Power off wifi consumption
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'
consumption drops now to 110mA
