ASUS RT-AX68U is one of our favorite wireless routers with Wi-Fi 6 for several reasons: we like the way it looks, and we appreciate how it performs when using older standards like Wi-Fi 4 and Wi-Fi 5. Plenty of households and small businesses don’t have many modern devices and computers that work well with Wi-Fi 6. Most Wi-Fi 6 routers focus on providing the best performance when using the new standard, while ASUS RT-AX68U also delivers excellent performance when using the older standards. To top things off, the new Instant Guard mobile app allows you to connect to your home through VPN and protect your mobile devices while on the go. If you want a well-rounded Wi-Fi 6 router, ASUS RT-AX68U is an excellent choice that we recommend to everyone.

Unboxing the ASUS RT-AX68U AX2700 dual-band Wi-Fi 6 router

ASUS RT-AX68U comes in a black cardboard box with a picture of the device on the top. The packaging is similar to that of other ASUS Wi-Fi 6 routers, and it is easy to open. You find plenty of information about this model’s hardware and software specifications on all sides of the box.

Hardware specifications and design

RT-AX68U follows the design lines of one of ASUS’ most popular models: the venerable RT-AC68U, which is one of the company’s bestsellers. However, ASUS RT-AX68U is a lot thinner, weighs less, and has an updated design that's more modern and elegant than that of its predecessor. ASUS RT-AX68U has three nondetachable external antennas, and it provides support for Wi-Fi 6, WPA3 encryption, and 3x3 MU-MIMO wireless transmissions.

As you can see, the router is made of light plastic materials. The dominant color is black, and the router fits quite well in an elegant living room. The top margin is silver, and it includes a few discrete LEDs that signal the functioning status of the router and the Wi-Fi. They are tiny and nicely integrated into the top margin, so that they don’t bother users, not even during the night.

This router doesn't have any holes for mounting it on walls, and on the bottom, there are rubber feet that hold it in place on flat surfaces and stickers with information about your specific device.

ASUS RT-AX68U has a size of 10.19 x 2.66 x 7.33 inches or 25.8 x 6.75 x 18.6 cm, and it weighs 1.38 lbs or about 625 grams. On the back, you find the ports available on the router: the WAN port and four Ethernet ports, all working at 1 Gbps, one USB 2.0 port, and one USB 3.0 port. There’s also the Power jack, the WPS and Reset buttons, as well as the button for turning the router on and off.

The firmware on the ASUS RT-AX68U

The help documentation is easily accessible: when you move the mouse cursor over a setting that you do not understand, a question mark is shown. Click the question mark, and you see information explaining that setting. Unfortunately, the documentation has not been updated to include information about all the latest firmware features, so this trick does not work for everything. However, it works often enough to be useful.

To make this router even more appealing, ASUS RT-AX68U, alongside other Wi-Fi 6 models, offers support for Instant Guard - a new mobile app created by ASUS that allows you to connect to your home network through VPN from a public Wi-Fi. This way, you can benefit from an encrypted connection that is not easily snooped by others and from the AiProtection module bundled with ASUS RT-AX68U.

To verify the quality of the Wi-Fi broadcast by ASUS RT-AX68U, we took our laptop and moved it to a room that is separated by one wall from the router. We made a wireless transfer on it, using a specialized app that measured the average speed and the network transfer variability. On the 2.4 GHz band and the Wi-Fi 4 standard, the average speed was higher than that of other Wi-Fi 6 routers we tested in recent months. However, the variability of the wireless transfer was relatively high.

We switched to the 5 GHz band and the Wi-Fi 5 standard, and we were super pleased both with the average download speed that we measured and how stable the transfer was.

We switched to Wi-Fi 6 on the 5 GHz band, and the wireless data transfer was even stabler than on Wi-Fi 5, but the average speed was slightly lower.

We were satisfied with how ASUS RT-AX68U worked in our testing, especially when using the older standards: Wi-Fi 4 and Wi-Fi 5. If you have many older devices that don’t yet work well with Wi-Fi 6, you may prefer this router because of its reliable performance when using the older standards.
