Here is my /etc/resolv.conf file,

Any help out there???

had the same problem with my RPI - found a solution here.

when executing these two line before calling quectel.CM the connection succeeds:

sudo ifconfig wwan0 down
sudo echo ‘Y’ | sudo tee /sys/class/net/wwan0/qmi/raw_ip

4

I added these two lines to the top of /usr/share/udhcpc/default.script

sudo ifconfig wwan0 down
sudo echo ‘Y’ | sudo tee /sys/class/net/wwan0/qmi/raw_ip

Awesome. I got an error:
pi@raspAP:~/files/quectel-CM $ sudo echo ‘Y’ | sudo tee /sys/class/net/wwan0/qmi/raw_ip
‘Y’
tee: /sys/class/net/wwan0/qmi/raw_ip: Invalid argument

Manually editing the file works though. :slight_smile:

awesome, these two lines solved my problem
