How to see current wireless tx power?

[erhtun]

Hi,

Is there a ssh command to see current wireless tx power of RT-AX68U? In web interface, it doesn't show tx power in mW unit.

Yes, there are:

This is for 2.4GHz

wl -i $(nvram get wl0_ifname) txpwr_target_max

And this is for 5GHz

wl -i $(nvram get wl1_ifname) txpwr_target_max

You need to enter it in SSH, I assume you already know how to use SSH.


For other models, the commands are almost universal, but for the GT-AXE16000 there are some differences there (read more)

Thank you for your reply.

I get theese results

wl -i $(nvram get wl0_ifname) txpwr_target_max
Maximum Tx Power Target (chanspec:0x1001):    13.50  13.50  13.50

wl -i $(nvram get wl1_ifname) txpwr_target_max
Maximum Tx Power Target (chanspec:0xe32a):    16.25  16.25  16.25

Are theese result in mW unit?

current it is not max:
2.4

wl -i $(nvram get wl0_ifname) txpwr_adj_est

5

wl -i $(nvram get wl1_ifname) txpwr_adj_est

Spoiler: Example:

maximum:

wl -i $(nvram get wl0_ifname) txpwr_target_max
Maximum Tx Power Target (chanspec:0x180b):      26.00  26.00  26.00  26.00
wl -i $(nvram get wl1_ifname) txpwr_target_max
Maximum Tx Power Target (chanspec:0xeb32):      26.00  26.00  26.00  26.00

current:

wl -i $(nvram get wl0_ifname) txpwr_adj_est
Last adjusted est. power (chanspec:0x180b):     25.50  25.75  26.25  25.25
wl -i $(nvram get wl1_ifname) txpwr_adj_est
Last adjusted est. power (chanspec:0xeb32):     26.50  26.25  26.50  26.00

Are theese result in mW unit?

My guess is they are in dBm - 13.5 dbm is 22 mW and 16.25 dbm is 42mW.

Do you have your GUI set to something less than the highest setting? Those seem a bit on the low side but if you've decreased the power then they make sense.

My AC68U reports 18.5 for 24. and 22 for 5

That's assuming the router is not incorporating the antenna gain into the dBm result it is reporting, I don't know if these routers do or not. If they do, then you'd need to deduct that from the result, then convert it to mW to get an accurate reading.
