Hi, I have a TP WR841N v8 with DD-WRT installed from this page (http://www.dd-wrt.com/phpBB2/viewtopic.php?t=161581&postdays=0&postorder=asc&start=195)

The reason I wanted to install DD-WRT was so that I could schedule the wifi to turn on and off at certain times. I have found lots of guides saying that I can schedule in the UI by going to 'Wireless/Advanced Settings' but I cannot find where to do it. Attached is a screenshot of the settings page, can someone tell me what I am missing.

Alternatively some forums suggest that cron jobs is the way to do it?

Thank you

Any help would be greatly appreciated. If I have bought a router which is not compatible with the feature of scheduling wifi on and off times could someone recomend me a cheap one on amazon that can do it?

thank you.

Just use cron (admin/management tab) as in the example below (on at 9am everyday, off at 10:30pm everyday)

Quote:

00 09 * * * root /sbin/ifconfig ath0 up
30 22 * * * root /sbin/ifconfig ath0 down; iwconfig ath0 txpower off

Thanks Sanist but unfortunately that is doing nothing. I copied the code exactly into the cron then saved, then applied settings, then rebooted the router. The only change I made to the code was the times to test it (always using the 'mm hh ' format, I then logged into the 'status window' to see if radio turned off which it did not, I also used my phone to search for wirless and it was there. Any ideas?

Thank you

Thanks Mile-Lile.

I had read that thread and I had put this in the cron but it still does not do anything:

20 08 * * * root wl radio off
25 08 * * * root wl radio on

Does anyone know why it is not working?

Thanks.

If no one can help with this can anyone point me to the cheapest router that will run the version of DD-WRT that I need to be able to set the schedule in the UI?

Thanks

Hello, I have the same router and the same problem you do. I noticed that using

/sbin/ifconfig ath0 down

wifi radio was correctly shut down.
However using

/sbin/ifconfig ath0 up

didn't work to bring radio on.
I noticed though that if I reset the router it starts with wifi radio ON.
So I modified my cron commands in this way, and it works for me:

0 02 * * * root /sbin/ifconfig ath0 down
0 07 * * * root /sbin/reboot

(change the times to suit your needs).
You will have a minute or so of connectivity down (when the router is rebooting) but it doesn't matter in my case.

Hope this helps, cheers.

Now I understand why my initial solution works: I too had a daily scheduled reboot shortly before the scheduled wifi on command.

I had set up the reboot just to clear up memory daily, to prevent any possible teething issues after I set up the router.

Seems like I can now remove the redundant wifi on command, and move the reboot to cron to keep a consistent picture of the schedule.

thx

I found this thread why looking for a solution to schedule the wifi on atheros units.

However it didnt work for ath0 didnt come backup, probably something has changed in modern builds.

Ive posted a working solution to the problem here for anyone that stumbles onto this thread.
