — The Asus RT-BE88U Wi-Fi 7 retains the traditional “I’m a Wi-Fi router!” design and now comes with the most network ports ever found in a home router, including six multi-Gigabit ports, one of which can work as the Gaming port, and four Gigabit ports.

Asus RT-BE88U Wi-Fi 7 Router Multi-Gig Ports — The Asus RT-BE88U Wi-Fi 7 retains the traditional “I’m a Wi-Fi router!” design and now comes with the most network ports ever found in a home router, including six multi-Gigabit ports, one of which can work as the Gaming port, and four Gigabit ports.

The second thing to note about the new router is that it is a bit less exciting—or maybe more exciting, depending on who you ask. As mentioned, the new router does not feature 6GHz. It’s not tri-band (or Quad-band) hardware like the rest of the Wi-Fi 7 crowd I’ve worked on. Instead, it remains dual-band like all previous models, with a 2.4GHz and a 5GHz band.

If you’re thinking, “What’s the point of Wi-Fi 7 without 6GHz?” you’re not alone. However, the truth is that the 6GHz band is not universally available worldwide, and where it is, it varies in width and portion. That’s to say, this band is complicated.

The adoption of the 6GHz band for Wi-Fi around the world

The 6GHz band has a total width of 1200MHz, ranging from 5.925GHz to 7.125GHz, and is divided into 59 channels of 20MHz each. These channels are grouped to create “sub-bands,” which also vary from one region to another.

In the U.S., the FCC has designated four sub-bands across the entire spectrum, including U-NII-5, U-UNII-6, UNII-7, and UNII-8, for Wi-Fi use, though portions of the band may be reserved for other applications. The E.U. Commission, on the other hand, allows only the U-NII-5 equivalent part of the frequency, or 480MHz in width, for Wi-Fi.

countries enabling wifi in 6ghz — The status of the 6GHz for Wi-Fi around the world

The use of the 6GHz frequency is complicated. Generally, Wi-Fi 6E needs a 160MHz channel to deliver the best performance, and Wi-Fi 7 requires double that, 320MHz. Due to spectrum availability and other reasons, real-world hardware tends to use narrower channels in most cases.

The table below shows its current adoption worldwide. The “Considering” potion is generally slated to be finalized by the end of January 2025.

Countries with 6GHz band for Wi-Fi 6E and Wi-Fi 7 as of late 2023.

Additionally, Wi-Fi 7 also has improvements in the 5GHz and 2.4GHz bands and will help make things better even when the 6GHz is not part of the equation. Since these two bands have been in use for Wi-Fi for almost two decades, it’s easy for hardware supporting them to fit anywhere.

In my testing, the new router proved to support Wi-Fi 7’s new 4K-QAM and featured dual-band Multi-Link Operation (MLO) to increase throughput and minimize latency—more in the performance section below.

Thanks to the lack of a third band, the new router maintains the traditional physical size used by previous models. The table below shows similarities and differences between variants of the 88U in Asus’s R.T. series.

Same design but now with more ports

The RT-BE88U looks identical to the RT-AX88U, including the color of its antennas.

There are minor differences, though: Its Asus logo badge is now a bit more fancy, and the new router also does away with the WPS and Wi-Fi buttons and the second USB 3.0 port on the front. In return, it has the most built-in network ports—all 10 of them, five of which are Multi-Gig, and one is an SFP+. In all, it has a combined total wired bandwidth of 34Gbps, the highest among its peers.

By the way, the RT-BE88U is Asus’s second with an SFP+ port after the RT-AX89X, which allows it to support high-end switches or certain Fiber-optic ONTs. Some might want to swap this port for a 2nd 10GBASE-T port, which can be arrived via an SFP+-to-10GBASE-T transceiver—I’d recommend the TP-Link TL-SM5310-T, which worked well in my trial.

The new router comes with four antennas that can rotate 360 degrees and open up to 90 degrees outward. Like the previous version, you can detach them if you don’t use the Wi-Fi function, which can be turned off via the web user interface.

So, if you still feel raw about the lack of the 6GHz band, you can use it as a non-Wi-Fi router and get a tri-band or quad-band Wi-Fi 7 access point to complete your setup. This is actually a good setup if you need to place the router in a far corner of the house or in the basement, where it’s not ideal to place your Wi-Fi broadcaster.

Asus RT-BE88U Web User Interface MLO — The Asus RT-BE88U features Wi-Fi 7’s MLO and, with AsusWRT 5.0, has Guest Network Pro, which enables users to create multiple virtual SSIDs to fit different scenarios, such as Guest Portal, Guest Network, LoT Network, and more. These additional SSIDs have in-depth customization and can be made available at the router or the rest of the system in an AiMesh setup when multiple hardware units are in use.

These additional SSIDs have in-depth customization and can be made available at the router or the rest of the system in an AiMesh setup when multiple hardware units are in use.

A familiar Asus AiMesh router

Despite the support for Wi-Fi 7 and the increased number of ports, the new RT-BE88U is slated to be a familiar router.

Specifically, running AsusWRT 5.0, it’ll be very similar to other Asus Wi-Fi 7 routers with Guest Network Pro and VLAN, on top of other goodies available to Asus’s entire RT series, including:

Robust web user interface with optional Asus Route mobile app and the ability to import setting backup files of other Asus routers. (In my trial, the RT-BE88U’s universal restore feature could handle backups from many, including the ExpertWiFi EBR63.)
AiMesh support.
Built-in Parental Controls and online protection (AiProtection) plus other traffic-related features.
USB-based features (cellular tethering, network storage, media streaming server, etc.)
The support for advanced VPN, including WireGuard and Instant Guard.
Tons of network/Wi-Fi settings, tools, and other features.

In fact, in terms of features, it’ll be very similar to the RT-BE96U, which shares the same AsusWRT 5.0 firmware. You can expect lots of practical applications from it, and all are free for life.

Asus RT-BE88U Web User Interface VPN — The Asus RT-BE88U supports all flavors of VPN and also has advanced VLAN for a robust network.

Like previous members of the 88U gang, the RT-BE88U also has gaming features built for gamers, making it an even more versatile router. It is part of the long list of Asus’s gaming routers in the table below.

The incomplete list of Asus’s gaming routers—the street prices might be different from the MSRP.
All of these routers include the standard set of Asus’s gaming features, including Mobile Game Mode, Open NAT, Gear Accelerator, and VPN Fusion.

You need a SFP+ to BASE-T adapter to use the Asus RT-BE88U with two 10GBASE-T devices — The Asus RT-BE88U is being tested. I used a TP-Link TL-SM5310-T to get a second 10GBASE-T port out of it, and it worked well.

Asus RT-BE88U: Excellent performance

I tested the RT-BE88U as a standalone router for a couple of weeks, and it performed excellently for the most part.

The router’s multi-Gigabit port proved to have among the fastest sustained wired performances, and its Wi-Fi delivered excellent coverage and sustained rates.

Clearly, without the 6GHz band, its wireless performance wasn’t as impressive as that of other Wi-Fi 7 routers, but it was more than fast enough for most homes’ needs, with Gig+ sustained speeds in many cases.

The router also had excellent range, similar to that of the RT-AX88U Pro or any other high-end dual-band router. It’s hard to put Wi-Fi coverage in numbers, but if you have a home of around 2500 ft² (232 m²) when placed at the center. But, the way Wi-Fi is, your mileage will vary.

The router also passed my 3-day stress test without disconnecting. It proved to be reliable. Despite having no internal fan, it remained pretty cool—it got slightly warm even during heavy operation.

Asus RT-BE88U Router Close Range Performance — The Asus RT-BE88U’s Wi-Fi performance when hosting clients of different Wi-Fi standards.

On the downside, the RT-BE88U’s network-attached storage (NAS) performance could use some improvement. When hosting a portable SSD, via Mulit-Gig wired connections, its read and write performance generally averaged below 200MB/s, as shown on the chart. That wasn’t exactly slow, but it clearly could be faster. That said, the router will pass for a mini NAS server for those with casual network storage needs.

Conclusion

The new RT-BE88U is an interesting router. As the first Wi-Fi 7 broadcaster without the 6GHz band, it likely will disappoint many users. However, if you don’t care for the new and complicated frequency, its wired networking extras make it worth the $399 retail cost. The fact that it has only two bands means it’s a lean piece of hardware, which can be a good thing.

There are many tri-band and quad-band routers out there, and they are good for all situations. However, within the world of dual-band hardware, the RT-BE88U is arguably the best router to date. And with Asus’s recent announcement, it’s not the only Wi-Fi 7 router sans 6GHz you’ll find down the line.

Dong, happy 4th! Long time reader, appreciate your reviews and attention to questions and comments.

1. I was looking for RT-BE88U and only found RT-BE7200 at my “best” buy store, is this the same device? All looks same but zero mention of RT-BE88U on packaging etc.

2. I have it setup, and max download speed using Azus QoS tool shows 4GB, but when I connect direct to my Google router I can get 8GB… is this normal or should these Asus routers achieve full speed coming from an 8GB router?

3. If I want more than 2.5GB to any devices downstream the Asus router do I need to make use of the SPF+ port, presumably to an SPF+ compatible switch?

Thanks much from a novice just trying to max out my speeds!

  Happy Fourth, Jeff!
  
  1. That happens a lot, like the case of the RT-AX58U vs RT-AX3000. They are essentially the same. The name change is to create a different SKU to help Best Buy cheat on its “price matching” promise. Generally, I’d go with the standard version, though, regardless of vendors. They tend to have better (firmware) support, etc..
  2. Don’t trust a router’s built-in speed test, they are generally accurate up to a certain threshold, often that’s Gigabit. More on speed testing here. As noted, a 10Gbps port generally deliver between 6.5Gbps to 8.5Gbps. Performance drops when you enable traffic-managing features, such as QoS.
  3. That or you have to use a transceiver as mentioned in the review. For your case the Zyxel XGS1250-12 or the Zyxel XS1930-12HP is a good option.

Hi Dong,
Providing that all of my devices only use up to WiFi6 (I mean, even the latest iPhones and Mac’s only support standards up to WiFi6e), should I stick with the AX88U Pro for the time being? Do I read it correctly, that the AX and AC protocols will be more efficient on the older model (considering I do not require more than two 2.5gbps LAN connections)?
- Dong Ngo

  Yes, Yoav.

I don’t like that dongknows.com doesn’t show the different mixes of router generations because a great example of “progress” without improvement is the BE88U vs AX88U Pro. If you look at the benchmark charts, neither will be on the other’s benchmarks. The description and summary talks about the BE88U being a great dual band router but when you compare the speeds compared to the AX88U Pro, you see the older does better in many scenarios since both are non-6ghz.

  You can put only so many items on a chart, Jeremy. Also if you want to compare apples to oranges you’ll need to do that yourself. Generally, a Wi-Fi broadcaster does better with clients of its standard than a broadcaster of a higher standard. Keep that in mind. There’s more to a router than the performance numbers.

Would have been perfect for me…..
but the SFP+ port is a deal breaker.
I need two “normal” 10g multi gig ports….
I’m therefore strongly considering the older ROG Rapture GT-AXE16000.
- Dong Ngo
  
  May 20, 2024 at 9:25 am
  
  Or the RT-BE96U or GT-BE98 Pro.

    May 20, 2024 at 12:20 pm
    
    hi
    yes the GT-BE98 (+pro) would be nice except for the price 🙂
    and on the RT-BE96U Asus has “limited” the Lan ports vs the GT-BE98 , so for me personally the GT-AXE16000 is a better option.
    
    One other alternative might also be a RT-BE88U and an sfp+ to rj-45 Transceiver (multi gig). but need to think a bit more about that……
    
    thanks for a great site

    Thank you for replying Dong,
    I noted that the 2.4GHz WIFI specs were all confirmed “up to 1376 Mbps” on the third line of the table entitled “ Asus RT-BE88U vs. RT-AX88U vs. RT-AC88U: Hardware specifications” but then, rather than leave the 5.0GHz WIFI specs line blank for the new router (as you would expect if the figure was unknown) on the 4th line … 1000 Mbps was entered (I processed that and thought it should read 10,000 Mbps?). Kindest regards, Vernon

Dong,

You seem to have stopped doing router WiFi bandwidth tests. That’s what I liked best about your reviews. The advertized bitrate on all routers is nonsense. I hope advertizers aren’t leaning on you to stop embarrassing them. I have been looking to you to find out how fast these routers really are.

Thanks,
Gene

First thing I wondered… How are they getting a 320 MHz Bandwidth in the 5 GHz Band? From what I understand, there are only three (3) 160 MHz Bandwidths available in the 5 GHz band, and they are not contiguous. Thus, it has to be doing aggregate channels. On top of that, the 5 GHz band is pretty congested, which means they may have issues trying to use a 160 MHz bandwidth. I know EERO uses a 240 MHz bandwidth in the 5 GHz band, but not sure how you could expect to get a 320 MHz bandwidth…
- Dong Ngo
  
  Apr 3, 2024 at 3:10 pm
  
  It was my typo. Fixed.
  
  And yes, realistically, you can only count on the 80MHz width.
