Some people say that ASUS TUF-AX3000 came out with the latest firmware with assassin mode, which can unlock 4x4mimo, then the total rate becomes AX5400.


Checking for firmware updates in the background indicates that there is a new version, but the online update fails.



I have no choice but to download it from the official website and install it offline. Latest version number


Check the 5G wireless parameters in the system record after the upgrade.


NSS3 and NSS4 are not available in TX.

It turns out there is an assassin mode option that has to be manually turned on to.


After the option is turned on and automatically restarted, check the 5G parameters again after the restart:.

NSS4 TX has it, 4T4R. Here are some random devices to verify it!

ASUS PCE-AC88 connects to TUF-AX3000’s 5G and then checks the rate in the router as follows.

PCE-AC88 速率

TX and RX rates are greater than 1400Mbps, it must be 4T4R. Take a speed test and see.

5G speed test result: 1050Mbps


From the data it is 4T4R. This is Wi-Fi 5, next verify Wi-Fi 6.

Take out the ASUS AX86U Design Wireless Relay TUF-AX3000 with 5G and the connection rate shown in the system is as follows.

AX86U 5G中继 速率


Both Tx and Rx are 3402.8Mbps, which is definitely 4T4R.

TUF-AX3000’s three Gigabit LAN port to AX86U a 2.5G network port to send packets, connected to the 2.5G network port of the network card is AOC107 chip 10 Gigabit network card. Successively measured several times upstream and downstream, but also adjusted different positions, the speed are countless did not reach 2GBps, usually in the 1600Mbps or so. Speed measurement chart is as follows.


3lan to ax86u 2.5g

The speed is disappointing, not as fast as 4x4mimo @160MHz should be. So, what is the speed as it should be? I don’t know.

I’m sure it’s 4T4R from the speed. I don’t care!

Next, let’s test the MU-MIMO support. The TUF-AX3000 is not eligible for this test because it is not 4T4R, but now it is, so let’s test it.

MU-MIMO in Wi-Fi 6 mode is off by default, so you have to enable this option to work: DL/UL OFDMA + MU -MIMO, the same as the Asus AX86U settings.



The results are in the last row of the following table.

MU-MIMO实测 02

The data shows that the TUF-AX3000 does not support MU-MIMO. i think so!

In the process of testing, because the data are repeatedly tested many times, after testing N times 5G signal disappeared, all computers lost the TUF-AX3000 wireless connection, the phone Xiaomi 10 also disconnected WIFi, check the 5G parameters, the channel is 0, also became automatic, I was fixed 44.

5G信道 0

Hard reboot TUF-AX3000 after 5G appeared, okay, it still works.

Summary: ASUS TUF-AX3000 brush firmware thing, open the assassin mode into 4T4R.

TUF-AX3000 in WIFI6 mode without MU-MIMO effect. Strictly speaking, does not support multiple 2x2mimo receiving devices.

Because there is no 1x1mimo 802.11ax wireless card in hand, maybe all the models in the table support multiple 1x1mimo WIFI6 receiving devices running in MU-MIMO mode. In reality, however, Wi-Fi 6 terminals are at least 2x2mimo now.
