I am using build r42803.
In Administration cron I put

15 11 * * 6 root iw dev ath0 startservice radio_off
30 12 * * 6 root iw dev ath0 startservice radio_on

and after apply settings, rebooted the router (unplugged).

I was attempting to turn off ath0 at 11:15 am
and turn it back on at 12:30 .
All I have tried does not work. I think it was kong that suggested something similar to this. Might I get some easy to follow help on this?
I just want to kill that radio for the time I specified on Saturday.
Thanks much

You can do this hourly, via the webGUI, Wireless - Basic Settings - Radio Scheduling section.

I am not sure what command it is running to do it though.

[Eber]

I have not seen in Radio Scheduling where I could just shut off the Radio at 11:15 to 12:30.
Or that it would be just on Saturday.
And I did already look into Radio Scheduling.
Thank you for your input, but I need help with the
Administration Cron entry.
Thanks

It took some digging but I found the solution: https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1083400#1083400

That script should work.

I can see you said you already tried it. Do you know how where to paste the scripts in the webGUI?

[Eber]

I believe-
Service commands but not sure if it should be Startup or what.
Are you saying I need to use that entire script for ath0 on or off?
I downloaded plazmas txt attachment.
I did not try that specific one as I was not sure of it.Yet.
The second user variable set confused me totally.
thanks

[ian5142]

In your case the user variables should be, ath0 is 2.4GHz only, add ath1 for 5GHz:

IFNAME=ath0

START="0030"
STOP="2315"

Make sure they are in 24 hour time.

The NTP server at the top can be changed to whatever pool.ntp server you use. I use one of the Canadian ones, 0.ca.pool.ntp.org

From my understanding it all must be saved as a Startup script. Note this comment in the script as well:
# DONT FORGET TO ADD THE CRONTAB JOB IN THE GUI (SANS QUOTES)
# "* * * * * root /bin/sh /tmp/wifi_cron_switch_run.sh"

FWIW, I seem to recall that putting in your own NTP yielded issues with the router and it not using them...best to just use the dropdown and choose your region/territory and let dd-wrt use the built-in servers it uses. AFAIK, I never saw/read that the manual ntp address got corrected.

[ian5142]

Yes, but this NTP server is part of the script ran as dd-wrt is booting up. Separate from the NTP server on the bottom of the Setup page.

[Eber]

Thank you for your information so far.
I need a bit of help understanding the on off time.
1. I am guessing 0030 is 12:30 am?
2. It looks like the way this is written, if i did not put a start time in the router would never enable ath0 It would always be off.
So for Saturday morning 11:15 am to 12:30 pm
start 1115
stop 0130
Wouldnt that only turn the radio on for that short period of time?
If so, I would need 2 entries
start 0030 0130
stop 1115 2330

Allow me to give a brief explanation why i dont just go try this. It is my church router, i would have to go back and forth in my car to test these things each time i learned something new. We livestream at 11:15am and the church members wont get their butts off the net and we have limited upload.
The goal is to force them off for that period of time.
It would seem like there would be a simpler way to keep em off for that period of time. I even tried setting my tablet to static ip (cause i do need net access) and set the restriction range of ips to all given by the router (100-150)with all static beginning at 2.
I thought that should have worked but it did not kick off anybody already on.
I just need to wrap my head around that start and stop
and the admin cron entry- because it does not show stopservice startservice or something like ath0 off, ath0 on ect ect.
Thanks

Do you have a DD-WRT router at home to test it on? If not, I will try and test it today. I have way to many routers to test it on.

[Eber]

unbelievable since i never throw any out, but not one atheros at home to try it on.

[ian5142]

Set the START time to when you want to Turn wifi on.
Set the STOP time to when you want it to turn off.

Not, START must be before STOP time. Each START must have a corresponding STOP time.

So, you want to turn off wifi between, 11:15 am to 12:30 pm.

Then use:

START="0000 1230"
STOP="1115 2359"

If you have a dual band router, use:
IFNAME ath0 ath1

I left the NTP server as it was and it worked fine.

[Eber]

I tried it and I put in the admin crontab

15 11 * * 6 root /bin/sh /tmp/wifi_cron_switch_run.sh

I tried with quotes and without , but it did not work.
the crontab job is written wrong?
11:15 saturday to run?
I also only used ath0 as I wished ath1 to stay on.
Did that mess it up?

thanks

Are you setting using the GUI in "Administration->Management->Additional Cron Jobs" and have the radio button "Cron" set to "Enable"? Make sure your build is r41189 or bigger since cron was unreliable before that.

[ian5142]

You put the time you want in the initial script, on and off time (the part that is saved a startup script). Then you set the cron script to all stars, so it runs every minute.

You only have the script start running at 11:15am, by the time it gets to turning off the wifi section, it is probably not 11:15am anymore.
