Asus RT-AC88U Wireless AC3100 Router

Asus releases new wireless ac3100 router – RT-AC88U dual band with beamforming, MU-MIMO and link aggregation, with powerful Broadcom NitroQAMTM technology to boost the wifi speeds.

Why AC3100?

Surely we would ask, why wireless AC3100 router? Hasn’t been there already a wireless AC3200 router? At a first glance they are not much different, just a speed difference up to 100Mbps when in fact they are greatly different. Asus AC3200 is a wireless three-band router, like other wireless AC3200 routers that have been around for a while such as Netgear Nighthawk X6, or in Linksys EA9200, and also D-link DIR890L. They are all three-band wireless routers. But Asus RT-AC88U is a dual band wireless AC3100 router.


Broadcom NitroQAMTM technology

With only two bands the router can deliver speeds up to 3100 Mbps just 100Mbps speed difference with other existing three band routers (3200Mbps) , what is the speed if it is a three band router? That’s what we see now in Asus RT-AC5300 router with speeds of up to 5300Mbps. So where is the main difference? The difference is the uses of Broadcom NitroQAMTM technology that can boost 5GHz data throughput up to 2167Mbps and at 2.4GHz band it boost speeds of up to 1000Mbps. So that’s why in three band wireless router, with Broadcom NitroQAMTM technology it can deliver total speeds of up to 5300Mbps (2x 5GHz 2167Mbps plus 1x 2.4GHz 1000Mbps).

In two band version, with Broadcom NitroQAMTM technology Asus AC88U can deliver speeds of up to 3100Mbps.

What this router does

This is the new era of Gigabit speeds in wifi, it feels like it were just couple of days ago when 5G wifi was introduced in wireless router with the speeds of up to 1750Mbps. And today you can feel the fast lane of three band wireless router with speeds of up to 5300Mbps. And the dual band version you can find here in Asus RT-AC88U that delivers total bandwidth of up to 3100Mbps, one 5GHz band with speeds up to 2167Mbps and one 2.4GHz band with speeds up to 2.4GHz band.

The other advanced feature is the capability of link aggregation that can deliver double wired speeds of up to 2Gbps by combining two Gigabit Ethernet Ports. It is like a network teaming feature in Windows server 2012.

Port aggregation

Actually Asus also releases another similar router, the Asus RT-AC3100 dual band router. What is the actual difference is the number of Ethernet LAN ports is only 4 compared to 8 ports on RT-AC88U. with twice the total number of Ethernet LAN ports you can add more devices to the router with wired Gigabit LAN connections. With more heavy duty devices connect to LAN ports of the router, the more bandwidth demand. When all those wired connection access files from the NAS intensively, you need to install high speed NAS. Thanks to link aggregation feature in Asus AC88U. With link aggregation you can add NAS which has link aggregation feature to get the maximum data rate throughput of up to 2Gbps.

Have a look at the following table that shows you various models of wireless routers which have unusual Ethernet Switch feature regarding port numbers.

Table 1 LAN Ports comparison
  Ethernet LAN Ports Link aggregation
Asus RT-AC88U 8x Gigabit LAN Ports Yes
Asus RT-AC3100 4x Gigabit LAN Ports Yes
Asus RT-AC3200 4x Gigabit LAN Ports No
Asus RT-AC5300 4x Gigabit LAN Ports Yes
Netgear Nighthawk X8 6x Gigabit LAN Ports Yes



Asus RT-AC88U is powered by 1.4GHz dual core processor, the fastest router processor so far. Who else uses this 1.4GHz dual core processor? Have a look at the following table that shows you comparison of high end wireless routers regarding processor used.

Table 2 Processor comparison
Router Processor
Asus RT-AC88U 1.4 GHz dual core processor
D-link DIR-890L AC3200 router 1.0 GHz dual core processor
Netgear R8500 Nighthawk X8 1.4 GHz dual core processor
Netgear R8000 Nighthawk X6 1.0 GHz dual core processor
Linksys AC3200 router 1.0 GHz dual core processor
TP-link AC3200 router 1.0 GHz dual core processor
TP-link AC2600 router 1.4 GHz dual core processor


You can see that the three band version of routers come with only 1GHz dual core processor, such as Tp-link Archer C3200 with 1GHz dual core processor while the TP-link AC2600 router come with higher processor.


The other beneficial feature is the inclusion of Security and privacy protection by AirProtection, so you can free off your local computer ‘Windows defender’ (in Windows 8 and Windows 10) feature that can exhaust your computer resources. By disabling your local security defender, you don’t need to worry about the computer security because the security task is taken over by router.

You can play heavy duty online gaming that generally takes high degree computer resources, now you can free-up the resources by disabling the Security defender safely. In addition of WTFast game accelerator you can boost your online gaming in higher degree, faster than router without the accelerator.


Asus RT-AC88U is ideal for heavy duty environment, large home with multiple devices either wired or wired connection, streaming 4K video and online gaming. The fastest 5GHz band up to 2167Mbps is ideal for those heavy duty tasks.
