Hi,

I got problem with iwlist command, I tried to query txpower info, but I got no asnwer, only the prompt.

root@DD-WRT:~# iwlist ath0 txpower
root@DD-WRT:~#

Running iwconfig does not show up ath0 interface:

root@DD-WRT:~# iwconfig
vlan1 no wireless extensions.
lo no wireless extensions.
br0 no wireless extensions.
tun2 no wireless extensions.
eth0 no wireless extensions.
vlan2 no wireless extensions.


However,ifconfig shows ath0 interface:

ath0 Link encap:Ethernet HWaddr B0:48:7A:B0:17:62
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:663381 errors:0 dropped:0 overruns:0 frame:0
TX packets:672564 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:612973861 (584.5 MiB) TX bytes:656995130 (626.5 MiB)



What can be the problem?

I tried these commands (TL-WR1043ND):

Code:
00 8 * * * root ifconfig ath0 up; iwconfig ath0 txpower 20; startservice lan
00 22 * * * root ifconfig ath0 down; iwconfig ath0 txpower 0


And there seems to be some kind of problem. When I execute the commands directly via the interface everything works as expected, but when I try to run them as a cronjob the 'down' section does not work (if I manually power the wlan off the 'up' part works as intended). The router is doing something (high cpu load, lag for a few seconds) but after that the wlan is still up... Any ideas?

This is my configuration
Code:
30 08 * * * root ifconfig ath0 up; iwconfig ath0 txpower 15; startservice lan
30 00 * * * root ifconfig ath0 down; iwconfig ath0 txpower 0
and works.

I've 21676. I read somewhere that some versions of dd-wrt have a bug on cron. Check

I have 22118 (BrainSlayer build). Where can I see if it has the cron bug? And why is the 'up' part working, but not the 'down' part?

If in part, cron works I don't think you are affected by this bug. Try to copy and paste my configuration and try again.. It's strange that not work.

For r21061 the above solution works great, for r25934 I had to put in an aditionally stopservice lan. Don't forget to startservice lan again (otherwise you won't be able to access the router using ip until next reboot).

15 1 * * * ifconfig ath0 down; iwconfig ath0 txpower 0;
45 6 * * * stopservice lan; ifconfig ath0 up; iwconfig ath0 txpower 12; startservice lan;
