Key Features: Asus RT-88U


It is equipped with a powerful dual-core 1.4Ghz processor. It ensures faster-wired connection and USB data transfer. Its data transfer speed is up to 100Mb/s, whereas WAN-LAN throughput up to 1800Mbps.

Coverage & Range:

It supports AiRadar beamforming+ technology with four-transmit & four-receive antennas (4T4R). It improves WiFi range and stability of signals. While AiRadar focuses WiFi signal on our devices. It means, we get Faster, stronger, clearer WiFi on each connected device.

Home WiFi System:

The RT-88u comes with a very innovative feature called Asus AiMesh. With the feature, our router would be able to cover every part of our home.

It lets you create a whole-home WiFi network by using multiple Asus routers. In other words, it is flexible, straightforward, and powerful for mixing other models of Asus in one.


The bandwidth management of the router is top-of-the-line. You can connect multiple devices without any WiFi bandwidth issues. It is a complete entertaining router; whether you play HD games or videos, it won’t disappoint you.

Adaptive QoS:

With Quality of Service (QoS), we can prioritize activities, bandwidth, and gaming packets. It also lets us assign full bandwidth to any specific devices (It is convenient when you play in gamer solo mode).

However, it doesn’t allow dynamic QoS. It supports all the gaming consoles such as PlayStation 3, PlayStation 4, WiFi U, Xbox One, and even 3Ds.

Some Advanced Technologies: MU-MIMO, Beamforming, NitroQAM, and WTFast GPN.


The RT-AC88u is MU-MIMO supported. It becomes very frustrating when our WiFi network goes slow down. It all happens because of multiple connected devices at the same time.

Here the MU-MIMO technology takes place and ensures full-speed WiFi connection on every compatible device.

Asus introduced us a different version or next generation beamforming called AiRadar. So it becomes AiRadar beamforming, it focuses on WiFi signals to your connected devices.

In results, We get stronger, reliable, faster, and clearer WiFi with improved signal stability.

Game Accelerator:

It has in-built gaming accelerator inside, which improves ping time and variance (technical parameters). The GPN (Gamer Private Network) from WTFast allows router ‘route optimization’ for minimal packet loss and consistent-lower ping time.

Security: AiProtection, Parental Control, and Guest Network


When it comes to online gaming, security becomes very crucial. As you know, some heavy programs like anti-virus and 3rd party applications consume more CPU and Memory in order to protect your network.

It means, it slows down the router’s overall performance. Therefore, AiProtection allows you to turn off these applications while playing games.

Parental Control:

This function allows parents to control and limit the time for their kid’s devices. Plus, you can block particular websites or other contents that you don’t want your kids’ access.

In other words, you can allow specific websites’ access to your kids such as Wikipedia, school website, and other useful websites.

Guest Network:

Using this Guest network, you can create separate SSIDs or network. So you don’t have to provide your private network’s access to your guests and neighbors.

Moreover, The RT-AC88u router lets you create six SSIDs (three on 5Ghz band + three on the 2.4Ghz band).

Likes & Dislikes: RT-AC88u

I like:

  • It has 8 Gigabit Ethernet ports for multiple wired connections or extensive connectivity.
  • It has got built-in accelerator gaming chip inside from WTFast; it lets you enjoy smooth gameplay or multi-player streaming.
  • It is also packed with Link Aggregation feature; you can double the wired network speeds up to 2Gbps using link aggregation.
  • Four external AiRadar and beamforming supported antennas for better WiFi range.
  • We can create our own whole-home WiFi mesh network using AiMesh feature.
  • Initiative NitroQAM(1024-QAM) technology for seamless 4K UHD streaming and low-latency gaming.
  • Excellent Asus router app for controlling network from anywhere.

I don’t like:

  • A little bit pricey and gets hot sometimes.


At this price range, I would say the main competitor of RT-AC88U are: Linksys Wrt1900acs, Synology RT2600ac, Netgear R8000, Nighthawk X10, and Some other Asus models such as Asus ac5300 and Asus 86U.

After comparing these routers, I found the RT-AC88U better when gaming is concerned. Plus, other routers don’t come with 8 Gigabit Ethernet ports except for the x10.


The Asus RT-88u is a perfect choice for gaming as Asus made this router keeping gamers in mind. However, the router is a bit pricey. I’ve tried some other gaming routers like Linksys WRT1900Acs, Netgear X10, etc.

After comparing, I would say the Asus RT-AC88U is far better than WRT 1900Acs, whereas the x10 was better in terms of performance and range, however, gaming with the router was not that as good as RT-AC88U.

If you are a gamer, then you should consider this RT-AC88U. However, overall performance is not that as good as we expect from an expensive router.
