Changing Wifi Guest password from the shell?

[kobari]

Hi,

I would like to change my guest wifi password automatically with crontab, e.g. every week.

Is there any way of changing any wifi network password from the shell? Any help is appreciated here.

Thanks.

The values are stored in the nvram. To find out which values need changing type in SSH;

nvram show | grep GUESTPWHERE

Not sure the exact value as I don't have a guest network configured, but I assume it will be similar to the regular network values.

e.g

wl_wpa_psk=INSERTPW
wl0_wpa_psk=INSERTPW
wl1_wpa_psk=INSERTPW

nvram settings for the three guest 2.4 networks:
wl0.1_wpa_psk
wl0.2_wpa_psk
wl0.3_wpa_psk

nvram settings for the three guest 5.0 networks:
wl1.1_wpa_psk
wl1.2_wpa_psk
wl1.3_wpa_psk

to change the password for one of the six with cmd line:
nvram set wl0.1_wpa_psk=newpassword
