Power off wifi consumption

pablo campos

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?

Thanks

@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
