I have the same log section as Funnyland has, but my WiFi is working.
Maybe your WiFi is just misconfigured. I haven't tested it myself, but here is a link that explains how to regenerate the WiFi configuration:

The wifi doesn't start anymore even with the original Asus firmware. Which is normally always active after a reset

And when flashing to RC1 and RC 3 it went without any problems

Apparently calibration data got missing on flash somehow, maybe you overwrote it with something else?

I have no idea but I don't know how to fix it

I've uploaded a backup of both factory partitions, Factory and Factory2 here from my ax4200tuf:

These instructions might be of help to get them flashed.

Here is a full ubi0 backup incase you need it:


Hi, I ordered this router yesterday and I have some questions:
1- Can you increase the Wi-Fi power on the original firmware?
2- Is it possible to install OpenWRT with a graphical interface on it without disassembling the router?
3- Finally, can you revert to the original firmware after installing OpenWRT without soldering, etc.?

Ask Asus.

If you'd have read the thread, you'd have known it's a no.

Since already have it set up for installing, it doesn't really matter if you also needed for uninstalling.


just wanted to say thank you System is running again


Hello, I just filled the TUF-AX4200's Wiki Page.
In the past, someone created two other blank pages for the same model, I found no way to get them deleted.

tuf ax4200, ax4200.

I used the already existing hwdata page, but the name does not match the wiki page: asus_ax4200 - perhaps it can be renamed to tuf-ax4200 ?

This is my first wiki page, and I'm not sure about the tags and the hwdata, I'd appreciate it if someone could look over it.


Hi everyone. Among those who have flashed this router with OpenWRT, what speeds have you noticed, wireless and wired? Would it be able to take advantage of a Gigabit connection? I read this thread from 2 years ago that said it was basically impossible for all-in-one routers under OpenWRT to do so, but this one is recent so I'm wondering. Thanks!

Edit: just saw this post, sorry!

Hey @ptthstr

Symmetric 1Gbit/s NAT is no problem :slight_smile:
With iPerf3 I can saturate the 2,5G port with at least 2,3G

Good to know, thank you!

Another question for those who have tried it: can the AX4200 handle SQM at Gigabit speeds? Thanks!

with 1.4 ghz processor you can sqm to 400/400

if you want calculate aproximative with ax4200 asus

for the nat witouth sqm he work with fiber easy

Iā€™m pretty much sure its Quad core ARM53 CPU, with 2GHz and irqbalance installed, will have no problems handling 1/1Gbps SQM cake.

Iā€™m expecting the router to arrive this week, so will confirm once OpenWRT is installed.

Is there anyone who already has it that can say for sure?


yes so this test ?? do you has a good sqm with this

A post was split to a new topic: Selecting a USB-TTL adapter and installing OpenWrt onto Asus TIF AX4200

I see that 23.05 came out, is this device included? I know it's in snapshot currently.
