If you require extremely high transfer rates, the Asus RT-AX88U will not fall short of your expectations, despite the fact that it is an extreme overkill router. Due to the fact that this is one of the first Wi-Fi 6 (802.11ax) routers to be released onto the market.
There are not yet a great number of clients that are able to benefit from it. Everything is backwards compatible, which means that this router continues to give outstanding performance on both the 2.4GHz and 5GHz bands to devices that are already in use.

Asus RT-AX88U review: Design and features

The RT-AX88U is well-made and doesn’t have as many flashy features as the ROG Rapture GT-AX11000, which is made for gamers. Only the cutouts in the four antennas that are lined with gold show that this router is special.
But it works well and is pretty upscale. There are eight Gigabit Ethernet ports, and while the AX88U doesn’t have a 2.5GbE socket like the ROG Rapture, the first two ports do support 802.3ad link aggregation. You can also use LAN port 4 and the WAN port together to get a 2Gbits/sec internet connection, which not many of us will be able to use. You can buy this router from its official website.
Asus RT-AX88U review: Connectivity
Because it is a dual-band AX6000 router, the Asus RT-AX88U is capable of broadcasting simultaneous 2.4GHz and 5GHz Wi-Fi networks. The data transmission rate of the 2.4GHz network can reach up to 1,148 Mbps.
While the data transmission rate of the 5GHz network can reach up to 4804 Mbps. The 5GHz network is capable of handling a throughput that is somewhat lower than 4333Mbps when it is operating in compatibility mode according to the older 802.11ac specification.
Asus RT-AX88U review: Performance

In our tests, the latest version of Wi-Fi, known as 80211ax (also known as Wi-Fi 6), demonstrated significant improvements to 5 GHz throughput as well as gameplay in environments where the network was congested. In spite of the fact that its current street price of $346 places it in the high end category.
The RT-AX88U certainly justifies its position there given how well it performs. To say that we are impressed with what we have seen of 802.11ax thus far would be an understatement. The Asus RT-AX88U is an excellent option to take into consideration if and when you decide it is time to upgrade your router.
Asus RT-AX88U review: Price and competition
In our tests, the next generation of Wi-Fi, called 80211ax (Wi-Fi 6), clearly improves 5 GHz throughput and gaming in a networked environment that is already full. The RT-AX88U is in the high end category because it costs $346 on the street, but it deserves to be there because it works so well.
Final Words
Even if you don’t have many Wi-Fi 6 devices in your home yet, the Asus RT-AX88U is a great Wi-Fi 6 router and a great way to make sure your home network is ready for the future. Even though Wi-Fi 6 has faster data transfer rates than Wi-Fi 5, you shouldn’t have to worry as much about that once most of your devices switch from 802.11ac to 802.11ax. You can save some money by using a Wi-Fi 5 router, but if Wi-Fi 6 devices become more common, you may want to upgrade again.
