Your modem may require additional kernel modules and/or the usb-modeswitch package. ## Usage Once installed, you can configure the 2G/3G/4G modem connections directly in /etc/config/network as in the following example: config interface 'broadband' option device '/sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.2/1-1.2.1' option proto 'modemmanager' option apn 'ac.vodafone.es' option allowedauth 'pap chap' option username 'vodafone' option password 'vodafone' option pincode '7423' option iptype 'ipv4' option plmn '214001' option lowpower '1' option signalrate '30' option allow_roaming '1' Only 'device' and 'proto' are mandatory options, the remaining ones are all optional. The 'allowedauth' option allows limiting the list of authentication protocols. It is given as a space-separated list of values, including any of the following: 'pap', 'chap', 'mschap', 'mschapv2' or 'eap'. It will default to allowing all protocols.
