change tx-power

[smeegul]

Hi everyone! bought a router Asus RT-AC1200 V2, I can't find a tx-power change. Can I tell you how to change tx-power?

 

[ColinTaylor]

Check the bottom of the Wireless - Professional page. If it's not there then you can't change it on that model.

Is it possible to change tx-power via the ssh command line?

It might be possible to reduce that power if that's what you want. But you won't be able to increase the power.

Yes, I need to reduce tx-power. How can this be done?

Try entering this command via SSH and seeing if it shows you anything:

nvram show | grep wl._txpower

Your router has completely different hardware and firmware than mine so that command might not work.

nvram show | grep wl._txpower
size: 25562 bytes (35878 left)
wl0_txpower=100
wl1_txpower=100

Try setting the power (for 2.4GHz and 5GHz respectively) to 50% as follows:

nvram set wl0_txpower=50
nvram set wl1_txpower=50
nvram commit

Then reboot the router to try and apply that change.

After rebooting see whether the values are still set by running the same command as before:

nvram show | grep wl._txpower

Thanks, it worked out.

nvram show | grep wl._txpower
size: 25491 bytes (35949 left)
wl0_txpower=50
wl1_txpower=50

Use a WiFi app that shows the signal strength at various settings (10,25,50,75,100) to confirm that it's actually having an effect. Some routers just ignore the number.

 

[smeegul]

I checked, yes the values change but the signal level does not change

The command "wl txpwr_target_max" actually shows current TX power
