Hi.
I want to dynamically change the wifi antenna power to save battery. I try to set txpower to a lower value.
I try to set it in /etc/config/wireless
config wifi-iface 'ap'
option device 'radio0'
option mode 'ap'
option network 'wlan'
option ifname 'ra0'
option encryption 'psk2'
option key 'xxxxxxxx'
option disabled '0'
option txpower '20'
option ssid 'Omega-xxxx'
But when i try to get the power info
# winfo ra0 info
ra0 ESSID: "Omega-xxxx"
Access Point: aa:bb:cc:dd:ee:ff
Mode: Client Channel: 1 (unknown)
Tx-Power: unknown Link Quality: unknown/100
Signal: unknown Noise: unknown
Bit Rate: 150.0 MBit/s
Encryption: unknown
Type: wext HW Mode(s): unknown
Hardware: unknown [Generic WEXT]
TX power offset: unknown
Frequency offset: unknown
Supports VAPs: no PHY name: ra0
There are not information in Tx-power field.
From my laptop the wifi omega strength signal has no change.
I have an Omega2 LTE.
How dynamically change the antenna power?
