This may enable additional channels and power (in most cases don't) on ASUS Merlin provided routers.
The nvram settings have been tested on a ASUS RT-AX58U, they may work on other models as well (ASUS RT-AC78U).
Please use nvram dump
and adjust when needed, as they may differ on your device!

nvram dump > dump.txt
NOTE: You need to copy the dump.txt (or output by
nvram dump
to somewhere else), as they will be lost on reboot
Make sure
Enable JFFS custom scripts and configs
, is enabled in System settings. See https://github.com/RMerl/asuswrt-merlin.ng/wiki/User-scripts for details.
Make sure to also run the following commands:
nvram set jffs2_scripts="1"
nvram commit
Create the /jffs/scripts/wl
file, and paste the nvram
overwrites into this file (see given example file).
Create/adjust /jffs/scripts/init-start
:
#!/bin/sh
[ -x /jffs/scripts/wl ] && /jffs/scripts/wl &
# [ -x /jffs/addons/AdGuardHome.d/AdGuardHome.sh ] && /jffs/addons/AdGuardHome.d/AdGuardHome.sh init-start & # place before addons
Create/adjust /jffs/scripts/services-start
:
#!/bin/sh
/jffs/scripts/wl >/dev/null 2>&1 & # wl
# /jffs/scripts/scmerlin startup & # scMerlin
Create/adjust /jffs/scripts/service-event
:
#!/bin/sh
if echo "$2" | /bin/grep -q "wireless"; then { /jffs/scripts/wl service_event "$@" & }; fi # wl
Create/adjust /jffs/scripts/service-event-end
:
#!/bin/sh
if echo "$2" | /bin/grep -q "wireless"; then { /jffs/scripts/wl service_event "$@" & }; fi # wl
Make sure the scripts are executable:
chmod a+rx /jffs/scripts/*
You need to reboot the router to apply changes:
reboot
To make the changes persistent, make sure to add them to the jffs/scripts/wl
script.
This doesn't seem to work for my original AX88U (non pro). Which is originally set to "DE" (Germany) region.
Trying nvram command
I followed all the steps above and uncommented:
nvram set wl0_sel_channel=14/80 # force 2.4GHz channel
To try and set the 2.4Ghz channel to 14. After rebooting the router, it is still set to 13.
Trying Web GUI
I can see 14 as an option the "Wireless" tab in the router control panel.
If I try to set it to 14 in the Web GUI it reboots and sets it to 5 (Auto)...
If I go to Wireless > Professional > Right Click "Inspect" > CTRL+F "Country" > It shows "#a" like it should in the hidden setting.
Any other suggestions? I am just trying to get channel 14 because in the capital city every single other channel is completely saturated...
Here is my script. Do I need to replace the country code
#a
with something else? Is that why it's not working?Seems there's nothing I can do to actually use Channel 14 for 2.4Ghz.
