Hi All!
I have Alcatel X602D 4G Usb modem, for using in OpenWRT
cat openwrt_release
OS: OpenWrt 18.06.4 r7808-ef686b7292'
HW: ramips/mt7620,
I cleared device with option "Reset to defaults"
and installed that packets:
opkg install kmod-usb-core kmod-usb2 kmod-usb-serial kmod-usb-serial-wwan kmod-usb-serial-option usb-modeswitch luci-proto-3g
and created file /etc/hotplug.d/usb/30-alcatel_x232d
with content:
#!/bin/sh
ALCATELX232D_PRODID="1bbb/22c/0"
if [ "${PRODUCT}" = "${ALCATELX232D_PRODID}" ]; then
if [ "${ACTION}" = "add" ]; then
echo '1bbb 022c' > /sys/bus/usb-serial/drivers/option1/new_id
logger -t HOTPLUG "${ALCATELX232D_PRODID} plugged in."
fi
if [ "${ACTION}" = "remove" ]; then
logger -t HOTPLUG "${ALCATELX232D_PRODID} was removed."
fi
fi
created new connection:
/etc/config/network:
config interface 'WAN3G'
option proto '3g'
option service 'umts_only'
option apn 'home.beeline.ru'
option username 'beeline'
option password 'beeline'
option ipv6 'auto'
option dialnumber '*99#'
option peerdns '1'
option device '/dev/ttyUSB1'
new ttyUSB present in devices:
# ls /dev/ttyUSB*
/dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3
added connection to WAN zone in
/etc/config/firewall
config zone
option name 'wan'
option input 'REJECT'
option output 'ACCEPT'
option forward 'REJECT'
option masq '1'
option mtu_fix '1'
option network 'wan wan6 WAN3G'
and 2 or 3 times device is connected over mobile ISP randomly
now log fills by this messages while device is connected:

, who knows please help.
