Hello.
I need to do that https://tushev.org/articles/linux-bsd/26/modified-script-to-reduce-wi-fi-transmitter-power-on-schedule-at-night-mikrotik-routeros. I tried this guide but I cant do anything.
May I receive some help how to do that? I need my 2011 router to work at 21dB during the day and 10dB at night.
Simply set a minimum value /10dbm/ for the transmitting power of the wireless interface in the tx power section - all rates fixed and the script will work! Change the desired values in the script too !
Hi! Thank you!
Ive already done this as you described (changing the values). I did copy-paste in terminal (changing hours and transmitted power) but nothing changes at all. Tx power in wireless section has not changed at all. It remains 15 (as I made it days ago). Did I make a mistake ?
Did you do this?
Аdd the script in the system section - scripts with changed values as desired . Then add a schedule in system - schedule to run the script at a certain interval - an example of 15 minutes. That is all !
Oh man thank you! I did it wrong first time.
Then I tried as you said but I cannot succeed.
I made this to show how I did it. but it doesn’t change anything .. i think
You forgot RUN in schedule :
/system script run number=1
But this is not the main setup error. You must change the tx power for All rates fixed as the minimum value in the script to work … 8dBm not 10 dBm in your case 
Wow I’m so stupid 
Thanks a lot for your support!!
That was useful!
