Hello,
I'm struggling to make cron jobs to set the antenna to turn wifi off everyday between 22:00 and 09:00. This is what I'm putting in Additional Cron Jobs:
Quote:
0 22 * * 0,1,2,3,4,5,6 root wl radio off
0 9 * * 0,1,2,3,4,5,6 root wl radio on

The device is a NanoStation M2 with firmware v24-sp2.
I must be doing something wrong but I don't know what.
Can anyone help me?

On my DD-WRT v24-sp2 (06/08/12) mini - build 19342, I can do it from the web interface:

Wireless -> Advanced Settings 'Radio Time Restrictions'

Works OK.

Ok thanks,
I'll have to upgrade my firmware then because I don't have that tab.

I'm surprised - you have V24-SP2 the same as me! I would have thought access restriction was supported. Does this page help?

So I'd have to reflash the Nanostation to build 19342?

I am currently on 17201.

Thanks

I'm sorry I can't help any further 'fmdeixt' - I'm at the limit of my knowledge with DD-WRT!

Sorry for being so stupid.

I see now the advanced settings tab, and there is no radio time restrictions option,
so as Sash hinted, it must be impossible.

I'll get a timer switch and be done with it.

Thank you.

Ok thank you,
I'll give it another try.
So the first thing I'm thinking after a bit of reading is settig tx power to 0.
This would be the notation in terminal

Quote:
iw dev <devname> set txpower <auto|fixed|limit> [<tx power in mBm>]


And to adapt it to my particular case in cron jobs I'd replace wl radio off so the result would be like this

Code:
0 22 * * 0,1,2,3,4,5,6 root iw dev wlan0 set txpower fixed 0
0 9 * * 0,1,2,3,4,5,6 root  iw dev wlan0 set txpower fixed 2000


Would this work?

Well, I'll go and try it, even though not with much hope.

Well,

In telnet iw dev wlan0 info returns no such device, only phy0 exists and does not accept the set txpower command.

I just don't know what creating a dev interface would do, so I found the limits of my knowledge again.

There's not much documentation for this so I'll have to give up again.

Nice try, thanks.
