i have 4g modem, which shoudld work via rndis
.
after inserting it in usb, i get these network interfaces:
- enp0s29f2u1
- eth0
but, i can't configure it.
after doing eject -t cdrom
i get another one interface: enp0s29f2u2.
and that one i can configure.
so now i have:
[root@nethvo ~]# ifconfig enp0s29f2u2
