RUT240 : set WiFi power to maximum

Hello,
On a RUT240, I’d like to increase the Wi-Fi power to the maximum possible. The “iwinfo wlan0 txpower” command gives 16 dBm, while the maximum displayed is 18 dBm:
root@RUT240:~# iwinfo wlan0 txpower
0 dBm (1 mW)
1 dBm (1 mW)
2 dBm (1 mW)
3 dBm (1 mW)
4 dBm (2 mW)
5 dBm (3 mW)
6 dBm (3 mW)
7 dBm (5 mW)
8 dBm (6 mW)
9 dBm (7 mW)
10 dBm (10 mW)
11 dBm (12 mW)
12 dBm (15 mW)
13 dBm (19 mW)
14 dBm (25 mW)
15 dBm (31 mW)

  • 16 dBm (39 mW)
    17 dBm (50 mW)
    18 dBm (63 mW)

Yet, in the /etc/config/wireless file, there is “option txpower ‘18’”
Can you help me?
Thank you very much!

Hello,

The transmit power for the WiFi band can be adjusted by navigating to Network → Wireless → General Setup settings in the device’s WebUI. There you can set the desired transmit power up to 100%.

You can find more detailed information on this process on wiki page here: RUT240 Wireless - Teltonika Networks Wiki

If you have any further questions, feel free to reach out.

Best regards,

Thanks for your reply, but the setting in the interface is already 100%, and “iwinfo wlan0 txpower” shows 16 dBm, instead of the maximum of 18 dBm.
I tried running “iw dev wlan0 set txpower fixed 1800”. The setting remains for a few minutes, then returns to 16 dBm.
Is it possible to force 18 dBm?
