我在用
Description: Ubuntu 20.04.6 LTS
Release: 20.04
Codename: focal
当我执行 ifconfig -a usb modem 时显示以下输出
wwan0: flags=4240<POINTOPOINT,NOARP,MULTICAST> mtu 1500
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

我该如何解决这个问题，我多次使用调制解调器驱动程序
