I want to be able to reduce the Tx power using cron in order to inconvenience my teenage son at bedtime.

Atheros router so no wl command.

So far my best try is:

Code:

iw phy0 set txpower fixed 20
command failed: Operation not supported (-122)

Any ideas please.

I had the same problem as you... as it seem that command is deprecated. Try with something like this: iwconfig ath0 txpower 20

The Tx power is changeable in the GUI. Wireless tab - Basic Settings, then check the advanced tickbox. Atheros uses Tx power in dBm, where 30 dBm is 1 watt.

See this link for more info: https://www.dd-wrt.com/wiki/index.php/Atheros/ath_wireless_settings#TX_Power

clearly u didnt read. if thats not good enough, then just scrap that, and use access restrictions.

OR. if that still doesnt work, consider scrapping the idea period. hes ur son, hes a teenager, not a young child... (u know where im going with this but i wont say it)

Brilliant! Thank you, numerci.

The crucial detail is

Quote:

Note that the value this commands takes is in millibel-milliwatts (mBm) instead of the commonly used decibel-milliwatts (dBm). <power in mBm> = 100 * <power in dBm>

if those ones are not working you can try:
00 22 * * * root ifconfig ath0 down; iwconfig ath0 txpower 0
00 06 * * *root ifconfig ath0 up; iwconfig ath0 txpower 25; stopservice lan; startservice lan

as ath0 is part of the LAN to get it up and running you need start /stop lan command
