Hello! I am able to use screen to communicate and run AT commands. I even have an ip address as verified by at+cgpaddr. When using qmicli to communicate any and all commands involving the modem fail (shown below). My goal is to be able to use the wwan0 interface to ping (currently not working). I’…

ok, MBPL was unnecessary here as those drivers are included in the openWRT kernel under the opkg names kmod-usb-serial-qualcomm, kmod-usb-net-qmi-wwan, qmi-utils. I went over your guide again and I can ping through the wwan0 interface. Thanks for your help.

Thanks Jyijyi, I decided to use openWRT, so this became a little easier. I installed kmod-usb-serial-qualcomm and things seem to be okay on the linux side of things.On the modem however, even though the modem is attached to the network (at+cgpaddr gives an ip address for pdp context: 1), I get the …

So you don’t install the MBPL driver? Did you try with Ubuntu PC first?

Yes, On Ubuntu everything worked well. I was able to ping google.com after following your very useful guide. On openWRT I did not install MBPL drivers, but it looks like the qmi utility (uqmi) can talk to the modem.
