Getting Started

Instructions have been moved to https://github.com/francoism90/asus-router. :)

@Limpi1978 Download this modified init-start script: https://mega.nz/file/is4FSDgD#9m4A7N-r6BomeU1n7SfrF9ZE9_036454nwAjmzA9_nM Copy this init-start script to your router into the folder jffs/scripts. (I use WinSCP to copy files onto my router) Make the init-start script executable (x in file properties). Make sure you "Enable JFFS custom scripts and configs" in System settings on your router. You don't need to format JFFS. SSH into your router and enter these commands:

nvram set jffs2_exec=/jffs/scripts/init-start nvram set jffs2_scripts=1 nvram commit reboot

You can modify the init-start script to your likings. See if it works.

Btw. I use channel 48 for 5GHz after extensive testing. With 48, I get the best results in range and speed. (80MHz channel bandwidth)

You seem very knowledgeable on this. Can you please explain how I can enable all the channels on it? Mine has many locked out.

Hi all, I think my question is off topic, but does anyone know which variable in nvram to enable 4x4 (4T4R) streams on the 5ghz band? Or maybe use the wl command?
I have an asus tuf-ax3000 (v1), the 5ghz chipset is capable of 4x4 streams, but it is locked to 2x2 by asus.

@alfky12 Interesting! :)

You could run nvram dump, and check if it's being exposed.

Thanks for responding. What does "check if it's being exposed" mean? I've dumped it and it's not encrypted.

is there a nvram show / get / set guide for Mediatech based TUF-AX6000?

@ALL I have moved the instructions to a repo instead, this makes it easier to maintain (branches, wiki, etc.).

Thanks again to all your contributes. :)

Hi all. Firstly, many thanks for doing this. It is greatly appreciated! Managed to get this going on an ASUS RC-AX58U V2 running a Merlin fork: RT-AX58U_V2_3004_388.8_2 and an ASUS RC-AX88U running Merlin firmware RT-AX88U_3004_388.8_2.
Downloaded the:
init-start
File available at:
https://mega.nz/file/is4FSDgD#9m4A7N-r6BomeU1n7SfrF9ZE9_036454nwAjmzA9_nM
Copied the file into my:
jffs/scripts
Folder using WinSCP. One thing not mentioned regarding this is that when setting up WinSCP, you need to choose the session file protocol:
SCP
I didn’t know that although do now and as these routers are Linux based, this will also work when accessing a Raspberry Pi.
Other things worth mentioning. Although I got this working, I can’t select any Wireless channels above 140 on 5G on my RC-AX88U. No idea why and the only way that I can select above channels 128 is to set this to 20/40/80 MHz Not running 160Mhz on WIFI6 as 80MHz is fast enough. Wonder if anyone can access channels above 140 on an RT-AX-88U? BTW, can access all 5G channels including 149 on my RC-AX58U V2 with this script running.

Hi all.
Thank you for all informations you posted here.
These are my settings for my router RT-AX5400, firmware 3004.388.8_2-gnuton1.
