Is it? It does not look like IPv6 format! I will double check it - thanks!
kill the following processes using: kill -9 $pid
/bin/sh /usr/bin/modem_signal …
eco /usr/bin/modem_manager.lua …
/bin/sh /usr/sbin/mwan3track modem_0001 …
/usr/sbin/crond -f -c /etc/crontabs …
Next, SUSPEND the following processes using: kill -STOP $pid
udhcpc -p /var/run/udhcpc-rmnet_mhi0.pid -s /lib/netifd/dhcp.scrip …
/usr/sbin/crond -f -c /tmp/gl_crontabs -l 10
/bin/ash -c sleep 30;. /lib/functions/modem.sh;check_ip
sleep 5
To verify that you suspended the related processes:
# ps | grep -v '\[' | grep ' T'
10873 root 1240 S grep T
12112 root 1232 T udhcpc -p /var/run/udhcpc-rmnet_mhi0.pid -s /lib/netifd/dhcp.script -f -t 0
16355 root 1236 T /usr/sbin/crond -f -c /tmp/gl_crontabs -l 5
18214 root 1232 T /bin/ash -c sleep 30;. /lib/functions/modem.sh;check_ip
21402 root 856 T sleep 5
After that see if the connection goes down again. It’s a process of trial and error. In my modem, the above steps gave me a stable connection.
