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.
Confirming it works on RT-AX58U, Merlin 388.1 😁
(probably works on RT-AX3000 as well)
@barkmarkin since you wrote it won't work on your AX58U
I have two RT-AX58U and was able to increase transmit power and to select all possible 5 GHz channels. I was on country
wl1_country_code=E0, wl1_country_rev=742
before.These steps worked for me, but only exactly like this!
(also non-IT-guys should be able to follow this)
Alternatively change those things via
nvram set
.nvram dump | grep jffs
you should then havejffs2_auto_erase=0 jffs2_enable=1 jffs2_format=0 jffs2_on=1 jffs2_scripts=1 jffs2_state=3 log_path=/jffs
You don't need to setjffs2_exec=
init-start
, store it in/jffs/scripts
chmod +x init-start
./init-start
DO NOT try to change channels via Web-GUI or via console after reboot! This will not work and reset back to the old country settings!!
Example of one of my
init-start
file, where I only wanted to change 5 Ghz channels:Note: You select the most upper channel with
nvram set wl1_chanspec=161/80
, the control channel is then the lowest of those four 20 MHz channels, i.e. 149, see wikipediaMy lenovo laptop connects as (omitting some details here)
UPDATE: Asus 58U also supports UNII-4 Band!
