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.
If you are using AiMesh, you might need to change the node as well.
Another thing you can try is to check to read the values for wl_chanspec, wl0_chanspec, wl1_chanspec and wl2_chanspec.
I don't remember, but some of the info floating around is wrong. They are referring to wl1, when it should be wl2.
Some stuff also just doesn't work as expected. Like the reg_mode. It appears as if you can it independently, but it just bounces back to whatever after reboot. BUT if you change the country code then the reg_mode is also changed automatically.
The whole thing is a mess with limited transparency because of boards/people are afraid of getting heat from the manufacturers.
I'd do a nvram dump as they suggest in the very first top post just to see what settings are already present and defined in the config.
