We are using the RM520N-GL 5G modem, which by default uses the qmi_wwan driver. When connecting to the internet with a 4G SIM card on Ubuntu 20.04, why does running ifconfig show ppp0 instead of wwan.
I think it should show “WWAN”,right?
Actually ,the internet is connecting ,but the “ppp0” message is very strange.
Additionally, how can I send AT commands to the RM520N-GL modem in Ubuntu?
