if the network timeout, it could be that you skip the state of sudo ip link set wwan0 down to sudo ip link set wwan0 up. Try again. But sometimes it is not this.
- then configure the IP address and the default route with udhcpc
sudo udhcpc -q -f -i wwan0

udhcpc: sending discover
udhcpc: sending select for 10.38.223.119

in case you connect quectel with srsRAN_4G that you have already masq the interface to `wlp9s0' the selected interface will be changed
sudo udhcpc -q -f -i wlp9s0
- check the assigned IP address
