我在openwrt_imagebuilder-ath79-nand_3.4-main加载modemmanager uci-default的设置是
uci set network.modem=interface
uci set network.modem.device="$(uci get shadow.core.device)"
uci set network.modem.proto='modemmanager'
uci set network.modem.apn='internet'
uci set network.modem.metric='20'
uci add_list firewall.@zone[1].network='modem'
uci set 'network.modem.ipv6=0'
uci commit
