Hi Guys, good night.

Firmware: DD-WRT v3.0-r44715 std (11/03/20)
TL-WR1043ND V.1

I'm writing a simple custom script on DD-WRT console and the last step is reloading /tmp/ath0_hostap.conf.

All radio setting works as intended but I get one missing thing that is really bothering me. After loading the /tmp/ath0_hostap.conf as:

hostapd -B -P /var/run/ath0_hostapd.pid /tmp/ath0_hostap.conf ;

The feature "Channel Width" on dd-wrt console:
Wireless -> Basic config
the "Channel Width" value isn't properly displayed.
Before loading the config file /tmp/ath0_hostap.conf the "Channel Width" option display 40Mhz (as my initial setup and desire.)

but after loading config file /tmp/ath0_hostap.conf the "Channel Width" options display Full (20 MHz) and the "Wireless Channel" option is blank.

Does anyone know what is the ath0_hostap.conf variable that is responsible for setting the "Channel Width" option on the dd-wrt console?

Any help is really appreciated

It looks like that after loading the Atheros drive via insmod, it ups it as wlan0 instead of the expected ath0 and even after renaming it to ath0 with ip link, the dd-wrt console isn't able to find "Channel Width"....

hummm where I'm broking the console display x insmod ?

First, (and foremost) you should consider upgrading to the current release as of this post:

https://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2023/06-02-2023-r52869/tplink_tl-wr1043nd/

The router database is not up-to-date with current release information and may suggest builds that are broken for some devices.

Second, interface names were renamed "a while ago" to standardize them across all non-Broadcom platforms (not going to find the development commits for you to explain, sorry).

You need to adjust your script to modern nomenclature. Also, the channel width and other variables may be contained in nvram variables (nvram show | grep wlan0).

Enjoy.

Hi @dale_gribble39, thank you for the fast reply.

I don't know that I'm not running the last version of dd-wrt firmware but that was the firmware that I was able to upgrade after a broken upgrade console feature in dd-wrt =/

So, regarding the interface name, you are right, the default interface name is ath0 and after insmod the ath and ath9k modules it must be renamed from wlan0 to ath0 to main the dd-wrt standards and I think that is the issue because renaming it will probably change /proc/dev hardware address?

I think the Web Console is unable to load the Wireless -> Basic config
the "Channel Width" because of these "rename from wlan0 to ath0"

So in brief, do you know a way that even re-loading the Atheros modules (ath and ath9k) the interface would still initiate as ath0 instead wlan0?

Thank you

By the way, just upgraded it

Firmware: DD-WRT v3.0-r52869 std (06/02/23)

So let me perform some tests regarding insmod ath and ath9k.

Oh!! Now I got you! In this new version, we are using wlan0 as default! Cool!

Actually, I will let it running on this new version to see if the radio will stop as it was stopping before.


I hope that this new version fixes the issue =) It would be perfect.

By the way.

That is what I was planning to do:

# Fixing connection issues

# Dump
#hostapd -P /var/run/ath0_hostapd.pid -dd /tmp/ath0_hostap.conf ;

rmmod ath9k ;
rmmod ath ;
ifconfig ath0 down ;
killall hostapd ;
insmod ath ;
insmod ath9k ;
ip link set wlan0 name ath0 ;
ifconfig ath0 up ;

# Load
hostapd -B -P /var/run/ath0_hostapd.pid /tmp/ath0_hostap.conf ;

#-------------


Now even if the new version keeps stopping the radio I can remove the line:
ip link set wlan0 name ath0 ;

I believe that this was what "bugs" the Web Console.

Thank you so much @dale_gribble39!

I would think the easier options would be:

Yep, it freezes this morning after like running for 10h so I created a custom script with your suggestion and enabled cron. Let's see how it behaves =)
