Power off wifi consumption

  • Hi all,

    I have an omega2 with ethernet expansion board and I would like to reduce consumption to minimum using just ethernet connection and disabling Wifi module.

    I tried to power off module by "ifconfig ra0 down" but the power consumption is practically the same, about 150mA.

    do There are any way to eliminate/reduce the WiFi module consumption. This will actually reduce the total power consumption of the Omega2?


  • @pablo-campos You should completely switch off the WiFi radio in the '/etc/config/wireless' file with option disabled '1'

    • up to FW version v0.1.10 b160
    config wifi-device 'ra0'
    	option type 'ralink'
    	option mode '9'
    	option channel 'auto'
    	option txpower '100'
    	option ht '20'
    	option country 'US'
    	option disabled '1'
    • from FW version v0.2.0 b175
    config wifi-device 'radio0'
    	option type 'ralink'
    	option variant 'mt7628'
    	option country 'US'
    	option hwmode '11g'
    	option htmode 'HT40'
    	option channel 'auto'
    	option disabled '1'
    	option device_mode 'apsta'
    	option op_mode 'preference'

    Good luck.

  • Thanks György

    consumption drops now to 110mA
